• Remote Control Home PC from Corporate Work PC

  - by muncherelli

  Here is my situation: I am currently on a Windows XP workstation at work. I have an android tablet that I use to splashtop into my home PC. I would like to be able to use my work keyboard and mouse to control my home PC while I am splashtop'd into it using my tablet. My work PC is on a corporate LAN, and not on the same network as my tablet. The company I work for provides wifi for personal devices, but they are not accessable to the internal network. I thought about going the Synergy route, however that would require my home PC to be able to connect to my work PC which isn't really possible. The opposite would work though, if I could reverse connect the server to the client, but the Synergy software doesn't really support that. I do have a couple linux boxes running at home, so I can ssh into my home network and tunnel ports via SSH if needed. With what I have, how can I accomplish seamless keyboard and mouse sharing between my work PC and either my home PC or my android tablet?

• Error when installing ubuntu-zfs

  - by ubiquibacon

  I'm switching from FreeNAS to Ubuntu 12.04 LTS. After a vanilla install of Ubuntu has been completed I run the following commands in the order shown to install ZFS: apt-get install python-software-properties add-apt-repository ppa:zfs-native/stable apt-get -y -q update && apt-get -y -q upgrade apt-get install ubuntu-zfs When the last command is run ZFS is installed and seems to be working correctly... mostly (more on that later). However, when the last command is run I get this error (full log here): configure: error: *** Please make sure the kmod spl devel <kernel> package for your *** distribution is installed then try again. If that fails you *** can specify the location of the spl objects with the *** '--with-spl-obj=PATH' option. What is this error and how do I fix it? Now I said mostly earlier because my pool's don't auto mount when the server restarts the way they should. All my reading (mostly from this page) indicates that mountall should just take care of the mounting. I have followed the instructions on that page and I cannot get mountall to work correctly. My pools will only auto mount on restart if I edit /etc/fstab or change the ZFS_MOUNT and ZFS_UNMOUNT options in /etc/default/zfs.

• Is there a program that compares image files and reports if they are exactly the same pixel-wise?

  - by Nathaniel Drake

  I'm making a regression testing suite for some rendering software. I need to be able to load an image file (PNG or TGA, ideally) and compare the pixel values to a standard approved image. I'd like it to be command line driven too, so I can make a batch file to run all the tests. All the compare utilities I have found so far either show differences (I just need it to fail if they are different) or compare all the bytes, meaning that meta-data will trigger a fail. Anyone got any suggestions? I am not a coder, and can only barely cobble a batch script together. Thanks for any suggestions.

• Open Source Projects for Beginning Coders?

  - by MattDMo

  After working as a molecular biologist at the bench for many years, I lost my job last year and am thinking about a career change. I've been using open-source software and doing Linux system administration since the mid 90s, and have written/improved some small shell/Perl/PHP scripts, and am very comfortable building from source, but never progressed to creating non-trivial programs de novo. I want to move to actually learning real programming skills and contributing back to the community, with the possible eventual goal of getting into bioinformatics as a career in the future. I'm a stay-at-home dad now, so I have some time on my hands. I've done a lot of research on languages, and have settled on Python as my major focus for now. I'm set up on GitHub, but haven't forked anything yet. I've looked around OpenHatch some, but nothing really grabbed me. I've heard the advice to work on what you use/love, but that category is so broad that I'm having trouble finding any one thing to get started on. What are your suggestions for getting started? How do you pick a project that will welcome your (possibly amateurish) help? With a fairly limited skill set, how do you find a request that you can handle? What are common newbie mistakes to avoid? Any other advice?

• Can a 32-bit RHEL4 userland work with a 64-bit kernel?

  - by James

  Is there a way to change an i386 RHEL4 machine to run an amd64 kernel, but ensure that it still builds software into same i386 binaries? On Debian this seems quite straightforward: just install an amd64 kernel (worst case, build one like this guy: http://www.debian-administration.org/users/jonesy/weblog/1) and prefix everything with "linux32". Then everything that considers uname -m will be unchanged, I just need to handle the few cases that consider uname -r. What is the Red Hat equivalent? Is the only way a full 64-bit installation on another disk and then chrooting back to the 32-bit system before anyone builds anything? (Even the best examples of that seem to be Debian-based.) Background: We make a large system that runs on (a variant of) i386 RHEL4. However, some of the larger RHEL build machines now have enough RAM that they might benefit from going 64-bit (for the kernel and maybe some of the bigger build steps). Our build system doesn't support cross-compilation.

