Any opinions about OpenGL4Java?

Any opinions about OpenGL4Java? I want to make a 3D game in Java using OpenGL. OpenGL is for C++, but there is a package or something called OpenGL4Java (I think it is put out jau software, ore soemthing like that, I don't have time to look it up now. Anyway, does anybody have any opinions about it?
And for all those who say that a good game cannot be done in Java, take a look here:
http://www.cosm-game.com/
It looks good for Java. Too bad it is only an online game.
Virum

Do you have any evidence for that?
That sounds really accusative, but I'm genuinely
interested in seeing some comparisons between the two
environments.I assume you are talkin about Java3D and OpenGL?
If so yes, I can give some evidence. My uncle knows a pofessional that has been working with graphics programming since he was twelve. I think he is somewhere around 29, but I don't know. Anyweay he uses uses OpenGl quite a bit, and he waas the one who told me that OpenGL gave much more control (it has direct access to hardware) than Java#D. Java#D may have now reached OpenGL's speed, but I don't think it has yet. ANyway, I want the control OPenGL gives you.
Has anybody else had any expereiences with both?
As to the portability thing, I have no idea where I heard Java#D had portability probelems.

  • Does anyone have opinions about at

         Does anyone have experience with or opinions about the free McAfee security suite offerd by At&t U-Verse? I would also ask the same about OpenDNS, which seemed to work fine on my old Mac. Thanks

