• Learning node.js

  - by john smith

  I am not sure if this is the right place to ask but, I thought this was the most suitable. I recently graduated from university. Learned the full php stack; basically all the LAMP stuff, obviously without counting all the other subjects. Not even got my degree and this whole node.js booming out of nowhere. You can imagine how one can feel about this, the story is always the same: you never end learning, and studying. So I recently got my hands on node.js; reading books, tutorials, and everything imaginable on the internet. The problem is one and simple: this is nowhere near to having a teacher standing near you helping you understanding and solving your problems, especially when all you can do is post your doubts on a website and patiently wait for replies. It's not that it isn't good, it's just much slower than what I just expressed above. So, in short words: is there a place where one can find someone willing to teach you about such contents? This would obviously done via remote means, like skype and such. Can anyone here point me into the right direction? Or just downvote me for being in the wrong website? Thanks in advance.

• What music players (or related applications) are there that would allow displaying/editing embedded lyrics of music tracks?

  - by cipricus

  I use OSD Lyrics and CoverGloobus. They are good, they search and eventually download lyrics, when they can find them. The sources used by OSD Lyrics, for example, are rather limited (although I love the way it displays them. The latter accesses a reacher database, but the display is not adjustable as far as I know). Couldn't find a way to make these programs see lyrics from a file selected by me. What I want is to be able to add the lyrics myself, and even to embed them into the music file - and, of course, to display them from there. The last feature alone would be very valuable to me, as I have a large music database with lyrics already embedded, but I cannot see them with these programs: they are just looking for new lyrics on the Internet, although the lyrics are on my computer. In Windows I used Foobar2000 to find, display and embed lyrics (with the add-on lyricsgrabber) and when I needed to add the lyrics manually I used to embed them in MediaMonkey (this player allows finding them, but also editing and embedding - just by copy/paste). I am not able to run MediaMonkey in Wine. Foobar works, but with a lot of problems. And anyway, Wine is of last resort. I am looking for a Linux program that would be able to do something similar to what I have described above.

• On Windows 7, how can I make the Start Menu search feature include matches from within words, not just the start of the word?

  - by Gabriel

  I have a program installed called WinSCP. When I press the Windows key and type "SCP", I get "No items match your search." Is there a configuration option I can set somewhere, so that this item will be found? I'm not looking for a specific solution for this particular program, but something general, so that if there's a program named XYZ, I can find it via the Start Menu search by entering YZ. EDIT TO ADD: I'm looking for a "set-it and forget-it" type of configuration change, so that within-word searching happens always, automatically. I don't want to have to type a * before every query. Apparently this wasn't clear from what I wrote above.

• Init.d script gets return code 1 when calling itself, how can I get output?

  - by Per

  My question is, how can I modify the script so that it will tell me what goes wrong? The scenario is this: I'm trying to get Sonatype Nexus to start as a service in Ubuntu 10.04, and it just will not work. (I'm not looking for help on how to run Nexus, but on how to get some useful output from a script) It works when invoking it with sudo /etc/init.d/nexus start but fails when using sudo service nexus start I have run the update-rc.d command on it, and done everything according to instructions. The nexus init.d-script has a point where it calls itself when it detects that it should run as another user ('nexus'): su -m $RUN_AS_USER -c "\"$REALPATH\" $2" which expands to su -m nexus -c '"/opt/nexus-2.0.2/bin/jsw/linux-x86-64/nexus" start' when adding the -x debug flag to the script. This command results in return code 1. It never executes - I've set -x debug flag on the script, placed echo commands with redirect to file at the start of script to trace, etc. I cannot get any output telling me why the command will not execute. I've tried appending redirect to file after the above script line, inside the quotes, outside, any way I could imagine. All info I can get is by inserting a line echo $? after the su line, which outputs '1'. Is there a way I can see what happens when the su command runs?

