• How to start Ubuntu with no working video card?

  - by ViliusK

  I have a laptop with broken video card. It has two operating systems installed - Windows 7 and Ubuntu 10.10 Desktop Edition. It has GRUB to manage which operating system to boot up. Windows is default OS. And Windows fails to boot up without video card. I'm checking with ping to the ports which are shown as used by DHCP in my router. Normal boot of Ubuntu also fails and it restarts after a while. But when I choose (blindly, but checking HDD indicator and by counting button presses when GRUB menu appears) to boot second option of Ubuntu (rescue mode) it starts and I can ping it. But when I try to connect to it through SSH, I'm getting "connection refused" error from putty. I've took out HDD from my laptop already and inserted it to WD Passport case so now I can connect it to other computer to edit configuration files. How can I check if SSH server is working? How to enable it in rescue mode? Or better, how to disable video card to be required while booting Ubuntu in normal mode?

• Amazon Careers website - are resumes processed in plain text format only?

  - by sapphiremirage

  The submission site has the following options: "Please upload your resume (Word Document, max size: 512 KB) OR Please copy and paste the text version of your file here", with a text box below the latter option. I went ahead and uploaded my shiny LaTeX resume (as a PDF), despite the fact that they seem to want a Word Document, and there didn't seem to be any issues. However, when I went back to edit my profile, there was no evidence that my PDF had been uploaded, other than a text version of my resume, awfully formatted and clearly stripped from the PDF, sitting in the text box below "Please copy and paste the text version of your file here". Exasperated, I did a quick and dirty copy of the text from my resume into a Word doc and uploaded that. Same result: no evidence of a file uploaded, just a stripped text version in the textbox. What I'm wondering now is, are they only going to look at the text version of my resume? If that's the case then I'm obviously going to edit it so that it looks halfway decent and doesn't contain such atrocities from the conversion as "Other Skills: LTEX". I can pretty little text files without too much effort, so this isn't that big of deal. However, my LaTeX resume is going to look better than anything I can do in plain text, so if the site is actually keeping a copy of that, then I certainly don't want to override it. Has anyone here either gone through the Amazon hiring process or interviewed candidates and know how this works? (i.e. When on site with Amazon, did the interviewers have diversely formatted resumes, or did they all look suspiciously similar)

• How do I configure namecheap for "arbitrarily-nested" wildcard subdomains?

  - by rabidsnail

  I'm trying to set up something like nyud.net, where any arbitrary chain of subdomains resolves to the same CNAME record (which in my case points to an amazon elastic load balancer). Ex: www.gogle.com.nyud.net:8080 points to one of their cache servers, which looks at the HOST header and returns www.google.com. I'm using namecheap as my dns host. Adding a CNAME record for *.mydomain.com doesn't seem to do anything (nslookup gives NXDOMAIN for all subdomains). What do I have to do to set this up? Do I have to use something fancier than namecheap (like route53)?

• How to kill an openvz container?

  - by johannes

  An openvz container can be stopped with vzctl stop <id> , but this needs the cooperation from the init inside the container. In case a container is compromised a way is needed to stop the container withouts its cooperation. Something like a vzctl kill <id> is needed which kills all processes inside the container and puts it into the stopped state. Such a kill command is not listed in the manpage. How can an openvz container be killed/stopped without needing it's cooperation?

• No display but video card fans spins

  - by Marc

  Since I moved my computer there's no display when I plug my screen in the video card but works fine in the mother board. I tried reseting the cmos, but I still have the same problem. The fans are spining and there's a light from the card. I tried the DVI ports and the HDMI Here's my build. I have it for 2 months and everything was working fine. Do you think it's the video card?

• Is there an image viewer which *won't* show every file in the current folder?

  - by hawbsl

  Looking for a Windows image viewer which can be started from the command line but which allows me to specify/restrict which files I want it to page through. As parameters. The good 'ol Windows Picture Viewer would be fine except that it'll show/cycle through all the pictures in the current folder. In my case I want to say something like: someimgvwr.exe "cat.jpg" "cow.jpg" "cub.jpg" so that only those three files will be displayed and not "pig.jpg" which might also happen to be there in the same folder. Actually, if it allowed something like this: someimgvwr.exe "c*.jpg" that would be even more perfect. Do any of the many image viewers that are out there allow such a thing?

