Are there any JCOP functionality to measure performance within card ?

Hello,
We are trying to measure some functions performances. Bu we dont have any specific tool for that.
We made some tests with PC applications, but it is not precise(as you know there are some scard library delays).
Is there any internal card(jcop) functionality to estimate the time interval for our card functionalities, or do you you have any other suggestions ?
Thank you in advance.

Hi,
Given a card does not have a real time clock it is not really aware of time in this way and adding a measurement would affect the performance as well (note there is some timing in the crypto chip to help protect against certain attacks, but this is not exposed to the JC API).
The best you can do it measure the time before and after transmitting an APDU at the lowest level possible. It is safe enough to assume that the PC/SC overhead is going to be consistent for the same amount of data. You could even benchmark just sending data to the card without doing anything with it to measure the time for transmitting your data. This is not generally needed as you are interested in the performance as perceived by a client application or a user and this transmission overhead is a part of that as well.
Just my $0.02 anyway.
Cheers,
Shane

Are there any general guidelines/algorithm to perform arc/circular motion?

My system consists of a PC with a IEEE488.2 from NI that connects to 2 Newport MM4006 controllers, which, in turn control a high-precision stage.
I would like to know if you can provide me with any guidance/algorithm to learn about programming arc/circular motion.
I learned that there is advanced feature not included in my version such as Draw Pictures and Draw circles under Pictures. Are these features merely for plotting on computer screen and NOT actually for commanding the controllers to physically build arc or circles.
Any advice or suggestion for arc or circular motion?
Thanks

You are restricted to the types of moves which are allowed by your Newport MM4006 controllers. Some controllers have built in advanced trajectory generation just for arcs, curves, and countoured moves (such as the PCI-7344). Other boards are restricted to a series of straight line moves. The tools you are given to perform an arc depend on the functionality of your controller. If you can only do straight line moves, you'll need to develop an algorithm which will break up an arc into a series of many small straight line moves. I am not aware of any such already built algorithms here.

Are there any plans to add Measuring and Rotation tools into Adobe Reader for iPad. Currently using V11.2.0 (86952)

We need to provide our planning officers with io site access to plans via iPads. Whilst they can view the plans in .pdf format via Adobe Reader, they need to be able to rotate and measure whilst on site.

For Adobe Reader, the stated features are highly unlikely but you might want to fill the feature request form at: Adobe - Feature Request/Bug Report Form

Are there any known issues with Adobe Edge Animate and Yosemite? Experiencing performance issues since upgrading OS

Are there any known issues with Adobe Edge Animate and Yosemite? Experiencing performance issues since upgrading OS. Animation I was working on that had been performing in browser fine suddenly stopped working, and was not related to any action I had done at that point. Also was working in it today and program stopped responding to key board short cut commands.

I am having a whole slew of odd interface problems with a fresh 2014.1.1 on a fresh macbook pro with latest Yosemite. Program locks up, cursor selections don't show, things disappear. I have a mac mini also and the program runs fine on it. Is there possibly something related to the solid state hard drive in new macs?

Basic troubleshooting steps outlined in the user guide are restart, reset, restore from backup, restore as new device. Try each of these steps until your problem is solved. If these steps fail to solve your issue, then you'll need to bring your phone into Apple (or an authorized service provider in your area) for evaluation.

Are there any hot fixes or releases due soon?

It's been a while since I've seen anything released from the update centre. Are there any fixes due for release soon?
Despite several months, a few hot fixes and the JSC2 Update 1 release, JSC2 doesn't seem to have improved all that much since the initial release.
The main issue for me at the minute is performance. I know this has been discussed several times on this forum, but there is very little information on when we might see a release that starts to address this issue. I realise that the issue is complex and probably covers many functional areas of the app, so a hot fix or two will not address the problem. However, at the minute working with JSC2 on a medium sized application is unproductive and is becoming almost unusable. For example, even minor code tweaks or property changes completely lock the IDE for around 30 seconds and send my CPU usage to 100%. The thing is that, functionally JSC2 is excellent. This is the way I want to be building my JSF applications and I'm very grateful to Sun for making it available for free. If it wasn't hampered with these performance issues I'd be knocking out web apps in no time at all but unfortunately, as it stands now, it is almost a hinderance. I have some new projects coming up where I would like to use JSC2 but I cannot recommend it on the grounds of productivity.
When can we expect something to be released that starts addressing performance? When can I start recommending JSC2 again?