• Which WordPress plugin adds support for Java syntax highlighting? [closed]

  - by Bozho

  In wordpress.com-hosted blogs syntax highlighting is working, but on a newly privately installed WordPress blog it is not. So I assume there is a plugin for this. I tried wp-syntax and bbcode plugins - no success. So, which is this plugin, that allows programming language code to be highlighted: [code language="Java"] public class SomeClass {..} [/code] Update: I'm talking about the WordPress software, not the wordpress.com service. I was just giving an example (wordpress.com) of what is to be achieved.

• Is there a way to disable specific Spybot Immunization rules?

  - by Iszi

  I've been having problems using a desktop sharing application, which I've traced to the Immunization protections applied via Spybot S&D. Specifically, the problem has been narrowed down to the rules in the \SOFTWARE (Plugins) categories under the Internet Explorer groups. Once I disable these Immunization categories, everything in the application works fine. Each of these categories appears to include ~900 protections on the system. I suspect that the root cause of my problems could be narrowed down to just one, or perhaps a handful, of the settings that get applied in these categories. However, I can't find any options in Spybot S&D which would allow me to drill down to the individual protection rules and choose which to enable or disable. Is there something I'm missing, or is this not a feature available via the GUI? If it's not strictly supported in the application, is there a way to work around it by manually editing some of its files or registry settings? Spybot S&D version: 2.2.21.0 Spybot Start Center version: 2.2.21.129 Windows Ultimate x64

• How to route traffic through a VPN tunnel?

  - by Gabriel

  The problem with our server is that we need to use the bug ridden and awful AT&T network client, which causes our server to bluescreen once per 24 hours. Does any one know how to (or has a good guide) quickly set up a workstation running Windows server 2008 R2 as a proxy server. So this spare workstation would run AT&T and would act as a bridge between our server and the server that can be connected to only via the AT&T VPN software. And this way our own production server would not crash so often (or not at all) and the workstation can happily crash whenever it wants to.

• How to tunnel port 25565 through SSH?

  - by user62389

  I want to play a game which is hosted on port 25565 (minecraft!), but my university firewall does not allow this port. I have a dedicated server running linux not too far from uni, so I think there's a way to tunnel through it (but I've never done this before and have no knowledge/experience of tunnelling) It would probably be slow, but it's better than not being able to play at all. Is it possible to do using only SSH, or do I need other client/server software? My server has OpenSSH installed. Also, the computer I'm using to play the game is running Ubuntu. I've tried searching but there seem to be so many different solutions to different types of problem =/

• Time difference between servers after disaster recovery

  - by Sandokan

  We are running an old training system based on Windows Server 2003 and XP-clients. The solution is rather simple with four servers, two of them beeing DC:s. Everything is preconfigured and that goes for backup scheme as well. The backup software is Symantec BackupExec 2010. The scheme is a standard GF-F-S routine with full backups running once a week on Sundays. The other six days run differential backups. Now let's say in a worst case scenario, a server crashes on Saturday and we have to restore it from backup. The last backup will then be six days old and thus it will come online with six days old configurations. Will this pose a problem for the other servers or will the recovered server "get in line" eventually?

