I have parallels 10 and I am running windows XP. Do I need an antivirus, if I am not using any emails or seldom browsing?
If so which one is compatible with the virtual machine?
Thanks,

easy way ms free virus scanner thingy
free way avast virus scanner

What is the recommendation for cleaning ones sensor? I have a 5D.

What is the recommendation for cleaning the sensor on the 5D III
Thank you,
M

The manual recommends using a blower when the automatic cleaning fails - or better yet, sending it to Canon for service. Sometimes - rarely - a blower will work and is the simplest and reasonably safe thing to use.
Otherwise many like the Sensor Swab solution. It is tedious and expensive, but I have used it effectively several times - especially on the 5D that seemed more prone to spots than the newer models. The problem I always have is going from bad to worse to finally better - a lot of patience is required and wasting or going through several of the swabs is not uncommon. Maybe my technique sucks, but I find it takes a lot of time and swabs to be eventually be satisfied. That said, I have never caused any damage and I have always managed to finally get the sensor clean. Along with the swabs, good lighting and magnification (reading glasses or similar) is also necessary as the spots that look huge on a photo will be nearly invisible.

I just purchased MBP and it is my first Apple computer. How concerned should I be about virus software and what do you recommend for security software?

I just purchased MBP and it is my first Apple computer. How concerned should I be about virus software and what do you recommend for security software?

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.)
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been another layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't actually been tested by Apple (unless it comes from the Mac App Store), but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe.
Gatekeeper has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could find some other way to evade Apple's controls.
For more information about Gatekeeper, see this Apple Support article.
4. Beyond XProtect and Gatekeeper, there’s no benefit, in most cases, from any other automated protection against malware. The first and best line of defense is always your own intelligence. All known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source. How do you know whether a source is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
5. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was never a good idea, and Java's developers have had a lot of trouble implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style "virus" affecting OS X. Merely loading a page with malicious Java content could be harmful. Fortunately, Java on the Web is mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers. In Safari, this is done by unchecking the box marked Enable Java in the Security tab of the preferences dialog.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a specific task, enable Java only when needed for the task and disable it immediately when done. Close all other browser windows and tabs, and don't visit any other sites while Java is active. Never enable Java on a public web page that carries third-party advertising. Use it only on well-known, password-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow these guidelines, and you’ll be practically as safe from malware as you can be.
6. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
7. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
ClamXav is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
ClamXav may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use ClamXav unless a network administrator requires you to run an anti-virus application.
8. The greatest harm done by anti-virus software, in my opinion, is in its effect on human behavior. It does little or nothing to protect people from emerging threats, but they get a false sense of security from it, and then they may behave in ways that expose them to higher risk. Nothing can lessen the need for safe computing practices.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.

What OS is recommended for LabVIEW to run on a PDA?

I want to send information from a PDA via RS232 to a lens. I'm wondering if LabVIEW 6.1 will run on a PDA or if its an exe that is loaded onto the PDA. If a new version of LabVIEW for PDA's is available. Finally, what OS is recommended for LabVIEW to run on a the PDA, I've been looking at MS Windows for Pocket PC. Thanks.

Have you looked at the Linux version of the Sharp Zaurus SL-5500 PDA. I
believe there are several Intel processor based PDAs that can run Linux.
Since they can run Linux, they can run LabVIEW for Linux. Wow, that's
awfully simple... perhaps I should get one. A used one on Amazon is
$380. Tell us how it goes.

What antivirus is needed for iPad

What antivirus is there for the iPad.

none. not needed. nothing to worry about. That why we like the closed IOS system on the iPad.

What software is recommended for the maintenance of mac?

What software is recommended for the maintenance of mac?

