• Where should I go to learn about networking? [closed]

  - by Ollie Saunders

  I wonder if anyone could recommend resource or resources such as a good book that: explains how all the important protocols work and interact. I’m interested in those that are relevant in a typical home network and used over the Internet explains in detail how ADSL Internet connections work to the level of depth necessary so that I’m able to tweak and measure performance settings starts from the beginning but attempts to provide proper understanding rather than idiot-oriented steps to follow Basically, I’m interested in how these technologies work and tend to be implemented in hardware and software rather than “here’s what to do if…” I’m interested in Computer Networking by Andrew S. Tanenbaum and I wonder if anyone else has any experience with that title. It’s expensive but I could probably loan a copy for £3 from the library or so.

• FTP error when doing file transfer

  - by Ernie

  I'm running vsftpd version 3.0.2 over FTPeS, and I'm having a bit of trouble with file transfers. It seems to work fine when I'm on the LAN, but not from an external IP address. I have the control port and data ports open on my server's software firewall and my router's firewall. When I'm using the service from an external IP address, it seems like sometimes a file transfer will complete, but it times out and I always get the client error: "426 Failure writing network stream". I've tried several clients. I'm thinking there is some sort of data sabotage either at the router or some server policy; maybe because I'm using passive ftp? Suggestions?

• How to batch rename files copied from OSX to Windows with ':' in filenames?

  - by tputkonen

  This is really puzzling. I have lots of videos that were stored using Mac OS, and now I have to edit them on Windows XP. I copied files using HFSExplorer. Editing software refuses to open the files with their current names, and so far I have not found a way to batch rename all the files. Names of the files look like this: clip-2009-10-01 21;26;00.mov But I suspect in OSX the time was 21:26:00. I would like to replace the space with an underscore, and semicolons with dash. I've tried several bulk rename applications, with ; and :, but in vain. Also I've tried rename.pl, but also in vain.

• qmail questions - whitelisting and relays

  - by Richard

  My new server runs qmail, which I've never used before. There is no inbound mail on the server (all the clients have mail hosted elsewhere, but some systems on the server send mail. I'm about to move a client there who has several parked domains, and looking at the smtp log, the server is already blocking many attempts to relay spam using one of the parked domain names (probably because a related domain is already hosted there). How do I ensure those mails stay blocked, while allowing legitimate addresses to send out? Server OS is CentOS and hosting software is Kloxo.

• Experienced programmer, beginner at web design, tools for effective maintainable web design? [closed]

  - by Clinton

  I do quite a bit of programming in my work, which I'm comfortable with, but recently I've being trying to do some web-design for non-work related reasons. I've got a Drupal site up and running, and added some content. But they all look fairly basic. Header with some content. It doesn't look particularly polished. Anyway, as an example, what I wanted to do was make some "bubbles", each with some text in them. From a programmers point of view, say: bubble(question_text, answer_text) might expand to a box with some border, with "Question: " + question_text then "Answer: " + answer_text. Of course I'd have lots of these bubbles, but I'd like to change their look and feel in one place, so simple HTML would be a maintainable nightmare. I also want to lay them out on the screen in some fashion. I was thinking a mixture of javascript and CSS, or possibly use PHP which Drupal uses. On the other hand, I fear I might be taking a 1990s approach to this, and that there's actually tools available now that make this process a lot easier. I'm just wondering what the best approach to this sort of task is? Should I be using offline web design software and copying the code to Drupal, and if so, any recommendations? I'm sorry if my question is a bit vague, because I'm not really sure what question I should be asking. I'd appreciate if you answer and comment, and I'll try my best to be more specific as I understand more.

• 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.

• 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

• How do you map a solo press of a modifier key to its own function or mapping on Windows?

  - by Conrad.Dean

  Today on hacker news there was a clever article on custom shortcut keys. The author talks about a technique for remapping a modifier key such as CTRL to ESC if CTRL were pressed without a modifier. This is useful in vim because of how often you need to press ESC. Another technique he describes is mapping the open parenthesis, ( to the left shift key, and ) to the right shift key. If another key is pressed when shift is held down, the shift key behaves normally. The author describes the software he uses on OSX, but is there a way to do this on Windows? I've heard of AutoHotKey but it seems to only fire macros when simple keys are pressed, rather than the conditional state switch that this would require.

