• A router that supports connecting with 2 different wifi networks

  - by Allan Deamon

  I Have the following setup in one place: We have a small local ISP through wireless. I have a external parabolic antenna, connected to a external usb wifi radio, connected through USB to a desktop old PC. The pc connects do the ISP wiki network, then do a Dial Up (PPPoE) connection through the this wifi setup. This will expand with others mobiles devices to be used. When I need, I take my home wireless router and connect though Ethernet in the PC, which is shares the internet. The problem is that the PC must be always ON and working. I would like to buy a wireless router which could be an AP to the mobile devices, notebooks, etc, as also could connect to the ISP Wifi/PPPoE network. So, this device must: Have one radio with detachable antenna to connect to the external antenna. It must connect as client to a network and then dial up the PPP Have another radio serving as AP (infrastructure) to the local place This can't be very expensive. I found a candidate: ( http://www.tp-link.com/en/products/details/?categoryid=1682&model=TL-WR2543ND ) It have 3 deatachable antennas, working with dual band. Officially, his firmware doesn't support it. My supposition: If internally there is 3 or 2 distinct wlan ports (like wlan0, wlan1), and there is support, i could use a OpenWRT, DD-WRT or Tomato to make this works. It also have 1 USB port, which I cold use to connect my actual USB Wifi card on it instead to the old PC. Another alternative, is a router that can do this out of box, with the original firmware. But I don't think this is a easy thing to find.

• Why are my downloads up to ~1500KByte/sec only, when the ADSL connection locks at 13611Kbit/s?

  - by leladax

  No uploading is going on other than the overhead of downloading which appears to be not high for the abilities of the connection: Only about 30-40KByte/s when the router locks at 1012Kb/s and other direct uploads or uploading overheads can reach more than 100KByte/sec so I don't think it's a congestion at uploading that is doing it. Is there something I miss? Because I assume 13611Kbit/s should be ~1701Kbyte/sec. Is it an overheard at the ADSL level I don't understand? Could it be the ISP doing it? If it's active throttling it can't be on single connections since 2 high speed connections still go up to ~1500KByte/sec. It's not an example on torrents or other complex situations. The tests were on Ethernet, but I doubt the results would be different on wireless. I wonder if the settings of those connections at my end could be doing it, e.g. MTU settings, though I haven't touched the defaults of a common Realtek NIC.

• All FireFTP passwords gone after auto-update

  - by GitaarLAB

  For the last six months (since the Firefox madness started and they keep on taking control of my PC) I'm terrified to touch Firefox. Problem is however, I've been using it in my business (since once upon a time it was a trustworthy application with useful extensions like FireFTP) and that installation (and plugins) holds four years of information. So Firefox continually deletes my important data (by) messing up (or blocking/or worse: auto-updating) my plug-ins, even crashing my computer as a result. Today Firefox killed FireFTP by (again) autoupdating FireFTP without my permission, and I did my best to disable that nonsense in about:config). Result: none of the (over 100) FireFTP accounts can be logged on to, they suddenly all ask for a password. I do not have the time to to find all of the passwords and reconfigure FireFTP again. How can I undo the mess Firefox created once again? That is, where are the passwords, how do I downgrade? As a side-question, how can I make Firefox behave again? I'm the boss of my computer, not them! How can I once and for-all take back control and completely kill every kind of auto-update feature?

• I recently converted my ex HDD from FAT32 to NTFS. now my pc doesn't find or pick up my NTFS HDD

  - by Jason Haniball

  I recently converted my external hard drive from FAT32 to NTFS using the Command Prompt. Everything was working fine, I copied a 7GB file to it and everything worked. The next day I switched on my PC, I couldn't and still can't find my external 1.5TB hard drive by my computer. I have about 500 to 800 GB of data on it that I really don't want to lose. Its a Iomega Seagate Freeagent HDD. Has no switch, it switched on automatically, don't know if that helps.

• How can I play Blu-Ray movies on a PC upgraded to Windows 8?

  - by Rowland Shaw

  How can I play Blu-Ray movies via Windows Media Centre on Windows 8? If I choose the "play dvd" option, I get an error: Cannot Play Disc To play this DVD, you must first install a playback application that supports Blu-ray Disc. [ OK ] However, I have got the HP MediaSmart application installed, which does work (although it's "less than awesome"), so I'm confused why I get this warning?

