• What is a good programmer's desk? [closed]

  - by Jim

  I'm building a home office and looking for the ultimate desk. Lot's of resources about the great desk chairs, but very little on great modern desks. Requirements: Straight. No side cabinets. Attractive. Electric adjustable would be nice, but I haven't found very attractive looking one. The one recommended in this thread is pretty ugly. The Herman Miller Sense desk looks nice. Big fan of Herman Miller after my Aeron and Mirra. Does anyone have any experience with their desks? EDIT: Thanks all for the advice. I ended up just going with the Galant after seeing it and the Herman Miller's in person. What a great desk!

• Linux router and firewall with IP accounting

  - by Andrew

  I'm working on a project to replace my organisation's aging Slackware gateway/router/firewall machine in our colo rack. Previously we used rc.firewall but we are now looking for something more modern and easily configurable. The requirements are: Act as a gateway router & firewall Port forwarding to a Terminal Server in the colo IP/traffic accounting, preferably accessible via SNMP (already using cacti for other servers) Possibility of acting as a PPTP server & routing these connections Is not an out-of-the-box Cisco product (don't have the finances or support to maintain it) I'd prefer to use Ubuntu or some other Debian-based distro but something that integrates everything we're looking for is certainly an option if it offers all the desired features and is easy to configure. Is there a simple set of packages that will provide me with the Firewall & Accounting features, or am I best served with a custom-built distro / other solution?

• In Ubuntu, how do I change my default Greek font?

  - by Matthew

  I'm taking a course in ancient Greek, and I store notes and flash cards on my computer. However, by default Ubuntu uses a modern Greek font. This changes some noticable things--for example, a circumflex is ? instead of a?. I can type the circumflex by switching back to english and entering the unicode combining character u0311 (which is what I just did to type the second a), but obviously this is very cumbersome. I've installed the "ttf-linex" package from the Ubuntu repositories, which claims to include an ancient Greek font. But I have no idea how to enable this font for whenever I switch to the Greek keyboard layout.

• Configuring Apache for multiple clients

  - by Chris_K

  Last week I had a question here about suexec / suphp but I tried to accomplish too much. I'm going to narrow the scope a bit and try again. I'd like to configure a LAMP server to host multiple clients. I'd like it to seem (from the client's viewpoint) just like any other shared hosting environment. Web sites in their home directory, no need to muck around with file ownerships to get pages served, etc. It would seem that a configuration that involves suexec and suphp is the way to go(?) I'm specifically looking for a current/modern guide on how to accomplish this (I'll be using CentOS if it matters) and I'm afraid I need more than a link to Apache docs. Are there any good How-To's out there? The few I've found have been pretty out of date, but it is quite possible my search was weak.

• What are the best options for a root filesystem hosted on SSD under Linux

  - by stsquad

  I'm working on an embedded system which is going to be booting and hosting it's rootfs on an SSD disk. We are currently looking at using Intel X-18M SSDs. The file system structure will have a fairly static /usr section (modulo software upgrades) and an active /var and /var/log for maintaining state and logging. Given the wear-levelling done by the underlying flash does having separate partitions help or hinder? As modern SSDs appear as straight block devices and hide their mapping magic behind their firmware is there any point trying to optimise the choice of file-system that sits on-top of the SSD? Finally does enable SMART monitoring make any sense in this context or are their SSD specific ways of determining the underlying health of the storage hardware?

• How to align text at the top left-hand corner?

  - by OverTheRainbow

  I'd like to use stylesheet instead of hard-coding HTML so that text within cells are aligned vertically, ie. text starts at the upper left-hand corner. However, neither of this works: <head> <link rel="STYLESHEET" href="display.css" type="text/css"> <style> td {vertical-align:top; font-size:x-small} td {vertical-align:text-top; font-size:x-small} </style> </head> Does someone know? Thank you. Edit: Problem solved. Turns out the HTML editor I'm using is a bit old and didn't display things as expected, but they do show OK in a modern browser with "vertical-align:top".

• In *nix, how to determine which filesystem a particular file is on?

  - by smokris

  In a generic, modern unix environment (say, GNU/Linux, GNU/Solaris, or Mac OS X), is there a good way to determine which mountpoint and filesystem-type a particular absolute file path is on? I suppose I could execute the mount command and manually parse the output of that and string-compare it with my file path, but before I do that I'm wondering if there's a more elegant way. I'm developing a BASH script that makes use of extended attributes, and want to make it Do The Right Thing (to the small extent that it is possible) for a variety of filesystems and host environments.