• Coordinate spaces and transformation matrices

  - by Belgin

  I'm trying to get an object from object space, into projected space using these intermediate matrices: The first matrix (I) is the one that transforms from object space into inertial space, but since my object is not rotated or translated in any way inside the object space, this matrix is the 4x4 identity matrix. The second matrix (W) is the one that transforms from inertial space into world space, which is just a scale transform matrix of factor a = 14.1 on all coordinates, since the inertial space origin coincides with the world space origin. /a 0 0 0\ W = |0 a 0 0| |0 0 a 0| \0 0 0 1/ The third matrix (C) is the one that transforms from world space, into camera space. This matrix is a translation matrix with a translation of (0, 0, 10), because I want the camera to be located behind the object, so the object must be positioned 10 units into the z axis. /1 0 0 0\ C = |0 1 0 0| |0 0 1 10| \0 0 0 1/ And finally, the fourth matrix is the projection matrix (P). Bearing in mind that the eye is at the origin of the world space and the projection plane is defined by z = 1, the projection matrix is: /1 0 0 0\ P = |0 1 0 0| |0 0 1 0| \0 0 1/d 0/ where d is the distance from the eye to the projection plane, so d = 1. I'm multiplying them like this: (((P x C) x W) x I) x V, where V is the vertex' coordinates in column vector form: /x\ V = |y| |z| \1/ After I get the result, I divide x and y coordinates by w to get the actual screen coordinates. Apparenly, I'm doing something wrong or missing something completely here, because it's not rendering properly. Here's a picture of what is supposed to be the bottom side of the Stanford Dragon: Also, I should add that this is a software renderer so no DirectX or OpenGL stuff here.

• How to take a CSS animation from a browser, and export a GIF of it?

  - by Truth

  I have the following CSS3 Animation going on: http://dabblet.com/gist/2884702. It's basically a simulation of a mirror rotating on its x-axis. Now, I wish to present that in a PowerPoint presentation. Since PowerPoint doesn't have the webkit engine, I want to extract an animated GIF image of that animation, and embed it into my presentation. The problem? No matter what I've tried, I couldn't make a reasonably smooth animated GIF. I've Googled and found many free software which claim to do the job, tried several, none worked as expected. I've tried IrfanView, same issue (also their site makes me want to vomit). So, is there a solution? Or am I doomed to not be able to display it?

• Bacula vs. BackupPC

  - by chronoz

  I have been googling about the differences between them. Bacula has lots of roles BackupPC is easier to configure Bacula works with agent, not rsync (great for Windows backups) It seems that Bacula is most often compared to Amanda though, while BackupPC seems a perfectly lovely and popular backup distribution to. I currently backup my servers with rsnapshot, but I am looking for a professional scalable solution that could also back-up 50 hosts without problems. Preferably a solution that can offer bare metal restores for my Linux servers. I am not looking to reinstall the exact same version of Plesk, the software, etc...

• Web Folder size/quota reporting tool?

  - by nctrnl

  I am currently using a Visual Basic script to determine how big the web folders are and what quota is decided for each folder. The quota is in no way a physical limit, just a value inserted by me to decide whether a user is using too much space or not. The script does the job quite neatly and sends an html file by mail on a regular basis. The problem is that it's such a hassle to insert new quotas since I have to fiddle around with the code. A central "control panel" with an overview and ability to insert new quotas would be more suitable. Is there any software that can do the following: Scan specified folder/subfolders Report the file size and present it in some sort of interface (could be a php/mysql solution) Ability to specify a quota and see the difference value ? It is really important that the quota handling is made simple so that some non-technician can handle this.

• What is a Coding Dojo?

  - by huwyss

  Recently i found out that there is a thing called "coding dojo". The point behind it is that software developers want to have a space to learn new stuff like processes, methods, coding details, languages, and whatnot in an environment without stress. Just for fun. No competition. No results required. No deadlines.Some days ago I joined the Zurich coding dojo. We were three programmers with different backgrounds.We gave ourselves the task to develop a method that takes an input value and returns its prime factors. We did pair programming and every few minutes we switched positions. We used test driven development. The chosen programming language was Ruby.I haven't really done TDD before. It was pretty interesting to see the algorithm develop following the testcases.We started with the first test input=1 then developed the most simple productive program that passed this very first test. Then we added the next test input=2 and implemented the productive code. We kept adding tests and made sure all tests are passed until we had the general solution.When we improved the performance of our code we saw the value of the tests we wrote before. Of course our first performance improvement broke several tests.It was a very interesting experience to see how other developers think and how they work. I will participate at the dojo again and can warmly recommend it to anyone. There are  coding dojos all over the world.Have fun!

• MLGPO for Windows Server 2003 R2?