How to maintain a Mac
1. Make redundant backups, keeping at least one off site at all times. One backup is not enough. Don’t back up your backups; all should be made directly from the original data. Don’t rely completely on any single backup method, such as Time Machine. If you get an indication that a backup has failed, don't ignore it.
2. Keep your software up to date. In the App Store or Software Update preference pane (depending on the OS version), you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis.
Keeping up to date is especially important for complex software that modifies the operating system, such as device drivers. Before installing any Apple update, you must check that all such modifications that you use are compatible. Incompatibility with third-party software is by far the most common cause of trouble with system updates.
3. Don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, such stuff is useless or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
The more heavily promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.
As a rule, the only software you should install is that which directly enables you to do the things you use a computer for, and doesn't change the way other software works.
Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception to the above rule. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction. Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve.
4. Beware of malware. Malware is malicious software that circulates on the Internet. This kind of attack on OS X used to be so rare that it was hardly a concern, but it's now increasingly common, and increasingly dangerous.
There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense. You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable.
Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must come directly from the developer's website. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from the web, without your having requested it, should go straight into the Trash. A web page that tells you that your computer has a “virus,” or that anything else is wrong with it, is a scam.
In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
5. Don't fill up your boot volume. A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a boot failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem.
While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage use and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
If storage space is running low, use a tool such as OmniDiskSweeper to explore the volume and find out what's taking up the most space. Move seldom-used large files to secondary storage.
6. Relax, don’t do it. Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
Let go of the Windows mentality that every computer needs regular downtime maintenance such as "defragging" and "registry cleaning." Those concepts do not apply to the Mac platform. The machine should not be a focus of your attention. You shouldn't have to think about it at all. It should be a transparent, almost unnoticeable tool by means of which you communicate, work, and play. If you want a computer that depends on you to keep going, use a PC.
The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.

What antivirus is better for those who work with mac and windows?

In my home I use an iMac, but in college I use Windows, and more than once I found an infected file. I know not affect iMac, but I prefer that viruses are removed. Right now I use ClamXv, but I don't know if it is effective.
Am I to continue using ClamXv? or, do I use another?
If there are others better AV for mac, what is most recommended?
**I have also used Sophos, but it makes the iMac go very slow.
Thanks for your attention.

1. This is a comment on what you should and should not do to protect yourself from malicious software ("malware") that circulates on the Internet. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to your computer, or who has been able to log in to it remotely. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandboxing security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and Internet criminals. If you're smarter than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know what is safe?
Any website that prompts you to install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one, is unsafe.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders," for example, are outside the safe harbor, though not all are malware.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe. For instance, if a web page warns you that Flash is out of date, do not follow an offered link to an update. Go to the Adobe website to download it, if you need it at all.
There is an increasing tendency for rogue websites such as "Softonic" and "CNET Download" to distribute free applications that have been packaged in a superfluous installer that also installs malware or something else that you don't want. Never visit those sites, and get all freeware directly from the developer's own site whenever possible.
Software attached to email that you didn't request is unsafe, even if it comes (or seems to come) from someone you trust.
Software advertised by means of spam is unsafe.
Unknown "free" software that a stranger on the Internet is eager for you to download is unsafe.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
"FREE WI-FI !!!" networks in public places are unsafe unless you can verify that the network is not a trap (which you probably can't.) Even then, do not download any software or transmit any private information while connected to such a network, regardless of where it seems to come from or go to.
I don't say that leaving the safe harbor just once will inevitably result in disaster, but making a habit of it will weaken your defenses against malware attack. Doing any of the things alluded to above should make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. New threats are emerging on a daily basis. Research has shown that most successful attacks are "zero-day" — that is, previously unknown. Recognition-based malware scanners do not defend against such attacks.
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware, and even for that use it's not completely effective. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular trojan it is, but do you really care? In practice, there's seldom a reason to use the software unless an institutional policy requires it. Windows malware is so widespread that you should assume it's in every unknown email attachment until proven otherwise.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither should you assume that you will always be safe from exploitation, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. "Hmmmm, this torrent is a crack of that new game I want. I think I'll download it. It could be a trojan, but the antivirus will warn me if it is." Then they wonder why their Mac is so slow all of a sudden. It's slow because it's running flat out mining bitcoins for a hacker who has already sold their credit card number and banking passwords to a criminal gang. Maybe a week later the antivirus does warn them, but what good does that do?
Nothing can lessen the need for safe computing practices.

What do you recommend for me: MacBook Pro, iMac or Mac Pro?