• Installing Ubuntu Server 12.04 as a software RAID 1 mirror fails to boot

  - by Jeff Atwood

  I'm installing a few new Ubuntu Server 12.04 LTS servers, and they have two 512 GB SSDs. I want them to use software RAID 1 mirroring, so I was following this document religiously step by step: https://help.ubuntu.com/12.04/serverguide/advanced-installation.html To summarize the above official documentation: to set up a software RAID 1 mirror in Ubuntu Server, you choose manual partitioning during the setup, and do this on each drive: "swap" partition of roughly RAM size "physical volume for RAID" partition for remaining drive size After that, you set up the RAID 1 mirror using the RAID partitions on drive A and B, make it ext4 and containing the root filesystem partition. Setup continues from there just fine. One caveat: I was completely unable to select the "physical volume for RAID" as bootable. When I tried to do that in setup, it had no effect: I could press enter on the "make bootable" option all day long and nothing would ever change. However, after install successfully completes, I have a big problem: the system won't boot! I get Reboot and Select proper boot device or Insert Boot Media in selected Boot device and press a key What did I do wrong? Why can't I mark that "physical volume for RAID" partition bootable during Ubuntu Server setup? Is there some way for me to make the physical volumes for RAID bootable after the fact, perhaps from a live CD or something?

• Can higher-order functions in FP be interpreted as some kind of dependency injection?

  - by Giorgio

  According to this article, in object-oriented programming / design dependency injection involves a dependent consumer, a declaration of a component's dependencies, defined as interface contracts, an injector that creates instances of classes that implement a given dependency interface on request. Let us now consider a higher-order function in a functional programming language, e.g. the Haskell function filter :: (a -> Bool) -> [a] -> [a] from Data.List. This function transforms a list into another list and, in order to perform its job, it uses (consumes) an external predicate function that must be provided by its caller, e.g. the expression filter (\x -> (mod x 2) == 0) [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] selects all even numbers from the input list. But isn't this construction very similar to the pattern illustrated above, where the filter function is the dependent consumer, the signature (a -> Bool) of the function argument is the interface contract, the expression that uses the higher-order is the injector that, in this particular case, injects the implementation (\x -> (mod x 2) == 0) of the contract. More in general, can one relate higher-order functions and their usage pattern in functional programming to the dependency injection pattern in object-oriented languages? Or in the inverse direction, can dependency injection be compared to using some kind of higher-order function?

• How to pass one float as four unsigned chars to shader by glVertexPointAttrib?

  - by Kog

  For each vertex I use two floats as position and four unsigned bytes as color. I want to store all of them in one table, so I tried casting those four unsigned bytes to one float, but I am unable to do that correctly... All in all, my tests came to one point: GLfloat vertices[] = { 1.0f, 0.5f, 0, 1.0f, 0, 0 }; glEnableVertexAttribArray(0); glVertexAttribPointer(0, 2, GL_FLOAT, GL_FALSE, 2 * sizeof(float), vertices); // VER1 - draws red triangle // unsigned char colors[] = { 0xff, 0, 0, 0xff, 0xff, 0, 0, 0xff, 0xff, 0, 0, // 0xff }; // glEnableVertexAttribArray(1); // glVertexAttribPointer(1, 4, GL_UNSIGNED_BYTE, GL_TRUE, 4 * sizeof(GLubyte), // colors); // VER2 - draws greenish triangle (not "pure" green) // float f = 255 << 24 | 255; //Hex:0xff0000ff // float colors2[] = { f, f, f }; // glEnableVertexAttribArray(1); // glVertexAttribPointer(1, 4, GL_UNSIGNED_BYTE, GL_TRUE, 4 * sizeof(GLubyte), // colors2); // VER3 - draws red triangle int i = 255 << 24 | 255; //Hex:0xff0000ff int colors3[] = { i, i, i }; glEnableVertexAttribArray(1); glVertexAttribPointer(1, 4, GL_UNSIGNED_BYTE, GL_TRUE, 4 * sizeof(GLubyte), colors3); glDrawArrays(GL_TRIANGLES, 0, 3); Above code is used to draw one simple red triangle. My question is - why do versions 1 and 3 work correctly, while version 2 draws some greenish triangle? Hex values are one I read by marking variable during debug. They are equal for version 2 and 3 - so what causes the difference?