• Solving the puzzle in javascript [on hold]

  - by Gandalf StormCrow

  I've recently try to brush up my javascript skills, so I have a friend who gives me puzzles from time to time to solve. Yesterday I got this : function testFun() { f = {}; for( var i=0 ; i<3 : i++ ) { f[i] = function() { alert("sum='+i+f.length); } } return f; } Expected Results: testFun()[0]() should alert “sum=0” testFun()[1]() should alert “sum=2” testFun()[2]() should alert “sum=4” I did this which does like requested above: function testFun() { var i, f = {}; for (i = 0; i < 3; i++) { f[i] = (function(number) { return function() { alert("sum=" + (number * 2)); } }(i)); } return f; } Today I got new puzzle : Name everything wrong with this javascript code, then tell how you would re-write it. function testFun(fInput) { f = fInput || {}; // append three functions for( var i=0 ; i<3 : i++ ) { f[i] = function() { alert("sum='+i+f.length); } } return f; } // Sample Expected Results (do not change) myvar = testFun(); myvar[0](); // should alert “sum=0” myvar[1](); // should alert “sum=2” testFun(['a'])[2](); // should alert “sum=5”`enter code here How do I accomplish the third case testFun(['a'])[2]()? Also could my answer from yesterday be written better and what can be improved if so?

• Replace files with symlink

  - by soandos

  This question is intended to be the inverse of Replace Symbolic Links with Files, but for windows. I have started running out of space on my SSD drive, and I found that about 12% of used space is in my installer folder (holds the .msi files for all the programs that I have installed) I am looking for two things: A way to move this (or any) folder via symlink. Ideally, some powershell function that I could use to just designate a folder, a destination, and the symlink would be created in the original (pointing to the destination) In this particular case, a registry change that would allow the location to be move would also be helpful, but I would still prefer solution 1. How can this be done?

• How to reference individual cells in Excel to variable data from records in an external SQL table

  - by user273476

  I have a SQL table containing date oriented financial data eg. multiple daily records with fields for Date, Account code and Value. I want to set up dynamic links (formulas) from cells in an Excel speadsheet to this data so when the spreadsheet is loaded the data is fetched from all the relevant records. The spreadsheet has the Account codes on the x axis and Dates on the y. Each day the SQL table has new data in it for the new day and I want the spreadsheet to reference this new data for the column for the new day. Any ideas? I have seen how you can generally bring in data from a SQL table (in our case using ODBC as it is not MS SQL) but the data is not simply bringing in multiple records as you would a CVS file but specific records in the SQL table referencing to specific cells and columns in the spreadsheet.

• How do I configure the Google Chrome / Chromium address bar to perform a search instead of trying to access a file on the local file system?

  - by Daniel Kauffman

  How do I configure the Google Chrome / Chromium address bar to perform a search instead of trying to access a file on the local file system? I would like to be able to enter a file name in the address bar and to see Google search results for that file name similar to what I would see if I searched for the file name using something like https://www.google.com/#q=/path/to/interesting/file I am able to disable the file scheme using either of the following policy settings: "DisabledSchemes": ["file"], Which has been deprecated in favor of: "URLBlacklist": ["file://"], But in either case Google Chrome / Chromium continues to auto-detect that a file name was entered, automatically prepends the file scheme to the file name, and then reports that the webpage is blocked.

• Should I sell video tutorials on my own or via publishers like lynda.com? [closed]

  - by Derfder

  I am asking this because I am deciding between two models right now. One way is to create video tutorials on my own (make some short free videos and long pay per download/stream videos) or sell them to lynda.com or tutsplus. The 2nd way is easier, because they will do all the boring business stuff, will host the files to download etc. In that case, everything I need is a good microphone and obey their guidelines. On the other side if I do it on my own, I have to do all the unwanted business stuff, pay the server and other stuff. This is quite a big downside, however, I will have all the videos under my control in the future. I know that lynda.com has bigger attention and marketing that I am capable, but if you take e.g. phpvideotutrials.com (r.i.p ;), I think Leigh was very successful with relatively small budget. The interesting question will be the cost or how much will they pay me. Would it be less than if I sell it myself+monthly server hosting+other expenses? Any advice from people who actively sell their videos to some companies or do it on they own is highly appreciated.