• Monitoring Baseline

  - by Grant Fritchey

  Knowing what's happening on your servers is important, that's monitoring. Knowing what happened on your server is establishing a baseline. You need to do both. I really enjoyed this blog post by Ted Krueger (blog|twitter). It's not enough to know what happened in the last hour or yesterday, you need to compare today to last week, especially if you released software this weekend. You need to compare today to 30 days ago in order to begin to establish future projections. How your data has changed over 30 days is a great indicator how it's going to change for the next 30. No, it's not perfect, but predicting the future is not exactly a science, just ask your local weatherman. Red Gate's SQL Monitor can show you the last week, the last 30 days, the last year, or all data you've collected (if you choose to keep a year's worth of data or more, please have PLENTY of storage standing by). You have a lot of choice and control here over how much data you store. Here's the configuration window showing how you can set this up: This is for version 2.3 of SQL Monitor, so if you're running an older version, you might want to update. The key point is, a baseline simply represents a moment in time in your server. The ability to compare now to then is what you're looking for in order to really have a useful baseline as Ted lays out so well in his post.

• How can I take browser screenshots at a higher resolution than my browser supports?

  - by Joshua Carmody

  I need to take a screenshot of a website as it would appear on a very high resolution monitor... say 4000x3000 pixels. My laptop's screen has a native resolution of 1400x768. Basically, I need to simulate having a monitor resolution much higher than my monitor and video card actually supports. I want the screenshot of the site to look pretty much how it does when you hit CTRL MINUS (zoom out) in Firefox repeatedly, but without any loss of pixels due to scaling. How can I do this? Is there some way to use virtual machine software to simulate a super-high-res display? If not, is there some way to open a browser window bigger than the screen, and then capture its contents as a PNG somehow? Anything else that might work?

• 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?

• File corruption when copying different file on raid 1

  - by Stephan

  I have a RAID 1 configuration of 2 1TB drives on a Fedora 12 box. Most of what is stored there are video files that are numerical labeled. The problem I'm having is that I had one of the video files get corrupted. I copied a replacement from a backup and replaced the bad file and now it works fine. However, after doing this the next numbered file goes from 350MB to 200KB and all but about .5 second of video disappears. If I then replace that file it happens to the next one down the line. Ex: Replace corrupt file 1.avi and file 2.avi shrinks to 200KB. Replace now corrupted 2.avi and it works but 3.avi gets screwed up. I have run SMART tests on the drives and they report fine. Does anyone have any tests I can run to try to figure out what is going on? EDIT: It is a two disk software RAID 1 with an ext4 filesystem

• Checking whether product key will work with SBS 2003

  - by Rob Nicholson

  We've recently absorbed a small company who had a Dell PowerEdge server running SBS 2003. For some reason, the hard disks have been wiped. We have the product key though from the sticker on the side of the case but not the installation media: Win SBS Std 2003 1-2 CPU 5-CAL OEM software We do have a Dell labelled set of four CDs labelled SBS 2003 in our store and I've built a VM from this media but it doesn't prompt for the product key during install. Is there any way to ascertain whether this media will work with this product key without going through activation? I know one can activate several times but would prefer to check we've got the right media before doing this. Thanks, Rob.

• 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.

• 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 =/

• I've inherited 200K lines of spaghetti code -- what now?