I haven't decided what Mac I should buy. It's pretty hard for me. I'm fascinated with the iMac, MacBook Pro and Mac Pro. But I'm not sure what Mac is good for me. For now, I use my laptop for web browsing, sometimes photoshop and writing stories on notepad. But I'll probably do more later on such as developing 2D games and making music on GarageBand. I might make my own website with podcasts and possibly take advantage of Mac OS X's DVD creation software. I will also dual boot (Windows & Mac OS X which I'll use the most) and play games on it.
Money isn't a real problem. I only have $1,000 at the moment. But I'm going to get a job soon. I won't buy a Mac until the job is stable.
I don't know what to buy and not sure which one is the best for me. I like all 3 of them! I really like portability because I can take it anywhere. But I already have a notebook (not a Mac). I need a Mac that will last me a couple of years. Again, I'm afraid that newer stuff will come out and my computer will be inferior. lol.
So I'm hoping someone can help me come up with a decision. You guys/gals know more about computers than me. I'm new to Macs too. I became interested in Macs last year when I saw the Power Mac G5. I thought the tower looked awesome and then I started playing around with it.

I've never had an iMac wear out. My last one lasted four years and the guy who bought it from me on eBay reports that his is doing fine. It got HEAVY use in a dusty environment.
And Apple has been refining the iMac for years now. I keep hearing you emphasize durability, so that is why I am pushing it for you. No laptop will last as long. They operate at higher temperatures and take a beating. My Mac Book Pro already lost its back-lighting and has something wrong with the DVD eject feature. All repairable for free with Applecare, which I recommend. But my iMac will outlast my desire to own it, this I know for certain. I have the 20 inch and wish I had gotten the 24. If you're interested in my new 20", I will sell it to you for 1/3 off what I paid for it, and it comes with a transferable 3 year Applecare warranty. This way I could purchase the 24". It hadn't come out when I got the 20".
But first, come to the conclusion that you don't need an Apple laptop. That's the threshold decision.
Best of luck to you.

What are hardware recommendations for Forte 4gl 3.0.M.2 under HP_UX?

We are running into performance issues that seem to be related to cpu speed using Forte 3.0.M.2 fully compiled under HP_UX 11 on three server models: HP9000/D370, /D390, and /L1000. We see large numbers of select calls (at the os level) 200-300 in a 15 second interval, that pin cpu usage. On the D370 (Pentium 166MHz) the spikes last for as long as 5-20 seconds and our users are complaining. We have not had complaints (yet) about the D390s (Pentium? approx 240MHz) or the L1000s (PIII? approx 440MHz).
What cpu speed was recommended for 3.0.M.x? We strongly suspect we are expecting too much of the D370 boxes but need supporting information to make our case.

Hi Patrick,
I do not think your problem is CPU-related. What do you mean by select calls? If your select stament is a SQL Select one then what maybe is happening is that your data access methods are no longer effective due to an increse in the volume of data they are now handling. What I would suggest you is to find out which are the methods having problems and then find out what the code does. If you figure out the problem is the volume of data you are handling then you will have to change your code to implement a better data interaction.
Anyways... keep me posted... I will be more than happy in helping you out.

4.6C to ERP6.0 Upgrade - what are the recommendations for Unicode and Java

Hi All,
Forgive such a basic question.
We are just beginning to look at our ERP6.0 upgrade and am unclear whether we should convert to unicode at the same time, and also what are the uses for the Java stack.
Unicode?
We are a single language Latin-1 site so don't need Unicode. However will it become mandatory eventually? Are we better, if we have the opportunity now, just to convert. Also I believe the Java stack is only Unicode. Does ASCII ABAP and Java Unicode complicate things?
Java?
Will we need it? We are proposing a technical upgrade from our 4.6c Javaless environment. Where does Java come in to play in ERP6.0? Doesn't it increase greatly the iSeries HW requirements? (I'm looking at a 2 way 550 at the moment)
Look forward to hearing your views.
Regards
Steve

Hi Stephen,
at the moment, in a latin-1 environment Unicode is for old customers not a requrirement. This might change in 5-10 years ...
Java: No problem at all with ASCII (in latin-1 environments)
=> there is no need for you, but you could go for it. We did several Unicode conversions already and these Latin-1 conversions are pretty easy and simple especially on iSeries, because of the special InPlace Unicode Conversion.
... but this can be done at any time ...

Antivirus software recommendations for IMac ( OSX10.7.5) and ipad2

I know it has been discussed and re-discussed, but please update me on the latest recommendations as I was not able to upgrade a year ago to Mavericks (even with Apple Support on 2 occasions) and I am reluctant to upgrade to Yosemite due to the WIFI issues. Update tells me that my software on my Mac is up to date, but that is not the OSX.