• Best idea dataserver serving small pictures 40 ko

  - by Nicolas Manzini

  I'm designing the server structure for my application in case things go well. I have one server DB connected to multiple server who process connections. All those with lots of RAM and fast processors. (still looking for a way to use the multithread because now it's dumb apache php... so loooots of ram needed). Upon an answer from those servers, the client can then connect to another server to retrieve pictures using the address he previously got from the db. Is it a good idea to have one database server with let's say nginx and ssd disk having to send all pictures to everybody? or should I have multiple server accessing to a shared ssd disk drive or multiple disk updating each other? Also should I put a lot of RAM on the database server? because probably there wont be a picture more popular than another.

• Trying to get a new user up on pfSense IPSec VPN; Config file import failed, now getting gateway err

  - by Chris

  Caveat: I am not a sysadmin, so please forgive the n00bness of the query. We have a new user and I'm trying to get them up on VPN. We use pfsense as an IPSEC endpoint. This person is using Shrewsoft for the client. I had created an entry in pfsense for them and then edited a previous user's config file. Shrewsoft didn't import the config file very well and I had to hand edit the information. Now we are getting gateway errors. One thing I've noticed is that there is a different between the values of the preshared key stored on the firewall and the psk stored in the config file. I assume it has something to do with a hash, but I've no idea if that's the case and whether that might be what's causing the problem. Any suggestions greatly appreciated! Tangentially, is there some software used to generate these config files?

• MySQL Unions/Subselects not utilizing keys from associated tables

  - by Brett

  I've noticed by doing EXPLAINs that when a MySQL union between two tables is used, mysql creates a temporary table, but the temp table does not use keys, so queries are slowed considerably. Here is an example: SELECT * FROM ( SELECT `part_number`, `part_manufacturer_clean`, `part_number_clean`, `part_heci`, `part_manufacturer`, `part_description` FROM `new_products` AS `a` UNION SELECT `part` as `part_number`, `manulower` as `part_manufacturer_clean`, `partdeluxe` as `part_number_clean`, `heci` as `part_heci`, `manu` as `part_manufacturer`, `description` as `part_description` FROM `warehouse` AS `b` ) AS `c` WHERE `part_manufacturer_clean` = 'adc' EXPLAIN yields this: id select_type table type possible_keys key key_len ref rows Extra 1 PRIMARY <derived2> ALL (NULL) (NULL) (NULL) (NULL) 17206 Using where 2 DERIVED a ALL (NULL) (NULL) (NULL) (NULL) 17743 3 UNION b ALL (NULL) (NULL) (NULL) (NULL) 5757 (NULL) UNION RESULT <union2,3> ALL (NULL) (NULL) (NULL) (NULL) (NULL) In this case, part_manufacturer_clean and manulower are keys in both tables. When I don't use the subselects and union, and just use one table, everything works fine. I'm not sure if the issue is with the union or with the subselects. Is there any way to union two tables and still use keys/indexes for performance?

• Windows 7 is blocking ports

  - by Caleb1994

  I am trying to open port 80 and 3690 for HTTP and svnserve respectively. I have Windows Firewall off, and have tried temporarily disabling Mcafee VirusScan Enterprise, to no avail. According to http://www.yougetsignal.com/tools/open-ports/, both ports 80 and 3690 are still blocked. I can't think of what would be blocking them if Windows Firewall and my antivirus are disabled. Here is the output of netsh firewall show state Firewall status: ------------------------------------------------------------------- Profile = Standard Operational mode = Disable Exception mode = Enable Multicast/broadcast response mode = Enable Notification mode = Enable Group policy version = Windows Firewall Remote admin mode = Disable Ports currently open on all network interfaces: Port Protocol Version Program ------------------------------------------------------------------- 3690 TCP Any (null) 22 TCP Any (null) 80 TCP Any (null) 1900 UDP Any (null) 2869 TCP Any (null) Any help? I'm not sure what each item on the list of enabled/disabled items is, but "Operational Mode" is disabled, so I assume that one refers to me disabling Windows Firewall. I know that since Windows Firewall is off, this output might not be useful, but I figured I'd include it just in case, haha.

