• How to focus on one topic? [closed]

  - by Brian

  I have a huge problem while reading computer books. Every couple pages I'll end up googling something I want to learn more about, but then I'll find something on that page that I'll want to learn more about and google that (sometimes programming related, sometime hardware related). Normally after wasting around 3 hours going into different subjects I'll return to the original text only to repeat the process a few pages later. Any advice for sticking to one subject and learning that in-depth? I have tons of programming books I've read half-way through since I'll become interested in other languages/topics (not that I'm not interested in the books I've started). Also, what would be worth focusing on in depth? I've gone into Python in the most depth but for classes I'm learning Java and assembly (ARM and Motorola 68000). Also, I've taken a class on C++. Lately I've been spending most of my time learning about Linux instead of programming though. I'm not sure what would be worth focusing on the most to get a job. In other words, how can you focus on one topic and not let curiosity about everything else get in the way? Thanks in advance, Brian

• What has changed to make it possible to develop USB3.0

  - by RoboShop

  Like I know the transfer speeds are vastly different. But I don't understand is why they are faster. And why couldn't they have implemented USB 3.0 when they released 1.0? Like what technical breakthrough was required to get transfer speeds that fast? Was it cost? capacities of computer? like they couldn't read the data fast enough? Although USB is still well below hard drive transfer speeds engineering breakthrough? They found some new material which could transfer at a faster rate? Was this in the cable itself? In the hardware?

• Uninstalled Ubuntu, no GRLDR?

  - by user32965

  So I'm a big fat idiot. I installed Ubuntu 11.04 on my school's laptop, and here's come the time that I have to turn it back in. I wrote GRUB to the Master Boot Record, thinking it wasn't going to be permanent. So, fast forward to yesterday. I decided to hell with this, and popped in my Windows 7 CD, deleted the whole partition, formatted to NTFS, and installed Windows 7 on it. I'm surfing the web and my computer overheats [totally typical] I boot up, and get this: Try (hd0,0): FAT32: No GRLDR Try (hd0,1): invalid or null Try (hd0,2): invalid or null Try (hd0,3): invalid or null Try (hd1,0): NTFS5: No grldr Try (hd1,1): invalid or null Try (hd1,2): invalid or null Try (hd1,3): invalid or null Cannot find GRLDR. Press space bar to hold the screen, any other key to boot previous MBR... Timeout: 5 The timeout part just counts down to 0 from 5. I need to turn in this thing before tomorrow, please please please can someone help me out?

• openssl creates invalid signature if run by a different user

  - by divB

  Very strange problem here: openssl successfully creates signatures but only those created as root are valid whereas created by another user (www-data) are invalid! All files are readable and there are not error messages: # echo -ne Test | openssl dgst -ecdsa-with-SHA1 -sign activation.key > /tmp/asRoot.der # su www-data $ echo -ne Test | openssl dgst -ecdsa-with-SHA1 -sign activation.key > /tmp/asWww-data.der $ uname -a Linux linux 2.6.32-5-openvz-amd64 #1 SMP Mon Feb 25 01:16:25 UTC 2013 i686 GNU/Linux $ cat /etc/debian_version 6.0.7 Both files (asRoot.der and asWww-data.der) are transfered to a different computer for verification with the public key: $ echo -ne Test | openssl dgst -verify activation.pub -keyform DER -signature asRoot.der Verified OK $ echo -ne Test | openssl dgst -verify activation.pub -keyform DER -signature asWww-data.der Verification Failure That can't be true!

• Why can't I reconnect to my Philips SHB9000 bluetooth headset?

  - by Thomas Eyde

  When I connected my Philips SHB9000 bluetooth to my Windows 7 (64 bit) for the very first time, it worked well. I had to manually change the default playback device, but otherwise it worked. Then, when I start up my computer from standby, it's nearly random when I can reconnect or not. My last option is to remove the bluetooth device and reconnect it. But now, even that doesn't work. The sad thing is, this used to work better on Windows 7 beta. Windows Update has a new driver which fails to install. Searching for this driver yields nothing. I thought all vendors had an official site for their drivers? Well, Philips seems to have none. If there is no answer to this problem, my advice is to NOT buy this headset. It's good looking, the sound is nice, but what need do we have from that if we can't use the bloody device?