  - by kmote

  I hope this isn't too general of a question; I could really use some seasoned advice. I am newly employed as the sole "SW Engineer" in a fairly small shop of scientists who have spent the last 10-20 years cobbling together a vast code base. (It was written in a virtually obsolete language: G2 -- think Pascal with graphics). The program itself is a physical model of a complex chemical processing plant; the team that wrote it have incredibly deep domain knowledge but little or no formal training in programming fundamentals. They've recently learned some hard lessons about the consequences of non-existant configuration management. Their maintenance efforts are also greatly hampered by the vast accumulation of undocumented "sludge" in the code itself. I will spare you the "politics" of the situation (there's always politics!), but suffice to say, there is not a consensus of opinion about what is needed for the path ahead. They have asked me to begin presenting to the team some of the principles of modern software development. They want me to introduce some of the industry-standard practices and strategies regarding coding conventions, lifecycle management, high-level design patterns, and source control. Frankly, it's a fairly daunting task and I'm not sure where to begin. Initially, I'm inclined to tutor them in some of the central concepts of The Pragmatic Programmer, or Fowler's Refactoring ("Code Smells", etc). I also hope to introduce a number of Agile methodologies. But ultimately, to be effective, I think I'm going to need to hone in on 5-7 core fundamentals; in other words, what are the most important principles or practices that they can realistically start implementing that will give them the most "bang for the buck". So that's my question: What would you include in your list of the most effective strategies to help straighten out the spaghetti (and prevent it in the future)?

• Text comparison utility

  - by Aaron

  I know this has been asked before...but I have a spin as I have been trying out varying free software offerings. I want to rid out department of DiffDoc the problem is that I am having trouble locating something that will do what we need. WinMerge has been the latest attempt... The problem is simple. One Word doc...one PDF with a portion of it containing the text to be compared against. Compare them and be done. Raw text, ignore whitespace, ignore carriage returns, etc... Just compare the text and give me the results in some sort of report. NOTE: Have tried ExamDiff, kdiff3, Tortoise, and a few others...

• Social-network, online community, company and job reviews, salaries statistics and much more.. Do we have it? Do we need it?

  - by Vlad Lazarenko

  I have many friends from Ukraine who are programmers. So I found out that they have a web site that collects, organizes and analyzing information about IT companies, which includes location, feedbacks, company reviews from current and former employees etc. They also collect programming salaries and organize them by language, region etc. That web site is ran by programmers and for programmers, all information is absolutely public and free. Plus, web site has forums, and people can discuss (more or less social than specific programming stuff) things, publish articles, news etc. I personally think that is useful, especially for those who are new in this industry. For example, you may do a small research and find out that, for example, Java programmers getting paid more than PHP programmers but demand is lower. Or you get an offer from the company, is about to accept it, but read reviews and find out that they don't even provide internet access at work and if you need to download something, you have to ask your manager to do it for you, and managers share a single computer that has internet connection to get that stuff for you (there is only one such company in Kiev, Ukraine, called SMK, for Software Mac Kiev, a big shame). So the question is - do we have something like it in US? Or at least, say, for New York region? Or state? All information I managed to find online is inaccurate or not full. Forums are very specific. If we don't have it, would you be interested in creating such a portal? Thanks!

• Create netbook recovery image without DVD burner (virtual burner?)

  - by Dan

  I have a new Acer Aspire One which is asking to create a recovery DVD. It doesn't have a built in burner, and I don't have a USB burner. However I do have a large USB hard drive. Is there some way to get the recovery software to "burn" an image file instead of a real DVD? I know you can download a Linux recovery image, but the netbook comes with XP. I plan to install Linux on it but I'd like an XP recovery image just in case.

• Netbeans: Install/Activate/Uninstall/Deactivate plugins buttons disabled

  - by Josh

  I recently installed Netbeans 6.9 on a new computer. I went to install the NB Android plugin, which I have on another computer, but I found most of the functionality of the plugins window disabled. The install, uninstall, activate, and deactivate buttons are grayed out. I have included images at the bottom. This hasn't happened to me before, and searching Google hasn't turned up anything useful. I thought it might have been a permission problem so I tried running Netbeans with gksudo but that didn't help. I also thought it might have been something wonky with the Ubuntu Software Center install, so I uninstalled that one, and downloaded Netbeans from the main site and I installed it in my home directory, but it does the same thing. I'm running Xubuntu 10.10 and Netbeans 6.9.1 Available Plugins Tab It won't let me add more than one hyperlink due to a lack of reputation. Installed Tab - http + i.imgur.com/Nhqi4.png

• What you'd need to setup BBS?