Mac users often ask whether they should install "anti-virus" (AV) software. The usual answer is "no." That answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There is a threat, and you need to educate yourself about it.
1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions.
It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to take control of it remotely. That threat is in a different category, and there's no easy way to defend against it. AV software is not intended to, and does not, defend against such attacks.
The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't been checked for security by Apple unless it comes from the App Store, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
☞ It can easily be disabled or overridden by the user.
☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has taken far too long to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. Those lapses don't involve App Store products, however.
For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, not machine behavior, and no technological fix alone is going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and Internet criminals. If you're better informed than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software. A genuine alert that Flash is outdated and blocked is shown on this support page. Follow the instructions on the support page in that case. Otherwise, assume that the alert is fake and someone is trying to scam you into installing malware. If you see such alerts on more than one website, ask for instructions.
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Rogue websites such as Softonic, Soft32, and CNET Download distribute free applications that have been packaged in a superfluous "installer."
☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
☞ High-priced commercial software such as Photoshop is "cracked" or "free."
☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
Conditional or unsolicited offers from strangers
☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
☞ You win a prize in a contest you never entered.
☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
☞ Anything online that you would expect to pay for is "free."
Unexpected events
☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a padlock icon in the address bar when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial AV or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial AV products?
☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
☞ Most importantly, a false sense of security is dangerous.
8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It can be as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

What security is needed for Parallels on IMac? I keep getting notices it has expired from Kaspersky but I renewed it on 1/15/11 for a year. What's up?

My understanding is IMac has its own security that does not need to be updated/renewed. However, I have Parallels software so I can use Microsoft products for my job. It came with Kaspersky Internet Security. I've gotten a message that it expired and I need to renew it. I purchased a year's worth of security from the Parallels site on 1/15/11 so thought I was covered.
Do I need to purchase security for an IMac for the microsoft environment - specifically Parallels? If so, does anyone have a recommendation?

What does everyone recommend for a multi-function machine

We have a small office but need high speed printing and more importantly high speed scanning. We currently have a xerox workcentre that have been decent but is in need of repair. Instead of spending the money on that it is time for a new machine. I would like to stay away from xerox as I called them to help fix current machine and the only advice they would give me over the phone was two power down the machine for 15 seconds. Obviously this did not work and then they wanted $275 for the the 1st 15 minutes for a tech to come out, ridiculous. Anyway, what do you guys recommend? I am looking to spend around $2,500.

Call your local office equiptment service and sales, they can recommend the best product for your circumstances as they have exposure to many different machines and problems.

What would you recommend for this setup?

I just recently found Arch, and I love it so much I want to use it more.
I have been working on converting my media center pc's to Linux, and want some advice before moving forward. Here is what I have:
Living room (Main Media Center, 6 TB of storage, PS3)
Bedroom 1 (Media Center, Wii)
Bedroom 2 (Media Center, Xbox 360)
Bedroom 3 (Media Center)
Kitchen (Media Center)
I don't think the gaming systems matter, but wanted you to have the full picture.
What I would like to do is have a setup where the Living Room Media Center could be a media server for the other rooms, and also handle media for the TV it is connected to. Most of the movies we have are of two different formats:
VIDEO_TS folders for standard dvd's
MKV for HD movies
Is this type of setup possible with Arch, or should I use a Distro like XBMC completely?

I've been using several DLNA-servers on Arch for two years now. I started out with coherence (lacks transcoding support), fuppes (lacked surround sound support), mediatomb (no srt subtitles AND surround sound together), and now I'm using pms(-svn) that does all I've ever needed.
1 small problem: since an update several weeks ago, libmediainfo is not working together anymore with pms: pms crashes on indexing with libmediainfo and sometimes on playing a movie file. On the PMS forums, there is one other user complaining about the same problem, but that's about it.
That's why I recently installed minidlna and I'm very impressed by this little program, but it doesn't play MKV or FLAC iirc. For now I've settled on PMS without libmediainfo, which means from time to time, a movie isn't played in 5.1 (whenever a movie file has two audio streams, the first one is played instead of choosing the 6 channel audio as default).
Anyway: I'd recommend a dlna-server on arch anytime. The protocol is getting more and more support - even TV's are sold with good dlna-support out of the box... If all goes well, my new house will be ready next summer and it will be dlna-powered all the way.