• How to have an Arduino wait until it receives data over serial?

  - by SonicDH

  So I've wired up a little robot with a sound shield and some sensors. I'm trying to write a sketch that will let check the sensors. What I'd like for it to do is print out a little menu over serial, wait until the user sends a selection, jump to the function that matches their selection, then (once the function is done) jump back and print the menu again. Here's what I've written, but I'm not a that good of a coder, so it doesn't work. Where am I going wrong? #include <Servo.h> Servo steering; Servo throttle; int pos = 0; int val = 0; void setup(){   Serial.begin(9600);   throttle.write(90);   steering.write(90);   pinMode(A0, INPUT);   pinMode(7, INPUT);   char ch = 0; } void loop(){   Serial.println("Menu");   Serial.println("--------------------");   Serial.println("1. Motion Readout");   Serial.println("2. Distance Readout");   Serial.println("3. SD Directory Listing");   Serial.println("4. Sound Test");   Serial.println("5. Car Test");   Serial.println("--------------------");   Serial.println("Type the number and press enter");   while(char ch = 0){   ch = Serial.read();}   char ch;   switch(ch)   {     case '1':     motion();   }    ch = 0; } //menu over, lets get to work. void motion(){   Serial.println("Haha, it works!"); } I'm pretty sure a While loop is the right thing to do, but I'm probably implementing it wrong. Can anyone shed some light on this?

• High frequency, kernel bypass vs tuning kernels?

  - by Keith

  I often hear tales about High Frequency shops using network cards which do kernel bypass. However, I also often hear about them using operating systems where they "tune" the kernel. If they are bypassing the kernel, do they need to tune the kernel? Is it a case of they do both because whilst the network packets will bypass the kernel due to the card, there is still all the other stuff going on which tuning the kernel would help? So in other words, they use both approaches, one is just to speed up network activity and the other makes the OS generally more responsive/faster? I ask because a friend of mine who works within this industry once said they don't really bother with kernel tuning anymore-because they use kernel bypass network cards? This didn't make too much sense as I thought you would always want a faster kernel for all the CPU-offloaded calculations.

• Windows 8 Color Settings (Window Title)

  - by xixixao

  In Windows 7, the window title's color (by default black, to see the title in the title bar fire up Windows Media Player for example) is stored in [HKEY_CURRENT_USER\Control Panel\Desktop\Colors] TitleText value. This is not the case in Windows 8, since this value is only used when using high contrast theme. It looks like noone has come up with a way to change this color yet, so my question is, where to look? What tools can I use to see dependencies, what could be the way to find this value (I rightfully hope it's not a constant in code).

• dpkg -S not showing all files in package

  - by dimadima

  I've been using dpkg -S <package_name> to list the contents of a package. Sometimes I pipe to grep bin to quickly scan for executables. I just ran into a case where this didn't work out for me: $ which virtualenv $ sudo apt-get install python-virtualenv Reading package lists... Done ... Setting up python-virtualenv (1.7.1.2-1) ... $ which virtualenv /usr/bin/virtualenv $ dpkg -S /usr/bin/virtualenv python-virtualenv: /usr/bin/virtualenv $ dpkg -S python-virtualenv | grep bin $ /usr/bin/virtualenv seems to be provided by python-virtualenv, but isn't listed in the package contents provided by dpkg -S. All the while, passing /usr/bin/virtualenv to dpkg -S returns that the file comes from python-virtualenv. Can you all explain this?

• How to close buffer without closing the window?