    The McAfee product is much worse than useless.
    This is a comment on OpenDNS and other public domain-name system (DNS) services, such as Google DNS. You should use such a service if it solves a problem for you, and not if it creates problems you don't already have. To summarize:
    1. Using public DNS will probably not make your network faster, and may make it slower.
    2. It will probably not stop your browser from being redirected when you try to connect to a valid web address.
    3. It will not make you safer from malware attacks.
    4. It could cause confidential information to be compromised.
    5. It has other privacy implications that you should be aware of.
    A DNS server resolves the human-readable "domain name" of an Internet host, such as www.apple.com, to the numerical address by which that host can be reached. The process is analogous to looking up a phone number by name. There is no chance that changing the DNS server you use will have any effect on a network problem not related to name resolution.
    There are two valid reasons why you might want to use a public DNS service:
    The DNS servers provided by your ISP are misconfigured (perhaps deliberately) or don't perform well.
    You have a use for the filtering controls provided by OpenDNS and others.
    Although some DNS services are touted as responding faster than others, there will be no noticeable difference if your ISP is delivering what you pay for. Most likely, the difference in response time among the DNS servers available to you is on the order of a hundredth of a second or less. But under some conditions, public DNS will significantly slow down network performance. Here is a case in point.
    A content-distribution network (CDN), such as the one used by Apple to deliver software updates and iTunes content, relies on the location of the DNS server to optimize performance. If your query goes to a distant server, you may get slow downloads of Apple content, among other things. From the report of a test carried out by a networking consultant:
    We listed 9 CDNs that would benefit from supporting/using edns-client-subnet, and only two actually support edns-client-subnet: CDN77 and ChinaCache. Others, including Akamai, Internap and CDNetworks, do not currently. This really is too bad, because from the performance data we collected, it is clear these CDNs deliver (much) worse performance currently in many countries to Google DNS and OpenDNS users.   
    Another reason often given for using public DNS is to avoid "redirection," that is, false results from a query for a valid domain name. Ethical ISP's do not intentionally redirect valid DNS queries, though it might happen unintentionally because of a misconfiguration; for example, because the address of a network host has recently changed, or because of a "poisoning" attack on the DNS server. Note that many ISP's may, and OpenDNS certainly will, redirect invalid queries to ad sites, in violation of published standards for DNS.
    Recently, a few low-quality commercial ISP's such as "CenturyLink" have taken to deliberately redirecting DNS queries for some domains, such as search engines. Do not tolerate this practice. If your ISP is doing it, then you should demand that the redirection be stopped, or else switch to another ISP.
    Some ISP's have been said to route all DNS queries to their own name servers, regardless of where the queries were directed—another intolerable practice. I haven't heard that any commercial ISP is now doing this, but if yours is, you won't be able to use a public DNS service, even if you change the network settings on your computer or router.
    Of course, if your Internet access is provided by an employer or institution, rather than by a commercial ISP, then you have to take whatever you get.
    The claims on the OpenDNS website that it blocks malware attacks such as "Flashback" are false advertising. A DNS service does not and cannot block anything. All it can do is to selectively refuse to answer queries. It's trivial for a malware attacker to evade such controls. It's just as easy to evade the parental controls offered by OpenDNS. Nevertheless, you may find those control features useful, despite their limitations. Here is an example of an ASC user who had undesirable results from OpenDNS content filtering.
    There is one limited exception to the rule that OpenDNS and Google DNS don't improve performance. The "prefetching" performed by modern web browsers, including Safari, may confuse some DNS servers, with the effects described in this Apple Support article. The article suggests testing OpenDNS, Google DNS, or another third-party DNS service as a possible way to overcome the problem.
    If you need to switch DNS providers because of a misconfiguration of your ISP's servers, the change will most likely only need to be temporary. The problem may be resolved automatically within a matter of hours.
    If you're considering whether to use public DNS, such as OpenDNS, on a long-term basis, you should take into account the privacy implications. As a user of the free service, you are not an OpenDNS customer, and the service provider—a for-profit corporation—doesn't have a contract with you. The marketers to whom OpenDNS sells access and information are its customers.
    OpenDNS will know, and store, the address of every Internet server you use from now on. This is from its privacy policy:
    When you use our Services, OpenDNS stores certain DNS, IP address and related information about you to improve the quality of our Service, to provide you with Services and for internal business and analysis purposes.
    Concerning personal information, the policy states:
    ...[I]t is disclosed to entities that perform marketing services on our behalf or to other entities with whom we have joint marketing agreements...
    You can't opt out of those disclosures. Read the privacy policy carefully and draw your own conclusions. The privacy policy of Google DNS seems to be somewhat more benign, but again, you should judge for yourself.
    That's not the worst of it, though. The practice of hijacking nonexistent domains followed by most public DNS services could result in leaking confidential information to a hacker:
    For example, consider the "same origin trust model" used for Web cookies. If you're holding a cookie for GOOGLE.COM and you can be fooled into following a link to KJHSDFKJHSKJHMJHER.GOOGLE.COM, and the resulting NXDOMAIN response is remapped into a positive answer to some advertising server, then you're going to send your cookie to that advertising server when you send your HTTP GET request there. Not such a bad thing for a GOOGLE.COM cookie, but a real problem for a BANKOFAMERICA.COM cookie.  
    NXDOMAIN remapping is not something that only happens when you randomly mistype a domain name.  It can be exploited deliberately by malicious links placed on any web page. In the case of OpenDNS, the result would be that a cookie intended for another server would be sent to the OpenDNS web server instead. A rogue OpenDNS employee, or anyone who managed to break into the web server, might then be able to impersonate you on another website. If this scenario seems far-fetched, it's the stuff that network exploits are made of.
    See also a brief, and somewhat outdated, critique of OpenDNS on a Harvard Law School blog, with a response from the company's founder.

  • Opinions about freebsd 7.x ?

    Hi All,
    I am currently a very happy 11 year Arch / RHEL / fedora user but always looking for a new challenge. So I am thinking about switching my desktop pc / home server from Arch64 to FreeBSD.
    I read a lot of stories here about people switching to arch from gentoo or the bsd's but are there those that run freebsd as well or switched from gnu/linux to *BSD?
    I am interested in any and all opinions about freebsd and what you believe are it's (dis)advantages over linux. Package wise it seems to be on par with Arch apart from compiz and flash.
    Is the "whole operating system" thingy just a gimmick or does it offer (performance) advantages over a linux kernel + packages?
    I recently tried pcbsd7 and apart from sucky fonts it was not any less userfriendly then linux, although it does not offer the awesome pacman package manager of course, the PBI system seemed to work fine. But I'd think I'd rather go with freebsd 7.1 + kde 4.1.x then pcbsd (although they do have a cute KDE theme there for what it is worth).
    apart from being more geeky does freebsd offer anything over pcbsd?