• Extremely simple online multiplayer game

  - by Postscripter

  I am considering creating a simple multiplayer game, which focuses on physics and can accommodate up to 30 players per session. Very simple graphics, but smart physics (pushing, weight and gravity, balance) is required. After some research I found a good java script (framework ??) called box2d.js I found the demo to be excellent. this is is kind of physics am looking for in my game. Now, what other frameworks will I need? Node.js?? Prototype.js?? (btw, I found the latest versoin of protoype.js to be released in 2010...?? is this still supported? Should I avoid using it?) What bout HTML 5 and Canvas? would I need them? websockets? Am a beginner in web programming + game programming world. but I will learn fast, am computer science graduate. (but no much web expeience but know essentionals javascript, html, css..). I just need a guiding path to build my game. Thanks

• Unable to install Android for Windows 7 because JDK is not found

  - by user1294663

  I have JDK SE7u4 installed in windows 7. I tried to install Android on Windows 7 using the installer_r18-windows.exe but no avail. The setup window showed the message saying that the Java SE JDK not found and ERROR: Failed to find Java version for C:\Windows\System32\java.exe The system cannot found the file specified. If you believe you have a JDK installed and it was not properly recognized, simply set an environment variable JAVA_HOME to point to it I right clicked on Computer Properties Advanced System Settings Environment variables. I created a NEW system variable called JAVA_HOME and set the value as C:\Program Files\Java\jdk1.7.0_04\bin or C:\Windows\System32\java.exe. I ran the installer again — the same error message still appeared.

• Is there a way to have a working search bar in Explorer with Windows Search Service disabled?

  - by Desmond Hume

  I had to disable Windows Search Service (turn it off in Windows Features) for the reason that it was constantly using the hard drive in an excessive way (maybe because I've got very large quantities of files on my PC), noticeably slowing down my computer, and the Windows.edb database file grew way too large, about 2.5 GB in size. But the side-effect of it is that now the search bar is gone from any Explorer window and I miss this useful feature. So my question is, is there a way to stop Windows Search Service torturing my hard drive and still being able to search for files and folders directly from Explorer, perhaps using some third-party software?

• What can I do to utilize all my hard disk space?

  - by Twatcher

  I had windows XP running on my computer. Then I installed Ubuntu from under windows. Then I decided I wanted to have only Ubuntu also because I got a system message that I am out of disk space. I loaded up my system from a live Ubuntu DVD and deleted the partition with windows on it and also the other partition that had my data on it. I expanded the partition which I thought to be the system partition (since there was no other partition left It had ext format. After that Ubuntu was working fine and I thought I have enough disk space, since my harddrive is an 80 GB ATA Maxtor. I left a small partition as backup. But after downloading a small amount of files I got the message again, that I am running out of disk space. I don't now. How can UI make my disk space bigger? I am not used to Ubuntu's file system, and I don't have the overview on how I can actually see how much space there is left for me to use. I have basically now 1 partition with the system on it and one small backup (as far as I understand). My system is (from system utility) Ubuntu 12.04 LS 3,9 GB Intel Core 2 2,4 Ghz 80 GB ATA Maxtor Here are the results for sudo fdisk -l Disk /dev/sda: 80.0 GB, 79998918144 bytes<br> 255 heads, 63 sectors/track, 9725 cylinders, total 156247887 sectors<br> Units = sectors of 1 * 512 = 512 bytes<br> Sector size (logical/physical): 512 bytes / 512 bytes<br> I/O size (minimum/optimal): 512 bytes / 512 bytes<br> Disk identifier: 0x41ab2316<br> Device Boot Start End Blocks Id System<br> /dev/sda1 * 63 123750399 61875168+ 7 HPFS/NTFS/exFAT<br> /dev/sda2 123750400 156246015 16247808 7 HPFS/NTFS/exFAT<br>

• Why did the web win the space of remote applications and X not?