• Linux Mint loses Window Focus

  - by Chris

  I recently installed Linux Mint 13 64bit with Cinamon Desktop and run into a weird problem. It's about losing Mouse-Focus if more than one Window are open. For Example, I open up Chromium, play around a little bit, and then, if I try to open any Programms from the Taskbar, I cannot click on it. It seems that Chromium won't free his Focus. Another Example, if I open two Windows (e.g. Chromium and a Terminal) and I work with Chromium, then click into the Terminal I get no Focus to it. Sorry, its a bit hard to explain.

• Cloned Windows 7 to new HDD and want to change the drive letter to C

  - by Hoppe

  I used Clonezilla to clone my existing hard drive to a new one I bought. I then changed the BIOS to set the new drive as the first in the boot sequence. I'm pretty sure that I'm still running Windows 7 on the old drive. My old drive is marked as C. Now that I don't have a disk drive any more, how I do I swap the drive letter from J: to C:? I tried to change it in the disk management section of "Manage", but it reports: "the parameter is incorrect".

• Replacing files in a folder structure with files from an unsorted folder

  - by Andrew

  I have over 50,000 PDFs organized into folders in a file called PDFACT. I needed to compress these files so I ran them through Adobe to batch compress them and this worked—except Adobe could only output the files without their folder structure. So basically I have 50,000 PDFs set up in a folder with hundreds of subfolders, and everything was organized. I ended up with one folder with 50,000 compressed PDFs in it, just in alphabetical order. Somehow I need to replace all the orginal PDFs with their compressed copies. Let me give an example: In the folder PDFACT we have the following file: C:\PDFACT\BIG DINNER\BILL\NEWESTBILL.PDF … and in the output folder that Adobe created we have just: C:\COMPRESSED_PDF_FOLDER\NEWESTBILL.PDF This copy is smaller then the one in PDFACT and has the same name but it is just lumped in with every other PDF. The folder structure and subfolders are gone. Is there any way to replace all the larger uncompressed PDFS inside the orginal folder structure with their now compressed counterparts?

• Where does Skype save its chat history & contacts?

  - by user4796

  I'm aware that there is a main.db file that is stored in a Windows directory. On XP: C:\Documents and Settings\<windows user>\Application Data\Skype\<username> But I just downloaded Skype onto my Android and noticed that all chats are sync'd. So to me, this suggests that the main.db file is not the only storage being used (because it is obviously not on my phone). Are contacts and chat history stored in my online Skype account? Does anyone know where I can find more information about this? I read this thread: Does skype automatically save chat history to the cloud? And how do you explain the sync'd chats?

• what type of laptop do I need to run a amd64 or i386 VM?

  - by Frank Schwieterman

  I was running an amd64 build of Ubuntu on a VM on a Windows host which was also amd64. Later I found I could not run the same amd64 iso on my laptop, which is intel without hyper-V. I was confused I thought chipset mattered, but maybe it does not. When buying a PC or Apple, is there anything to check about the chipset to make sure it can run different types of VMs? In my case, I was trying to run ubuntu on a Thinkpad T520. Per answer below, I did need to enable some bios settings. I'm still having some issues. Running ubuntu on virtual box, when I try to use ubuntu-12.10-server-amd64.iso for the CD/DVD device to start a new VM, virtualbox complains "Failed to open the CD/DVD image . Could not get the storage format of the medium (VERR_NOT_SUPPORTED). When I try to use ubuntu-12.10-server-i386.iso the ISO is accepted, but then the VM complains "FATAL: No bootable medium found! System halted." I had been using an amd64 iso on my home PC which is amd64 and it works fine, which is why I suspected CPU mismatch was the problem at first. But it seems like I'm having issues, and maybe this superuser thread can be used to verify the cpu is irrelevant in this case.

• SATA Blu-Ray drive not detected via USB adapter

  - by LTR

  I'm using an SATA blu-ray drive (Lite-On IHOS104), connected via a USB adapter to my Windows 7 (32-bit) notebook. The first time I plugged the adapter in, it worked perfectly. The drive appeared in Explorer, and my player software was able to play an encrypted Blu-Ray disc just fine. After the first reboot, it never worked again. Now it shows up as "removable media" with a size of 0 bytes, irregardless of whether a disk is inserted or not. The drive does not show up under the green "eject USB device" icon in the taskbar. The adapter is powered using a separate power adapter. I have tried: disconnecting all other USB devices testing with a DVD instead of a Blu-Ray disc letting Windows search for updated drivers for the drive - there are none using the same drive and adapter on another Win7 (but x64) computer. They work perfectly. using other USB ports on the same notebook - tried them all. using a different SATA/USB-adapter What else can I do to diagnose this problem?