  - by raspi

  What I need to setup BBS nowadays? I'm thinking of BBBS or PCBoard (no telnet! too new technology). What I've thinked so far, I'd need: virtual machine which runs DOS and hook that virtual COM-port to somekind of virtual VoIP modem software somehow (is there any?). How you can call to it across internet? Can you use HyperTerminal straight with that virtual/real modem? Or will VoIP just garble the modem data and nothing will work?

• Can I install new version of Ubuntu in spair RAIDed partition with unetbootin

  - by artfulrobot

  I have Ubuntu 11.04 running on my home desktop which has 2 hard drives mirrored by RAID. The drives are partitioned with a big data partition, a swap partition and a couple of 20Gb partitions for OSes, one is 11.04 which is in use, and the other is kept spare for installing a later version. Which is what I'd like to do now. The idea of a 2nd partition for new OS is that I can try it, and if it's problematic, I can boot back into the original one - the machine is shared with others, so I need it to stay available! I have had horrible problems with software RAID after using a Live USB stick - basically it messes up the internal numbering of the RAID drives or something, anyway, the result is you can't boot after using it :-( and have to spend ages re-assembling the arrays, trying to remember grub commands etc etc. Quite a shocker when you consider booting from a Live USB is supposed not to affect the existing system. As I'm installing in a RAIDed disc, I would typically use the Alternative install (sad to hear that this is going to be dropped in future). However, I think I might be able to use unetbootin to trick the system into working on top of the existing system that understands RAID, with the normal ISO? If unetbootin loads from drives that are already understood to be RAIDED, then presumably it will only see md0... instead of sda, sdb... and as long as I don't need to repartition (I don't) it should be fine, right? Or is that just plain foolishness? Please tell me before I end up with a dead system (again!)

• Simplest way to add stills to MP3 audio soundtrack

  - by Ambrose

  I have some audio and want to add visuals to it and upload to YouTube. Nothing fancy, just like slides, image_A from 00:00:00 to 00:00:05 then image_B from 00:00:50 to 00:00:30 and so on. I have recent Mac and Windows machines to do this on. I'd like to do it on free or demo software if I can. Please give a bit of a hint how to get started if you can. I took a look a iMovie, but ... where to start, if you haven't actually got video?

• How can you achieve and maintain flow while pair programming?

  - by bizso09

  Flow is a concept introduced by Mihaly Csikszentmihalyi; in short, it means to get into the "zone". You feel immersed in your task, focused; the task can be difficult but challenging at the same time. When people achieve flow their productivity shoots up. Programming requires a great deal of mental focus because we often need to juggle several things in our minds at once. Many like to work in a quiet environment where they can direct their full attention to the task. If they are interrupted, it may take several minutes or even hours to get back into flow. I understand there's a practice in agile development and extreme programming called pair programming. It means you put the whole software development team in one room so that communication is seamless. You do write code with your pair because this way you get instant code reviews and fewer bugs get through. I've always had problems achieving flow while doing pair programming because of constant interruptions. I'm thinking deep about an issue then all of sudden someone asks me a question from another pair. My train of thought is lost. How can you achieve and maintain flow while pair programming?

• Disadvantages of enabling AHCI after Win7 install

  - by Mario De Schaepmeester

  I've formatted my notebook that has a 5400RPM HDD with ~500GB capacity. After installing Windows 7 and about half the drivers (including chipset) I began to doubt whether to go for IDE or AHCI mode for my hard drive. There used to be a lot of discussion on the internet which is better and so far I understood it was particularly helpful on SSDs. Now the general consensus seems to be that AHCI mode is best for most hard drives. I have thus enabled AHCI in the middle of configuring my notebook (rest of the drivers, necessary software etc...) Two questions: considering my HDD's spec above, should I leave it on? Is there any disadvantage of enabling it after Windows 7 and chipset drivers installation? Windows 7 version is 64 bit Home Premium.