• tar - exclude certain files

  - by Alan

  I wish to tar all files in a directory and its subdirectories that do NOT end in .jpg, .bmp, .gif, or png. So, given the following folders and files: foo/file.txt foo/file.gif foo/bar/file foo/bar/image.jpg I want to tar only the files file.txt and file. file.gif and image.jpg should be ignored. I would also like to maintain the folder structure. My first thought was to pipe the results of the find command in conjunction with grep -v ".jpg|.gif|.bmp.png" to a text file, and then use the tar include argument to feed it that list of files. However, the results of the grepped find command also contain directories (in the example above, it would be "foo" and "foo/bar"), and when a directory is fed to tar, it includes all files in that directory, so I would end up with a tar file containing all of the files--not what I want. Is there any way to prevent find from outputting directories? Is there a far easier way to approach this?

• two-part dice pool mechanic

  - by bythenumbers

  I'm working on a dice mechanic/resolution system based off of the Ghost/Echo (hereafter shortened to G/E) tabletop RPG. Specifically, since G/E can be a little harsh with dealing out consequences and failure, I was hoping to soften the system and add a little more player control, as well as offer the chance for players to evolve their characters into something unique, right from creation. So, here's the mechanic: Players roll 2d12 against the two statistics for their character (each is a number from 2-11, and may be rolled above or below depending on the nature of the action attempted, rolling your stat exactly always fails). Depending on the success for that roll, they add dice to the pool rolled for a modified G/E style action. The acting player gets two dice anyhow, and I am debating offering a bonus die for each success, or a single bonus die for succeeding on both of the statistic-compared rolls. One the size of the dice pool is set, the entire pool is rolled, and the players are allowed to assign rolled dice to a goal and a danger. Assigned results are judged as follows: 1-4 means the attempted goal fails, or the danger comes true. 5-8 is a partial success at the goal, or partially avoiding the danger. 9-12 means the goal is achieved, or the danger avoided. My concerns are twofold: Firstly, that the two-stage action is too complicated, with two rolls to judge separately before anything can happen. Secondly, that the statistics involved go too far in softening the game. I've run some basic simulations, and the approximate statistics follow: 2 dice (up to) 3 dice (up to) 4 dice failure ~33% ~25% ~20% partial ~33% ~35% ~35% success ~33% ~40% ~45% I'd appreciate any advice that addresses my concerns or offers to refine my simulation (right now the first roll is statistically modeled as sign(1d12-1d12), where 0 is a success).

• Ubuntu-Java Installation-Topcoder-“Java not found”

  - by hakuna121

  I realized that this might be the dumbest question here, but being a total beginner as I am, I really couldn't figure it out after trying all kinds of instructions I could found on the web. Specs: Ubuntu 13.04; What I intended to do: check out the Algorithm Competition section, by clicking the second-to-left tab,located on the top-left of the page: http://community.topcoder.com/tc What I got: a pop-up saying Java not found! Java could not be automatically detected on your machine. This page will attempt to automatically install Java and Java Web Start. If the download and installation does not occur automatically, click the link below to go to the Sun website where you can download the latest version of Java. What I did: I followed instructions on this Ubuntu Documentation page: https://help.ubuntu.com/community/Java and installed OpenJDK(Java Runtime Environment/Browser plugin/SDK) through Ubuntu Software Center. Then I rebooted the system, tried the page again. But I still got the java not found pop-up described above. Question: What's missing the get this working? Thank you!