  - by Martin Josefsson

  The X Window System is 25 years old, it had it's birthday yesterday (on the 15'th). As you probably are aware of, one of it's most important features is the separation of the server side and the client side in a way that neither Microsoft's, Apples or Wayland's windowing systems have. Back in the days (sorry for the ambiguous phrasing) many believed X would dominate over other ways to make windows because of this separation of server and client, allowing the application to be ran on a server somewhere else while the user clicks and types on her own computer at home. This use obviously still exists, but is marginalized at best. When we write and use programs that run on a server we almost always use the web with it's html/css/js. Why did the web win, and X not? The technologies used for the web (said html/css/js) are a mess. Combined with all the back-end-frameworks (Rails, Django and all) it really is a jungle to navigate thru. Still the web thrives with creativity and progress, while remote X apps do not.

• Outlook 2007 attachments wont preview

  - by Slace

  When I get an email with an attachment in Outlook 2007 that I should be able to preview (ie - image, word doc, etc) I get the following error: This file cannot be previewed because of an error in the following previewer: Microsoft Outlook image previewer To open this file in its own program double-click it. (obviously the previewer changes name depending on the type) The computer is a clean install (it's only 5 days old) and I remember I was at one point able to preview within Outlook. I'd really like this feature to be back working, I've tried the usual exit Outlook, restart Windows, etc but to no avail.

• What would be a good topic for research on "edge of multiple processors / computers programming" topic?

  - by Kabumbus

  This is a subjective discussion so we can express our dreams and hopes here. A "topic" must be like a task with point to have as end result a software poduct. A "topic" must be mainly about "Software engineering", "Algorithm and data structure concepts" and perhaps "Design patterns". I mean let us try to look what is not already there? What can be developed in fiew month and give a breakthrue / start a new leap / show somethig not realized before in science of f multiple computers programming? What i see is already there: LAN / wire and other infrastractural programms for connecting on device level MPI/ Bit torrent/Jabber protocols / APIs / servers for messaging on top Boost and analogs on evry OS in most languages for multithreading there are lots of CUDA like on computer frameworks for fast calculating on computers GPUs What I personally do not see out there is a crossplatform framework for multiple processes interaction. Meaning one that would allow easy creation of multyple processes running in paralell inside one hoster app on one machine. In level not harder than needed for threads creation (so no seprate server apps - just one lib doing it all) Is there ny such lib and what can you propose for research topic?

• Single domain user can't install a specific shared network printer

  - by drpcken

  I have a file server serving up shared network printers. Never had any issues in the past. I have a specific domain user (just 1) that gets this error when trying to install a specific printer: You do not have sufficient access to your computer to connect to the selected printer This user can install all the other printers no problem. All my other domain users can install the printer with no problem. I've removed the driver from the local client and tried again but with the same problem. Even as an administrator I get this error. Is there something I'm missing?

• What is the minimum delay between two consecutive RS232 frames?

  - by Lord Loh.

  I have been working on creating a UART on an FPGA. I can successfully transmit and receive single characters typed on PuTTY. However, when I set my FPGA to constantly write a large sequences of "A", sometimes I end up with a sequences of "@" or some other characters until I reset the FPGA a few times. I believe the UART on the computer looses track of the difference between the start bit and a zero. The delay between the two "A" is ~ 30us (measured with a logic analyzer) and the baud rate is 115200 8N1. Is there a minimum delay that must be maintained between two consecutive RS232 frames?