    Rock solid my arse.
    PC-BSD tries to bring FreeBSD to the masses through more automation and wider compatibility.  It's based on FreeBSD's prerelease branch, and they also use their own kernel among other changes.  Naturally it's not going to be as stable as raw FreeBSD.
    The main reason I don't use FreeBSD full time is nVidia's lack of amd64 drivers.  An nv rep said "There are no plans to support FreeBSD amd64 at this point in time, but customer requests will certainly help prioritize future projects." but there still isn't one 24 pages and 4 years later.  I hate open-ended statements like this that string you along.. Personally in situations like this I'd rather they have just said "no" even if the door weren't really 100% shut

  • Does any body have any opinions on how much better CS6 is than Cs4?

    Does any body have any opinions on how much better CS6 is than Cs4?  The reason I ask is I am trying to convince my business partner that CS6 is worth buying 

    My pattern has been that every other new version made it worth my while. I spent very little time working in CS4, since I went from CS3, to CS4 with an immediate upgrade to CS5. Then from CS5 to CS5.5 with an immediate upgrade to CS6. I have not gone to the cloud, so cannot comment on the features there. I would still evaluate your price for CS6 against the rental expense.
    I like Todd Kopriva's page laying out the CS6 new/changes features:
    Premiere Pro CS6: what’s new and changed
    That page contains other links (e.g. CS5 and CS5.5 changes).
    In addition to cc_merchant's points about 64 bit (which were HUGE and for CS6 included Encore going to 64 bit), I found these items from the "new" list as important to me:
    adjustment layers (HUGE)
    expanded multi-camera editing, with more multicam angles and improved interface (I hated only having 4 angles, although that usually worked)
    improved color features, including integration with SpeedGrade and redesigned Three-Way Color Corrector effect
    improved workflows with other applications in Adobe Creative Suite, as well as with Final Cut Pro and Avid software
    faster Adobe Media Encoder, redesigned to make authoring for multiple outputs and mobile devices easier (batch processing was added with CS4, but it wasn't until CS6, with other enhancements that I really worked it)
    enhanced Adobe Encore for creation of DVDs, Blu-ray Discs, and web DVDs (Bluray chapter playlists finally; I have used the flash output, which has gotten better at each step)

  • Any opinions re Avast vs ClamXav?

    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.
    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.
    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. OS X 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 presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
    5. XProtect, Gatekeeper, and MRT reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always 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 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, or that does something inherently untrustworthy. How do you know what 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 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" are in this category, though not all are necessarily harmful.
    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.
    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.
    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.
    Follow the above guidelines, 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 from malware.
    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. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. 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.
    8. 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.
    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 is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, 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. Nothing can lessen the need for safe computing practices.

  • Opinions about MHP solutions (head-ends, middlewares) ...

    I am not satisfied with MHP solutions I use at the moment.
    Thus, I would like to know other opinions about MHP systems they use (bad or good).
    May be somebody can reasonably suggest some STBs with MHP middlewares and reliable and stable working head-end systems. I am not able to try out a number of MHP systems available on the market due to financial reason.

    Thanks, I think that might be the key here for me....
    When I created the .swf in Flash CS4 I imported the .flv files as "load with external playback component", which seems to reference the oringal .flv files. Moving them or renaming them locally on my computer would render the .swf non-functional for movie playback locally...so YES I certainly do need .flv files for my .swf to reference as the movies are not re-encoded into the published .swf  I do see an option to do this however so it is food for thought on if this embedded method may be better in my situation.
    The thing remaing for me to fix now seems to be how to properly reference the .flv files on the remote server when they and the properly configured .swf file are all uploaded.  I see how I can change the .flv source in the properties window within Flash but I will have to do a bit of testing to make sure that it follows a logical and working path when uploaded to my server.
    Hope that all makes sense...if anyone has any input on how best to finish this up or suggest on if I am on the right path I'd love to hear from them!
    Thanks for the help, btw.

  • Opinions about this PSU

    Hi everyone!
    I want to know opinions about this PSU, a Topower True 320W, it cost a half than an Antec True 430, and has the same values for 3.3, 5 and 12v. Here are the details
    http://www.topower.com.tw/home/atx12v_320p4.htm
    For what I've seen on THG website, seems to be a good one.