• Is there a way of using ctrl-r after typing part of command in bash?

  - by skeept

  In bash the ctrl-r command is very useful, I type ctrl-r whatever and it searchs my history for commands containing the word whatever. But if I type whatever and realize that I would like search that word and hit ctrl-r nothing happens. Is there a way hitting a key and having it behaving as if I had typed ctrl-r whatever instead of whatever ctrl-r? I have the following in my .inputrc "\C-p": history-search-backward but this only works if the beginning of the line is the same.

• OSX: Howto start VirtualBox VM on startup?

  - by snies

  The Question How do i start this Wiki VM at the startup of the OSX Server? I am running OSX Server 10.6.8 and VirtualBox 4.1.8 r75467 and a Debian Linux VM (called "wiki"). . What I tried so far Following this article: http://mikkel.hoegh.org/blog/2010/12/23/run-virtualbox-boot-mac-os-x/, i have wrote this plist and placed it in /Library/LaunchDaemons/bar.foo.WikiVirtualBox.plist: <plist version="1.0"> <dict> <key>Label</key> <string>bar.foo.WikiVirtualBox</string> <key>ProgramArguments</key> <array> <string>/usr/bin/VBoxHeadless</string> <string>-s</string> <string>wiki</string> </array> <key>RunAtLoad</key> <true></true> <key>UserName</key> <string>root</string> <key>WorkingDirectory</key> <string>/var/root</string> <key>StandardErrorPath</key> <string>/var/log/bar.foo.WikiVirtualBox.stderr.log</string> <key>StandardOutPath</key> <string>/var/log/bar.foo.WikiVirtualBox.stdout.log</string> </dict> </plist> and told launchd to start it: sudo launchctl load -w /Library/LaunchDaemons/bar.foo.WikiVirtualBox.plist . The Logfile But the VM doesn't start. A Look at tail -f /var/log/system.log shows: sudo[1909]: administrator : TTY=ttys000 ; PWD=/Users/administrator ; USER=root ; COMMAND=/bin/launchctl load -w /Library/LaunchDaemons/bar.foo.WikiVirtualBox.plist VBoxSVC[1914]: 3891612: (connectAndCheck) Untrusted apps are not allowed to connect to or launch Window Server before login.

• Verification as QA - makes sense?

  - by user970696

  Preparing my thesis, I found another interesting discrepancy. While some books say verification it terms of static analysis of work products is quality control (looking for defects), other say it is actually quality assurance because the process of checking is decreasing the probability of real defects when these deliverables will be used for product manufacture. I hesitate as both seems to be correct: it is a way of checking for defects (deviation from requirements, design flaws etc.) so it looks like quality control, but also it is a process which does not have to be done and if done, can yield better quality.

• Compiled code spreadsheet-like cell management? (auto-updating)

  - by proGrammar

  Okay so I am fully aware how spreadsheets manage cells, they build dependency graphs where when one cell changes it tells all the other cells that are dependent on it that it changed. So they can from there update. How they update I think involves either re-evaluating the formulas stored as strings, or re-evaluating the abstract syntax tree which I think is stored differently and might be faster. Something like that. What I'm looking to do is manage a few variables in my code so I don't have to update them in the correct way, which would be a nightmare. But I also want it much faster than spreadsheets. And since I'm not looking for any functionality as great as are in these spreadsheets, I just figured from that thought point that there has to be a way to have a very fast implementation of this functionality. Especially since I don't have to modify cells after compiling unless that would be an option. I'm very new to programming so I have no idea. One example might be to have a code-generator that generates code that does this for me. But I have no clue what the generated code would look like. Specifically, how exactly would variables inform others that they need to update, and what do those variables do to update? I'm looking for any kind of ideas. Programming is not my job but nonetheless I was hoping to have some kind of system like this that would greatly help me with some stuff. Of course I have been programming plenty lately so I can still program. I just don't have the full scope on things. I'm looking for any kind of ideas, thank you very much in advance! Also, please help me with the tags. I know C# and Java mainly and I'm hoping to implement this in either of those languages and I'm hoping this can stay in those tags. Forcing this into some kind of spreadsheet tag wouldn't be accurate.