  - by 5graeham5

  Is there something like MLGPO (Multiple Local Group Policy Objects) for Windows Server 2003 R2? I have a 2003 Terminal Server that isn't part of a domain/AD and I'm trying to set local group policies which applies only to certain users and/or groups and the policies differ between those entities. I wanted to avoid using the file permissions trick for on C:\WINDOWS\system32\GroupPolicy as that's an all-or-nothing approach. I can't upgrade this box to Windows Server 2008 as the software used is only supported and only works on 2003. Are there any third-party tools to achieve this?

• Serious voltage and temperature problems

  - by James Willson

  My computer has been acting up when I play games so I wanted to look into why. Issue 1: GPU Temp According to afterburner and speedfan my 8800GTX idles at 90 degrees and then when playing games shoots up to over 110C which is when my graphics basically starts to give rendering issues. Issue 2: CPU Temp Speedfan is saying my CPU temp is 83C idle but when I look at core temp it says core0 is at 35C and core1 is at 33C. Issue 3: Voltages This is what speedfan is saying for my voltages: Vcore1: 1.01V Vcore2: 1.90V +3.3V: 3.31V +5V: 4.95V +12V: 0.51V -12V: -16.80V -5V: -8.43V +5V 5.13V Vbat: 3.25V Vcore: 3.00V +3.3V: 3.20V These voltages, for lack of a better word, look f*cked. With all this happening, the computer runs ok under normal use. Is the software giving out incorrect readouts or instead should I immediately move the computer into another room before it explodes? P.s I would like to add this is a stock system. EVGA 8800GTX, E6850 CPU, 800W PSU

• You are or will be a laid off programmer - what do you do a year ago, right now, tomorrow, and next week?

  - by Adam Davis

  Many programmers, software engineers, and other technology professionals are out of work, facing layoffs, or are unprepared for layoffs though they feel secure right now. What should every programmer do right now (even if secure in their current job) to prepare them for layoffs down the road? If your boss came to your cubicle while you read this and laid you off: What would you do immediately after? What would you do tomorrow? What would you do next week? It obvious that one should always have an up to date resume, always get recommendations from people when they see you at your best (not when you're looking for a new job), etc. What are the things, step by step, that every programmer should do (or should consider doing) long before they are laid off, when they're laid off, and shortly after being laid off? This is a question with many possible facets. While I want to encourage discussion to center around programming career based answers, please reconsider before downvoting someone because they're thinking in terms of how they're going to prevent going into debt. Bonus catch-22 type question: You can study a new language or technology while out of work, but most places want you to have more than 1-2 months experience in a working environment, not just from a learning exercise. Is it worthwhile to place a priority on new (ideally in demand) skills, or should you instead hone existing skills?

• Windows 8.1 touchpad three-finger-multitouch gesture gone

  - by THEVAN3D

  Couple of days ago, i installed the Windows 8.1 Pro WMC and all of a sudden the touchpad gesture, which worked like a charm back in Win 8.1 preview, Win 8 and even Win 7, just stopped working. I am talking about the "Three Finger Flick" feature, which is used to go back and forward in folders and/or internet browsers at first i didnt even have the left edge pull feature, but then i added some values in this key into regedit, and now i have it [HKEY_CURRENT_USER\Software\Synaptics\SynTPEnh\ZoneConfig\TouchPadPS2\Left Edge Pull] I Googled that, i didnt know what to do by myself and i dont know where to write and what to write anything in order to get the three finger flick back too I installed various versions of drivers starting from about version 15 to the version 17.0.8.0 (the one that i currently have), and even though i have all the other gestures, taps and swipes working they are not in the device settings, there is no multitouch gestures in device settings so thats why i guess i have to write something in regedit, but again, i dont know what to write, and where to write. please help me if you can

• Oracle Virtual Desktop Client with USB smart card reader

  - by wim.coekaerts

  I have my Sun Ray thin client at home which I use religiously, I use a Sun Ray 3i at work as my main desktop and just always take my smart card home and happily continue with the hot desking feature. We released a software version of the Sun Ray client called Oracle Virtual Desktop Client (OVDC). There is a version for Windows, Linux and Mac OS X. I have a minimac at home and I installed OVDC on it, which of course works great but since I like to re-connect to my session that I use at work, I wanted to try out the external usb smart card reader feature. I ordered a cute, low cost device online and tried it out. As expected, it worked out of the box without -any- configuration. I took the device, plugged it into my minimac, started OVDC, plugged in my smartcard and I got the password screen (screensaver) to get into my sun ray session on my server at work. Nothing new here, this is a feature that's been in the product but I had never tried it before and it works out of the box and is super easy and I just felt like sharing :-) Here are a few pictures : (1) login screen (2) smart cardreader without card (3) password screen (4) smart card reader with card