• How to determine main movie DVD track before ripping via mencoder

  - by Ampp3

  Maybe there's a simple answer for this, but when looking at the files on a DVD (IFOs, VOBs,etc), is there a way to easily determine the longest/main track? I'm trying to automate the process of finding the main movie track on a DVD and am running into issues. I thought this could be done by finding the BIGGEST track (look through VTS_XX_N.VOB files, where XX is the track number, and find the track with the largest filesize (sum sizes of VOB files for that track)), but apparently that isn't correct. One DVD had track 7 as the largest track (by my method), but mencoder didn't produce the correct output with this track, but worked with track 9 instead. Am I missing something? EDIT: I've heard of the utility 'lsdvd' for getting track information, but I was hoping to avoid compiling this, and use a basic method instead (ie: what I tried above). Does anyone have any idea WHY my idea didn't work?

• Horse Drawn Fiber Optics Bring Broadband to Remote Areas

  - by Jason Fitzpatrick

  When you think of fiber optics and high speed internet the last thing you likely think of is… horses. Yet horses have been put to use rolling out fiber optics to remote rural locations. In Vermont a Belgium draft horse named Fred, seen in the photo above being tended by his handler Claude, is a distinctly 19th century solution to a 21st century problem; how to run fiber optic cable through remote areas where trucks cannot easily pass. The man and animal are indispensable to cable and phone-service provider FairPoint Communications because they easily can access hard-to-reach job sites along country roads, which bulky utility trucks often cannot. “It just saves so much work – it would take probably 15 guys to do what Fred and Claude can do,” said Paul Clancy, foreman of a line crew from FairPoint. “They can pull 5,000 feet of cable with no sweat.” You can read more about the use of draft horses to draw lines and the roll out of broadband to rural Vermont at the link below.

• Difference between tc qdisc and netdev_max_backlog

  - by Mediocre Gopher

  I'm wondering what the difference between these two things on linux is. According to the docs tc qdisc can be used to set the queue size for egress and ingress packets coming in and out of the NIC (or that's how I understood it). But from what I understand netdev_max_backlog can also be used to set this. If I were to set both of them which would be used? Or are there actually two queues that are being manipulated in this case? If there are two queues, which queue is above the other (if the application is at the top and the hardware at the bottom)?

• AS3 How to check on non transparent pixels in a bitmapdata?

  - by Opoe

  I'm still working on my window cleaning game from one of my previous questions I marked a contribution as my answer, but after all this time I can't get it to work and I have to many questions about this so I decided to ask some more about it. As a sequel on my mentioned previous question, my question to you is: How can I check whether or not a bitmapData contains non transparent pixels? Subquestion: Is this possible when the masked image is a movieclip? Shouldn't I use graphics instead? Information I have: A dirtywindow movieclip on the bottom layer and a clean window movieclip on layer 2(mc1) on the layer above. To hide the top layer(the dirty window) I assign a mask to it. Code // this creates a mask that hides the movieclip on top var mask_mc:MovieClip = new MovieClip(); addChild(mask_mc) //assign the mask to the movieclip it should 'cover' mc1.mask = mask_mc; With a brush(cursor) the player wipes of the dirt ( actualy setting the fill from the mask to transparent so the clean window appears) //add event listeners for the 'brush' brush_mc.addEventListener(MouseEvent.MOUSE_DOWN,brushDown); brush_mc.addEventListener(MouseEvent.MOUSE_UP,brushUp); //function to drag the brush over the mask function brushDown(dragging:MouseEvent):void{ dragging.currentTarget.startDrag(); MovieClip(dragging.currentTarget).addEventListener(Event.ENTER_FRAME,erase) ; mask_mc.graphics.moveTo(brush_mc.x,brush_mc.y); } //function to stop dragging the brush over the mask function brushUp(dragging:MouseEvent):void{ dragging.currentTarget.stopDrag(); MovieClip(dragging.currentTarget).removeEventListener(Event.ENTER_FRAME,erase); } //fill the mask with transparant pixels so the movieclip turns visible function erase(e:Event):void{ with(mask_mc.graphics){ beginFill(0x000000); drawRect(brush_mc.x,brush_mc.y,brush_mc.width,brush_mc.height); endFill(); } }

• Where do Outlook folders go when moved?