• How to approach iOS web clip app "download"?

  - by Ryan

  We have our main site at: http://mysite.com which we don't want to alter. Then we have our web clip app at: http://mysite.com/app/ If someone visits the app URL in normal Safari then the Safari UI will still display. But if the user adds the app URL to their home screen, and then they tap that icon they will launch the app URL without the Safari UI as intended. My question is how do you go about getting the user to use the web clip app from their home screen when they start from mysite.com? What I'm thinking is that we have a link on mysite.com that points to mysite.com/app/. Then when they click that /app/ link they'll go to the app but it won't be in "app mode". Can I detect that it's not in app mode and display a message like "add this page to your home screen to use the app"? And then when they do visit in app mode obviously just let the app run.

• Why fgetc too slow?

  - by user14284

  I've written a program that reads an whole file via fgetc: while ((c = fgetc(f)) != EOF) { ... } But the program is too slow. When I changed fgetc to fread, static unsigned char buf[4096]; while ((n = fread(buf, 1, sizeof(buf), f)) > 0) { ... } the program works about 10 times faster. Why? As I know, fgetc is a buffered function, so it should work as fast as the second version with explicit buffer, isn't it?

• Places to share my new blog entry? [closed]

  - by TomasAlabes

  I started yesterday a tech blog called devhike and as my first entry I explained a palette behaviour made with RaphaelJS. I wanted to share the entry the tech people around the world, to see if they like it, find it useful, etc. I submitted the link to my post in dzone.com and hackernews which are the places from where I like to read tech articles, but I feel there should be other places where I could post my blog or entry too. If not, I feel my blog will never be read. Do you know any places or ways to be read?

  - by REACHUS

  Problem: Fill all the cells using distinct numbers from <1,25 set, so that sum of two adjacent cells is a square number. (source: http://grymat.im.pwr.wroc.pl/etap1/zad1etp1213.pdf; numbers 20 and 13 have been given) I've already solved this problem analytically and now I would like to approach it using an algorithm. I would like to know how should I approach these kind of problems in general (not a solution, just a point for me to start).

• Statistical Software Quality Control References

  - by Xodarap

  I'm looking for references about hypothesis testing in software management. For example, we might wonder whether "crunch time" leads to an increase in defect rate - this is a surprisingly difficult thing to do. There are many questions on how to measure quality - this isn't what I'm asking. And there are books like Kan which discuss various quality metrics and their utilities. I'm not asking this either. I want to know how one applies these metrics to make decisions. E.g. suppose we decide to go with critical errors / KLOC. One of the problems we'll have to deal with with that this is not a normally distributed data set (almost all patches have zero critical errors). And further, it's not clear that we really want to examine the difference in means. So what should our alternative hypothesis be? (Note: Based on previous questions, my guess is that I'll get a lot of answers telling me that this is a bad idea. That's fine, but I'd request that it's based on published data, instead of your own experience.)

• Validation and Verification explanation (Boehm) - I cannot understand its point

  - by user970696

  Hopefully my last thread about V&V as I found the B.Boehm is text which I just do not understand well (likely my technical English is not that good). http://csse.usc.edu/csse/TECHRPTS/1979/usccse79-501/usccse79-501.pdf Basically he says that verification is about checking that products derived from requirements baseline must correspond to it and that deviation leads only to changes in these derived products (design, code). But he says it begins with design and ends with acceptance tests (you can check the V model inside). The thing is, I have accepted ISO12207 in terms of all testing is validation, yet it does not make any sense here. In order to be sure the product complies with requirements (acceptance test) I need to test it. Also it says that validation problems means that requirements are bad and needs to be changed - which does not happen with testing that testers do, who just checks correspondence with requirements.

• Can I implement the readers and writers algorithm in OpenMP by replacing counting semaphores with another feature?

  - by DeveloperDon

  After reading about OpenMP and not finding functions to support semaphores, I did an internet search for OpenMP and the readers and writers problem, but found no suitable matches. Is there a general method for replacing counting semaphores in OpenMP with something that it supports? Or is there just a gap in the environment where it does not permit things that are asymmetrical like the third readers and writers problem shown on the following page? http://en.wikipedia.org/wiki/Readers-writers_problem#The_third_readers-writers_problem