• CCD vs. CMOS webcams

  - by rob

  Several years ago, I tried a CMOS-based webcam and it really sucked. It needed an extremely brightly-lit room to work. Around the same time, I also tried a CCD camera and it worked great. But since then, I've heard that CMOS technology has advanced considerably. Is it still the case that CCD webcams will give you a better picture, or can CMOS webcams also produce a picture of similar quality at moderate to low light levels? What type of camera is used in modern integrated webcams and cameras? If CMOS cameras actually are competitive these days, how do you tell if a webcam has a newer-generation CMOS sensor instead of one of the older sensors?

• Chrome - SSL Security issue on Windows platforms?

  - by al nik

  Fortify.net is a service that displays what's the currently encryption key used by your browser in a https connection. If I browse this site with Chrome 4.1.249.1042 in WinXp SP3 the key used is RC4 cipher, 128-bit key This encryption is weak, and it's the one used by old browsers like IE6. Chrome works fine on Fedora9 and it uses AES cipher, 256-bit key as more modern browsers do (i.e.Firefox) I consider this a security issue. I'm considering to switch back to Firefox in Windows. Do you know if it's possible to change the default encryption key in Chrome?

• How can I create a hotkey to play/pause Pandora on OS X?

  - by etlovett

  I'm on OS X and want to have a hotkey (e.g. Cmd-Opt-P) to play/pause Pandora. I've used Butler to set one up for iTunes, but can't find a comparable solution for Pandora. I'm open to any solution (including apps, AppleScripts, etc.) that would allow me to bind a hotkey to play/pause, and I'm willing to use a paid solution as well. What can I do? Solutions I've looked into and/or tried: Pandora Boy: but the keyboard shortcuts don't seem to work for me, despite following the instructions here. The official Pandora One player: according to the comments on this Pandora blog post, it doesn't support hotkeys. My system: OS X 10.6.6 Each of the various truly-modern browsers Flash 10.1

• Why would you use EAP-TTLS instead of PEAP?

  - by Ivan Macek

  As I understood EAP-TTLS and PEAP share same level of security when implemented in wireless networks. Both only provide server side authentication via certificate. The drawback of EAP-TTLS can be non native support in Microsoft Windows so every user has to install additional software. The benefit of EAP-TTLS can be support for less secure authentication mechanisms (PAP, CHAP, MS-CHAP) but why would you need them in modern and properly secure wireless system? What are you opinions? Why should I implement EAP-TTLS instead of PEAP? Let's say that I have most Windows users, medium Linux users and least iOS, OSX users.

• OneNote can't connect to SkyDrive in Windows 8.1

  - by Greg

  Since I installed windows 8.1 I can't open my OneNote notebooks stored on skydrive with the 2013 Office OneNote app. When I click in the office app to open from skydrive it gives back: "We can't get your notebooks right now. Please try again later." I can open them without trouble in the modern UI onenote app, but I can't open password protected pages there. Also if I try to open it from a browser the error message follows: "We couldn't open that location. It might not exist or you might not have permission to open it." Neither can I create new notebooks on skydrive with the office app. "...The specified location is not available. -You do not have permissions to modify the specified location..." Can it be fixed somehow? Or can I at least save a notebook to my hard drive without opening it in office? The backup file got deleted with the win 8.1 installation.

• How to scan and annotate documents and receipts so metadata is searchable and embeddeded in document

  - by Precipitous

  I'm getting tired of living in the modern age and still having a messy filing cabinet full of paper. I have a nice cheap scanner and want to scan receipts, warrenties, and so forth. To make it possible to find these, I'd like to make them searchable via Windows Search (or google desktop search). Because I'm lazy with backups, I want a file format that embeds metadata into the file. Backups should be as simple as coping a bunch of image files around. I'm also cheap, and am not going to install an expensive solution. I'm hoping one of the basic formats can do this. So, what common scannable format satisfies: searchable and and metadata embedded in image generated. The more "open" and portable the better.

• PS/2 vs USB keyboards: performance and energy consumption

  - by Mister Smith

  As far as I know, PS/2 keyboards are interrupt driven, while USB are polled. Typically a PS/2 keyboard was assigned IRQ_1 on Windows. I'm no hardware expert, but at a first glance seems like the PS/2 keyboards are more efficient. So here are my questions: On modern day computers, are PS/2 keyboard better (or faster), and if so, would it be noticeable at all? (e.g.: in gaming) Since they don't need polling, do PS/2 keyboards save energy compared to USB? (notice I'm not talking only about the peripheral here, but about the overall computer energy consumption). In case PS/2 had any advantage over USB, would adding a PS/2 adapter to my USB keyboard make the device as good as an actual PS/2 keyboard? Conversely, would adding a USB adapter to a PS/2 make it as bad as a USB KB? Thanks in advance.