  - by progo

  I usually open a few windows and keep some buffers open. Since my MO in buffer exploring is to use quick shortcuts to :bn and :bp, I want to close unneeded buffers from distracting my buffer surfing. But the pain is, issuing :bd and :bw results in closing the window as well, in case I have multiple ones open. How do I close (delete) a buffer and leave the windows intact? Solution inspired by @peth's answer :command! BW :bn|:bd# It is simple. Doesn't work well with only one buffer open (I get different behaviour depending on the way I open the files) but it isn't a big issue. :)

• Unity gizmos vs. referenced game objects

  - by DuckMaestro

  I'm designing a Unity script that I intend to be highly reusable and as easy as possible to setup within the editor. To this end, a number of properties of this script really need some kind of visual representation on screen. It is an unresolved question to me whether the design of the script should require references to placeholder game objects, OR just Vector3's and float's that have associated gizmos drawn for them. Normally a gizmo would be a natural choice, except that Unity gizmos are not directly manipulable (as far as I can tell). Because of this shortcoming I'm having to consider whether depending on references to placeholder game objects is a more designer-friendly approach ultimately, in spite of the extra setup required, and that it might be counter-intuitive when the placeholder game objects disappear at run-time (which my script would do). Is there a community standard or preference here in this case? Can a Unity-experienced game programmer / designer speak to which approach they feel is more intuitive or more convenient to setup, when using a 3rd party script? Or is this just splitting hairs as long as I ship an example prefab with my script?

• "Misaligned partition" - Should I do repartition (how?)

  - by RndmUbuntuAmateur

  Tried to install Ubuntu 12.04 from USB-stick alongside the existing Win7 OS 64bit, and now I'm not sure if install was completely successful: Disk Utility tool claims that the Extended partition (which contains Ubuntu partition and Swap) is "misaligned" and recommends repartition. What should I do, and if should I do this repartition, how to do it (especially if I would like not to lose the data on Win7 partition)? Background info: A considerably new Thinkpad laptop (UEFI BIOS, if that matters). Before install there were already a "SYSTEM_DRV" partition, the main Windows partition and a Lenovo recovery partition (all NTFS). Now the table looks like this: SYSTEM_DRV (sda1), Windows (sda2), Extended (sda4) (which contains Linux (sda5; ext4) and Swap (sda6)) and Recovery (sda3). Disk Utility Tool gives a message as follows when I select Ext: "The partition is misaligned by 1024 bytes. This may result in very poor performance. Repartitioning is suggested." There were couple of problems during the install, which I describe below, in the case they happen to be relevant. Installer claimed that it recognized existing OS'es fine, so I checked the corresponding option during the install. Next, when it asked me how to allocate the disk space, the first weird thing happened: the installer give me a graphical "slide" allocate disk space for pre-existing Win7 OS and new Ubuntu... but it did not inform me which partition would be for Ubuntu and which for Windows. ..well, I decided to go with the setting installer proposed. (not sure if this is relevant, but I guess I'd better mention it anyway - the previous partition tools have been more self-explanatory...) After the install (which reported no errors), GRUB/Ubuntu refused to boot. Luckily this problem was quite straightforwardly resolved with live-Ubuntu-USB and Boot-Repair ("Recommended repair" worked just fine). After all this hassle I decided to check the partition table "just to be sure"- and the disk utility gives the warning message I described.

• Laptop white screen on power-up. Still displays via HDMI output

  - by Inno

  my wife's laptop recently started displaying a white screen. It doesn't show post or anything, just a white screen when it's powered on. However, it works normally with HDMI output to our television. I took it apart and fiddled with both ends of the display cable, but I either didn't fiddle correctly or that's just not the problem. I also noticed that the screen won't turn off anymore when the laptop is closed. Is there a name for the mechanism that controls this function, so I can try and locate it? My guesses are that the problem lies with the screen itself or the display cable, but I'm curious if there's anything else I might be overlooking. Also of note is that the left hinge is partially broken. The corner of the plastic computer case broke off, so the hinge is exposed and doesn't stay in place. I've tried holding it in place, wiggling it around, tapping various parts of the computer, but the white screen remains.