  - by balexandre

  I have an account with external user mailboxes opened and accidentally I have moved a folder and now I can't find it anywhere. Action: I clicked on a folder and dragged it into another one. Result: Can't find the moved folder anywhere The above picture is the folders I currently have from my Outlook 2010 (via Exchange 2010), under an AD Network. Where can I (me, having admin rights over the network) retrieve that missing folder again? Attempts: The original and the one folder I need was accidentally moved, but I have created a poi folder and tried the same way, and I got the same result... the folder went missing. I also tried to reboot the client machine and access the same mailbox from OWA ... no luck on both attempts :( Any ideas on how I can retrieve the missing folder and its emails again?

• The Most Ridiculous Computer Cameos of All Time

  - by Jason Fitzpatrick

  For the last half century computers have played all sorts of major and minor roles in movies; check out this collection to see some of the more quirky and out-of-place appearances. Wired magazine rounds up some of the more oddball appearances of computers in film. Like, for example, the scene shown above from Soylent Green: Spoiler alert: Soylent Green is people! But that’s not the only thing we’re gonna spoil. Soylent Green is set in 2022, and at one point, you’ll notice that a government facility is still using a remote calculator that plugs into the CDC 6600, a machine that was state-of-the-art in 1971. Come to think of it, we should scratch this from the list. This is pretty close to completely accurate. Hit up the link below to check out the full gallery, including a really interesting bit about how the U.S. Government’s largest computer project–once decommissioned and sold as surplus–ended up on the sets of dozens of movies and television shows.

• Dual Boot menu with Ubuntu and Windows 8 not showing up

  - by user180630

  I know a lot of posts have been written, and I had read most of them when I encountered the problem. None of them solved the problem. I have successfully installed Ubuntu 12.04 on top of Windows 8. Now my PC simply boots into Windows 8. If I press 'Esc' at start of BIOS, and then F9,the GRUB shows up and Ubuntu is listed at the top of the several options to boot from. I did run Boot-Repair once I logged into Ubuntu explicitly from GRUB as mentioned above. I did all said by Stormvirux in this link but was still unsuccessful. The debug info is listed here. Something which confuses me is the message which Boot-Repair stated after it did its job. You can now reboot your computer. Please do not forget to make your BIOS boot on sda (8004MB) disk! The boot files of [The OS now in use - Ubuntu 12.04.2 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, 200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition) I don't know why it says it is far from the start of the disk as I see it first in the GRUB menu which comes up at startup. One more input, when I try to place the GRUB in sda, Boot-Repair does not progress giving me the following error: GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again. Alternatively, you can retry after activating the [Separate /boot/efi partition:] option. I had to select Separate /boot/efi partition: sdb2

• Xmodmap configuration

  - by Krishna S

  On my Debian Linux machine Ctrl+Alt+F1 is bound to a virtual terminal. I can see the corresponding entry by running xmodmap -pke keycode 67 = F1 XF86_Switch_VT_1 F1 XF86_Switch_VT_1 Per this thread, which I might add is consistent with what I've read elsewhere, the columns on the right hand side of = correspond to key, Shift+key, AltGr+key and Shift+AltGr+key. Given that, I don't understand how the keycode mapping for F1 (above) works for Ctrl+Alt+F1. It seems it should really be either Shift+F1 or Shift+AltGr+F1? Here's the output of xmodmap -pm on my machine: shift Shift_L (0x32), Shift_R (0x3e) lock Caps_Lock (0x25) control Control_L (0x42), Control_R (0x69) mod1 Alt_L (0x40), Alt_R (0x6c), Meta_L (0xcd) mod2 Num_Lock (0x4d) mod3 mod4 Super_L (0x85), Super_R (0x86), Super_L (0xce), Hyper_L (0xcf) mod5 ISO_Level3_Shift (0x5c), Mode_switch (0xcb) Can anybody explain it?