As per previous posts, complete agreement.
I have built a production system in-house for a large company using JSC. I had to get my machine upgraded to 2GB just to get some usuability but it still needs a few jsc re-starts and appserver restarts through out the day.
Functionality wise, JSC is such a winner and the guys at SUN have indeed did a great job. I come from a VB environement for the last 12 years, so having a rich web client tool was high on my priority. But if I am to try and preach to the rest of the J2EE guys here, the performance issues really need to be addressed. They are used to Eclipse and I don't need to go on about how good that tool is. If any other company gets JSF to work under Eclipse the way JSC does, I would have no hesitation in using that tool.
I hvae tried some of the Eclipse based JSF IDE's and they don't even compete with JSC in terms of ease of use and putting apps together. But they do not lock the machine for 30 secs when I click a property or right click on a component !
I have been one of the champions of JSC from the start and I still am. The system I wrote has near 300 users and is working fine with not one
problem in 3 months. If this performance problem can be beat, JSC will set the standard for GUI development for years. If not, then it will be consigned to the nearly made it bin.
To the guys at SUN:
After all the time and effort you have put into this product, I'm sure there is no overnight cure for the problems. I am sure you are working on the problems. For me, I don't care about any new Ajax components, etc in the updates. If the next patch gets JSC even working 50% better performance, I will be a happy man. Then I can go and try to convert the unimpressed.
if not, then I will be forced into a corner to use IDM RAD tool for JSF development, of which I do not want to do. My company has an IBM affiliation, but I like to use the best tools for the job.
Overall, impressed by JSC but the final hurdle has not been jumped.

LOTI.

Are there any applications that cleans up your macbook ?

I bought a macbook a 2 months ago.
I am wondering if there are any applications that cleans up my macbook. Like the ccleaner for windows.
Are there any ?

Ccleaner on Windows has a few functions:
1: Repairs the Registry
2: Cleans the caches
3: Secure Erases free space on the drive / deleted files.
OnyX for OS X.
1: OS X doesn't have a Registry to bork, but other things like Preference files, caches etc, can.
2: OnyX can clean the caches and check for corrupted Preference files, rebuilt ds_store files and other things, basically clean out all the automated stuff designed to make the computer faster so it can rebuild it in case it gets borked or may contain content you rather wish it didn't.
3: OnyX can Erase whats in the Trash, but not wipe free space on the drive, Apple's provided Disk Utility has a feature to to that.
So if your looking for something to clean your Internet tracks on OS X, first use the browser cleaning aspects, then OnyX cleaning, then a reboot to clear the OS X DNS cache then a Disk Utility > Wipe Free Space.
These features are not automated or intertwined with Firefox add-ons like Click2Clean is with CCleaner on Windows. You'll have to perform it manually.
http://www.titanium.free.fr/
Another option for totally cleaning one's system faster on OS X would be to use the free VirtualBox to run a free distro ISO of Linux (Ubuntu, Mint, MacBuntu etc) in OS X. Then once the distro is setup in the virtual machine, save a snapshot of this OS state to revert back to after browsing potentially malicious sites in Firefox (in Linux)
Reverting on takes only a few seconds, instead of the painfully long time OnyX can take, and ensures everything is included for removal, of course a DU free space wipe would be necessary for completeness.

I have an imac G5 with a power PC chip running os 10.5.8. and using safari 5.0.6. are there any security threats i should be aware of? s there a

are there any security concerns using my PPC imac g5 running OS 10.5.8 and using Safari 5.0.6?

You could use a browser that does not use Flash or Java, as a safety measure when visiting sites; the Safari browser has no support or recent updates. TenFourFox v 24 is fairly good, and uses later Mozilla code, is compatible with powerPC computer limitations. SeaMonkeyPPC has a similar code, but acts a little different; and there still is iCab, a good browser that will run free, but asks you get a $20. license.
The Safari browser can be used to set a different browser up as system default, so it won't launch and open attachments or web pages; it has a setting in its preferences where you choose another browser as default. As I have four or five browsers and one dedicated to gmail (launched as signed-in, through notifier) that is how I've used the default, otherwise mine are all in the Dock.
There is no new upgrade for Adobe Flash plugin player, etc; but the one in their site for vintage is still available at getflash player at Adobe. Most prompts online are to get you something else, even adware loads up from some not-so-clever efforts to get people to install junk. So go to the source. Someone wrote a patch that is supposed to allow a later version of Flash player to work in older 10.5.8 PPC Mac, but I have not tried it.
The thread of security is mostly based on the user and their caution to avoid odd free software and also avoid some sites that try to get people to load cleanmymac or genieo, or other adware malware voluntarily. Those are troublesome and hard to remove, and can waste processor cycles, slow the computer & mess it up. Mostly from a browser the adware issues arise. For those you see The Safe Mac and read up on the adware removal guide, among others linked on the page: http://www.thesafemac.com/arg/
So anyway, there is really nothing new on the face of it for obsolete OS X systems users.
Good luck & happy computing!