    Efficiency 70% minimum at 115 VAC, 320W output
    Note: I'll use it at 230 VAC, I don't know if this will change any values of the above.
    Thanks in advance

    Stilup is right. Skimping on a power supply will only bring you more headaches than it's worth. Buy a Good brand name supply 400+ watts, and you will never run into tons of problems that others have, trying to run a hi power system with a $29.95 power supply. Every time you up the cpu ,you need more power. Bigger video card? more power. Add a drive? more power. If you buy a marginal supply in the beginning, you may get it to run your system, until you add something. I have seen hundreds of posts that when they finally divuge what the specs of thier supplys, it is painfully clear what the problem is. All my systems run at least a 400+watt supply with at least 220 combined watt. The exception to this rule, is True power supplys, that supply each single rail seperately ,so the combined thing doesn't apply. BD51

    (Classic still works, but I need it to boot in OS 9.)
    Any clues about what the Leopard installer might have done to my machine that rendered OS 9 boot unusable? (And what can I do to fix it?)
    Details:
    G4 Gigabit Ethernet
    Boot ROM version: 4.2.8fl
    Accelerator card added: 1.6 MHz
    1.5 Gig Ram
    I have erased the partition that had Leopard installed on it.
    I zapped the pram.
    In Open Firmware, I "reset-nvram", and then "reset-all"
    I tried to reinstall G4 FW Update 4.2.8, but that must be done when booted from OS 9, and of course, that's the problem: it won't boot into 9.
    I tried restarting from 9.2.1 DVD.
    I tried restarting from an external firewire drive containing OS 9.2.2.
    I tried moving a fresh OS 9.2.2 system folder into an empty partition on an internal hard drive. (Partition was created WITH OS 9 drivers installed.)
    All attempts to boot into OS 9 give me the same results - grey screen - no spinning beach ball, no icons or logos - just a blank grey screen.
    This machine still works fine in OS 10.3 and 10.4, and it worked fine for many years booting into OS 9, until I installed Leopard, and I haven't been able to boot into OS 9 since then, although I have done considerable research online and tried many things.
    I have since learned that this machine does not support Leopard - 10.5. Fine, but how did it break 9.2.2?
    Any help greatly appreciated.

    Thanks for checking in, BDAQua.
    Problem solved.
    In the docs that came with my Powerlogix accelerator card, I found this sentence buried:
    "If you reset the PRAM, the NVRAM code for OS9 compatibility is cleared, so you will have to boot from the Firmawre Update CD and perform this process again in order to boot in OS9."
    The "process" it's referring to is the process of setting up the NVRAM for booting into OS9 from the CD.
    Fortunately, I was able to find the disk, and it worked as expected. I can now, once again boot into OS9.
    Conclusion: My (unadvised) attempt to load Leopard on this old machine apparently reset the PRAM on the accelerator card and cleared the NVRAM code for OS9 boot. Although I did attempt to reset the NVRAM via Open Firmware, it did not reset it on the accelerator card.
    So, thank you BDAQua, for your "Ah yes" . . . that's all I needed to steer me in the right direction.

  • I just got a notice to update my firefox to 4.0 and when I downloaded the new software it indicated: that I can't open the application "Firefox" because it is not supported on this architecture. Any ideas about what might be wrong and how to fix it?

    Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
    If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html

  • I have a MacBookPro6,2 and would like to connect an older Dell flatscreen, model L17BNS. I would welcome any information about the type of cable I need and any settings I might need to change, etc. Thank you for your time.

    According to:

    It has DVI ports.  This means you are best to use an adapter that supports DVI.  Note there is no audio that carries over DVI.  What you need is a mini-Displayport to DVI adapter, and the proper DVI cable. Since Dell doesn't have the specs, you'll need to tell us if you have pins or holes, and how many are grouped.

  • Any idea about the pricing of the hardwares for Oracle 10g RAC?

    Hi,
    If I go for 2 nodes RAC using Dell servers and Disk array, any ideas about the prices? (just for the hardwares.)
    Thanks.
    Regards,
    Jason

    It's all about the shared disk(s).
    If you are only ever going to use two (2) nodes a SCSI JBOD solution is cheap. (practical too with ASM as the cluster filesystem / volume manager)
    More than 2 nodes, you step up to certified NFS, iSCSI or FC/AL connected storage. More expensive, faster, more flexible.
    The computers are the cheapest portion of the cost especially with multiple core multiple cpu 64bit linux based servers being so inexpensive.

    Can you start Firefox in [[Safe mode]] ?
    You can also do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
    Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
    It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
    You can initially skip the step to create a new profile, that may not necessary for this issue.