• greengeeks drupal install imagemagik 'path /usr/bin/convert' does not exists error

  - by letapjar

  I just signed up with greengeeks. I have a drupal install (6.19) on my public_html directory. The ImageMagic Toolkit can't find the binary - the error I get is "the path /usr/bin/convert" does not exist. when I use a terminal and do 'which convert' it shows /usr/bin/convert also, I have a second drupal install in an addon domain - it's home directory is above the public_html directory (in a directory called '/home/myusername/addons/seconddomain') The drupal install in the addon domain finds the imagemagick binary just fine. I am at a total loss as to why the original install cannot find the binary. The tech support guys at greengeeks have no clue either. Any ideas of things to try?

• Automation Question using VMWare Workstation

  - by James K

  I'm running an experiment that requires me to create 100 instances of Windows XP w/SP3 and saving each VM instance off to a hard drive. I have to annotate the time that the VM load starts (starting my timer when I see the "Setup is preparing...") until the load ends when I see the final desktop after VM loads its drivers. I also have to annotate the host start and stop time. Is there any way this process can be automated? Each load runs me about 16:00 minutes and gets real tiresome after a time. BTW... Exact timing is not necessary, eyeballing as described above is sufficient for my testing needs.

• What's static.ak.fbcdn.net that appears on the status bar of my browser everytime Facebook is loading?

  I find the message: "waiting for static.ak.fbcdn.net..." on the status bar of my browser everytime I load Facebook and many a times even while loading other websites. I searched on net and found out that static.ak.fbcdn.net stands for static akamai facebook content delivery network. I reckon that static.ak.fbcdn.net is the server URL from where Facebook delivers contents to our browser. Am I right? Can anyone elaborate? Also, why does the above mentioned message appear while loading other websites too?

• TraceTune: Larger Files and History

  - by Bill Graziano

  I updated TraceTune over the weekend.  I increased the trace file upload size to 20MB.  We’ve processed over half a million rows of trace data so far and I’m confident this won’t kill the server. I added average CPU and average disk reads to the screen that lists the SQL statements in a trace file. I only added these two.  I’m pretty sure average writes isn’t that import.  I’m still thinking about average duration.  I’m trying to balance showing you what you need with a clean, simple interface.  Plus I have a way to see the averages that I describe further down. TraceTune now keeps the last 10 files that you’ve uploaded and will give you some basic details about each file. I think the last change I made is the most interesting. For each SQL statement, I show the history of that statement. You’ll see each trace file where this statement was found.  It will list the averages for CPU, reads, writes and duration.  This will quickly show you if you’re improving the performance of that query.  In my screen shot above you can that even though the execution counts are very different the averages are consistent. If you want to see what queries are consuming the most resources on your server give TraceTune a try.

• General List of Common Programming Errors

  - by javamonkey79

  As one journey's from apprentice to journeyman to master I've noticed that one accumulates a list of best practices for things they've been bitten by. Personally, I write most of my stuff in java & SQL so my list tends to be slated towards them. I've accumulated the following: When doing list removal, always reverse iterate Avoid adding items to a list you are currently iterating on Watch out for NullPointerExceptions Now, I know there are language specific "common errors" links out there like this one. And I'm also aware of the pragmatic programmer tips, Martin Fowler's "code smells". Does anyone know of any good lists out there of things like I've listed above (re: list removal, adding items, etc). My guess is that there are some good QA folks out there that can probably throw me a bone here. I'm not looking for things the compiler can catch - I'm looking for common things that cause bugs. In the event that there isn't a list out there already then I welcome posting your own findings here. Thanks in advance!