• what languages are good selling points on resume? [closed]

  - by Thomas Galvin

  I have a good amount of experience with C# and Java at the moment but after education and whatnot I wish to be able in more than just 2 high-level, comparatively limited languages, and from what I've seen languages like C(++) or PHP are in demand at the moment. I've thought about learning the following: C. Very standard, lightweight and available on everything. However very old and mostly procedural. C++. Standard like C but I've read in some places that it encourages bad programming design and use of dodgy libraries - but similar things have been said about C too so I'll take that with a grain of salt. D. Quite new but looks promising, but will it be relevant or applicable in the future though? PHP. With the internet becoming ever more important I think this might be the one to go with, but the code itself isn't very intuitive. CoffeeScript (or plain JavaScript). With Microsoft's new idea of HTML5+JS for everything under the sun this doesn't look like a bad choice. However things do change and I wish to be primarily a software dev, not web dev. So out of the above list, or any others that you could suggest, what would you say I should begin to focus on? What is your opinion on staying with C#?

• What is the lease irriating printer manufacturer?

  - by aireq

  Currently I have a Lexmark all in one printer/scanner which has some of the worse drivers I've seen for a printer. The installation takes forever. Then once it's installed the printer will only work if I keep the "Lexmark Productivity Studio" running in my system tray. Then later after I've scanned something 99% of the time the "Save to PDF" button doesn't do anything when I click it. It is also a wireless printer, but of course the only way to set any of the wireless settings is during the driver setup. So if my WEP key changes then I have to go off and reinstall the entire printer driver. Lately I tried refilling one of the ink cartridges with a key I bought off amazon, and now both the printer and the drivers keep complaining about being out of "Official Lexmark Ink" This comic from The Oatmeal pretty much sums up my feelings about consumer printers and their drivers. This question is, of course, pretty subjective but I'd like to know what (if any) consumer printer brands actual provide quality drivers and software with their printers.

• Missing management console for Symantec Antivirus, Corporate Edition

  - by Alex C.

  I work for a small (80 employees) non-profit organization. We have a Windows network with a domain. The file server is running Server 2003. A vendor recently installed Symantec Antivirus, Corporate Edition, ver. 10.1.8.8000. It used to be the case that when I logged in to the file server as administrator, I would see an icon on the desktop that took me to the management console for the antivirus software. I could check logs, statuses of client machines, set policies, etc. That icon is now missing, and I can't find anything relevant under the "Start" menu. There is an entry for Symantec Antivirus, but that only gives me the panel for the client process, not the overall management console for the whole network. I don't want to call the vendor back to fix this (I'm baffled how we lost the icon in the first place). Can someone offer some guidance?

• International Dvorak keyboard doesn't trigger hot-keys

  - by akurtser

  I'm using the Engilsh-Dvorak keyboard-layout; My second keyboard language is Hebrew, which has nothing to do with Dvorak but the hot keys (e.g if I'm writing a document in Hebrew and want to make some bold text using Ctrl+b). The default Hebrew keyboard that comes with Windows (7 and below) has a shift mode which matches each Hebrew character with its matching English QWERTY character ). Obviously I'd want to use the Dvorak corresponding key rather than the QWERTY one, so I created a Hebrew-Dvorak keyboard with a software called Keyboard Layout Manager (KLM) which creates new keyboard layouts DLLs. It works just fine for the shift key, however, Ctrl-key triggered hot-keys (e.g Ctrl+l in FF) are being matched to the corresponding QWERTY key. I've examined the properly working English-Dvorak layout using KLM and in it's "Ctrl+ pressed" view, there isn't any character that's matched to any key but still I tried to encode the Hebrew Ctrl+ pressed keys to work with their matching Dvorak keys, yet it had no effect.