• A software to lock regions of a screen to prevent any windows from overlapping

  - by cybervaldez

  I've just installed nexus dock (a similar application like rocketdock), after playing with the preferences i've come across a very curious option (under position & behavior) that says: Prevent maximized windows from overlapping the dock. With it enabled, any application I maximize(and i do mean any) won't overlap the dock, it's really great. So i'm thinking perhaps there's a software that does this kind of feature which is really ideal for keeping my workspace really organized. I really hate repositioning and resizing my windows everytime. Of course there's always the manual way of doing these but it's just too much of a bother when someone from the family uses the computer. Do you know any software that does this? even a software that can just save/remember window positions would also be nice too.

• Motherboard warning lights when plugging in a display port cord to graphics card?

  - by rllr

  Earlier today, my computer spontaneously shut itself off and refused to turn back on. I tested my PSU and it's operating fine. I unplugged everything and let it sit for a while and it started to make a high pitched coil whine/hiss. When I came back an hour later and plugged in only the power cord, it turned on without any issues. After some troubleshooting, I noticed my motherboard (Intel D975XBX2) has a red CPU led and VR led that come on whenever I plug my monitor into my graphics card via display port. DVI does not cause a similar issue. I was running three monitors off the card, so I need both DVI ports and the display port working. Is it likely my graphics card needs to be replaced, or should I be looking elsewhere to resolve this issue?

• View scheduled recordings remotely

  - by Scott

  I have one computer which is equipped with a TV tuner card. The Recorded TV folder is shared so that other computers on the network can watch recordings. Now that I am upgrading my computers to Windows 7, they have Media Center, which makes for a nicer viewing experience than a Windows Explorer folder view. I have set up Media Center on my laptop to considering the Recorded TV folder on the tuner-equipped PC as an extended library location, so now I can view all the recordings from within Media Center on the laptop. To make this experience even better, is there a way to view the list of scheduled recordings on the tuner-equipped PC from within Media Center on my laptop?

• Unable to get to main screen and safe mode doesn't help.

  - by Link

  It is my friends computer so I am not very familiar with it, I am unable to get it to start. I can get to the logon screen but after entering the password there is an error (something to do with Roxio) and only the background loads. No Start menu, Taskbar or icons. If I boot it in safe mode it gets stuck on a black screen and don't even get the command prompt. I am confident that If I could get to the menu to edit startup programs then I could fix the problem... any Ideas?

• Random shut down? Asus N53J Laptopi

  - by Mr.Y

  My Laptop is pretty new and today it random shut down on its own. I was surfing the net and the computer shut down on its own (Like losing power, without any warning). It was the 2nd time, the first time was 3 weeks ago. Btw it happens during cold days. I remember one time I was unable to turn on my laptop at all. So I'm pretty sure it's not related to heat issue... could it be the laptop is too "cold"? My room temperature is around 17=18 degree on average :P edit -I use Windows 7 Professional. -I run memtest86 once and it passed. -I run my laptop WITHOUT battery all the time.

• Prevent machine in a LAN from receiving a remote shutdown

  - by WebDevHobo

  I'm probably just overreacting, but I recently came across a LAN-scanner that showed me the option "remote shutdown", for all found computers on the scanned network. Now, how exactly does this work? If I send such a message, will the shutdown happen no matter what, or is it required to have the password/user-name of the user of that other computer. Mostly I'm wondering: can this be done to me and how do I prevent it? EDIT: what's more, I had the scanner check for shares. The result being this: Double clicking the links opens them in explorer, basically meaning my entire C and F drive(only 2 HD's I have) are completely exposed to anyone in my LAN. Or can I open these because it's my own machine?

• Ubuntu12.04 - launched applications, not staying in same desktop

  - by Anders Metnik

  My question is why a launched application, if it has loading time like netbeans, eclipse jdeveloper etc. If i go to desktop3 and launch an application and then go to desktop 2 while I wait, then when it has loaded the application will launch in desktop2. Is there anyway to change this? I find it highly annoying since i on startup would like to launch 3-4 big applications, leave my computer while loadingf, and then return. But i cant leave since i have to launch them sequential instead of simultaneous... Help please :-)