Nas on airport extreme not recognized by time machine. same nas was previously used as time machine backup on different airport extreme. are there any configuration files that i can delete to fix this problem ?

Time Machine has been working just fine, but in the last week or two it has given up the ghost. I reset the connections to the drive, and it will basically save a few bytes of data and then hang.
Although Apple originally announced, prior to the release of the first 802.11n AirPort Extreme Base Stations (AEBSn), that it would support Time Machine backups to AirPort Disks, they removed that option before they did finally release the base station for sale.
Since then, Apple has posted (as you have noted) that they DO NOT support Time Machine backups to AirPort Disks. As far as I know, they have not changed from that position and those who do these backups find that they become corrupted over time. Sorry, but it sounds like you just confirmed that for yourself.
1) Has one of the recent updates either on the AE (firmware) or OSX disabled this function?
No. Again, this feature has never been supported by Apple for every generation of AEBSn released.
2) Are there any changes I can make to get this working again?
If your data backups are critical to you, then you will want to use a different solution for your Time Machine backup destination drive strategy. I would suggest that you connect your WD My Book directly to your Mac in the mean time.
Your other options would be to either use a Time Capsule (which interestingly does support TM backups to AirPort Disks) or a non-Apple solution like the Drobo FS or HP MediaSmart server.

Are there any known issues when using PSE 13 after installing Apple's recent 10.10.3 Combo update for Yosemite?

I've had Yosemite for some time and bought/installed PSE 13 afterwards.
In the last few days I upgraded to Yosemite 10.10.3.
As a PSE 13 novice I've been working my way through "Adobe Photoshop Elements 13 - Classroom in a Book". Working through the exercises I've found my iMac is sometimes taking longer to process the functions I'm using than prior ro the 10.10.3 upgrade. E.g., using the Healing Brush tools, Straighten Tool etc.
I've struggled with Apple's upgrade and had to re-install my machine from a previous Time Machine Backup and so I was wondering:-
Are there any known issues with PSE 13 post 10.10.3 upgrade?
Are there things I should be concerned about in the future before accepting an OS X upgrade?
Thanks,
Andy

No, no known issues. However it's a good idea to always delete preferences after OS X system updates.

Are there any tools from NI can generate the pass-through layer (IVI class driver) for IVI class specific driver?

IVI class driver (layer) will provide interchangeable feature for a IVI class specific driver. It would work as a pass-through layer and finally make calls to the IVI class specific driver. Since there could be a lot of functions to be passed through. Are there any tools from NI (Labwindows/CVI or Labview) can do this ?
Thanks a lot.
BTW: the IVI class specific driver interface is generated from Labwindows/CVI tools.

Hi Chris,
Yes, I did. To support interchangability, from my understanding of the IVI specs, there should be another layer IVI-C class driver on top of this IVI class specific driver. As in the IVI‑3.1: Driver Architecture Specification:
Although IVI‑C class drivers export inherent,
base, and extension capabilities, they do not actually implement them. Except
for a few inherent functions and attributes defined exclusively for class
drivers, class driver functions and attributes provide a pass‑through layer to
the IVI‑C specific driver. An IVI‑C specific driver is responsible for
implementing the operations of functions and attributes and for communicating
with the instrument. The IVI‑C specific instrument driver contains the
information for controlling the instrument, including the command strings,
parsing code, and valid ranges of each instrument setting"
So where is this IVI-C class driver and how is it created and communicate with my class specific driver?
Thanks a lot.
Cheers,

Are there any tools for data encryption and decryption ?

Encrypting a password is itself not secure. Anything that can be encrypted can be decrypted. That is why Oracle itself DOES NOT encrypt passwords.
Surprised??
Here's what Oracle does with passwords, and what others should be doing if they have to store them.
When the password is created, the presented password - clear text - is concatenated with the username. The resulting character string is then passed through a one-way hashing function. It is that hashed value that is stored. Then when a user presents his credentials to log on to the system, the presented credentials are combined and hashed in the same manner as when the password was created, and the resulting hash value compared to the stored value.