• Non-Windows, non-Unix-like OS's?

  - by dsimcha

  Since most operating systems I've heard of besides Windows seem to derive their heritage from Unix, I've been curious whether any OS's with the following characteristics exist: Not generally considered Unix-like, i.e. wasn't designed with Unix compatibility as a primary goal, doesn't use X11 as its default GUI in the most common distributions, doesn't support Unix commands by default, etc. Not in the Windows NT family. Is a modern production operating system, not a purely legacy operating system, a research/hobby project or an OS that's still in an alpha state. Is targeted at commodity x86/x64 PC hardware.

• Is there no such thing as a Gigabit switch?

  - by Torben Gundtofte-Bruun

  According to the manufacturer specification, even my rather plain desktop computer has "Gigabit Ethernet". So when I want to copy large files over the LAN (not Internet) it would make sense to have a gigabit switch. I'm searching eBay for a gigabit switch for a planned home network upgrade. The products I find are all labeled "gigabit" but they all have 24 x 10/100Mbit autosensing ports and sometimes 2 x 10/100/1000Mbit autosensing ports. It was my understanding that 10/100 is ancient and that modern computers have network interfaces that work with 1000Mbit, so it would make sense to get a switch that has 24 x 1000Mbit ports. Did I misunderstand, or are sellers (deliberately?) mislabeling older hardware? (Let's not dive into wired vs. wireless networks and how "N" wireless is fast. You'd be right, but not answering the question.)

• What technical reasons exist for not using space characters in file names?

  - by Chris W. Rea

  Somebody I know expressed irritation today regarding those of us who tend not to use spaces in our filenames, e.g. NamingThingsLikeThis.txt -- despite most modern operating systems supporting spaces in filenames. Are there technical reasons that it's still common to see file names without (appropriate) spaces? If so, what are these technical reasons that spaces in filenames are avoided or discouraged, and in what circumstances are they relevant? The most obvious reason I could think of, and why I typically avoid it, are the extra quotes required on the command line when dealing with such files. Are there any other significant technical reasons?

• Is it safe to run an operating system from an USB flash drive?

  - by Georg

  I've got a laptop that has a broken harddisk controller. Replacing the motherboard is quite expensive. I thought about buying a flash drive and installing & running the system from it. However, I'm concerned about some things. Speed: Are they fast enough for swap memory (I've got only 1GB RAM installed.) I'm considering buying 2 or 3 of them and making them into a RAID. What about limited write cycles? How long will it last for a system that has a filesystem with journaling enabled? I'd hate to abandon it. Are there significant differences between internal SSD which are used in modern laptops like MacBooks and USB flash drives? What should I expect in 10 years when the memory wear starts kicking in?

• 2.5" SSD in a 3.5" desktop drive bay normal?

  - by Cory Petosky

  I'm a little out of touch with modern desktop builds, but I recently built a new machine anyway. I want to pick up a SSD for my I/O intensive apps (EverQuest 2 and Flash CS4 mostly), but I'm having trouble finding any in the 3.5" form factor. Is this expected, or do I fail at product search? And, if it is expected, do 2.5" SSDs come with an adapter to fit them in my desktop machine, or will I need to purchase one separately? And, finally, if I do need to purchase an adapter, are they pretty standard or are some better than others. General advice is most welcomed, though specific product recommendations in addition would be helpful!

• Why is hibernation still used?

  - by Moses

  I've never quite understood the original purpose of the Hibernation power state in Windows. I understand how it works, what processes take place, and what happens when you boot back up from Hibernate, but I've never truly understood why it's used. With today's technology, most notably with SSDs, RAM and CPUs becoming faster and faster, a cold boot on a clean/efficient Windows installation can be pretty fast (for some people, mere seconds from pushing the power button). Standby is even faster, sometimes instantaneous. Even SATA drives from 5-6 years ago can accomplish these fast boot times. Hibernation seems pointless to me when modern technology is considered, but perhaps there are applications that I'm not considering. What was the original purpose behind hibernation, and why do people still use it? Edit: I rescind my comment about hibernation being obsolete, as it obviously has very practical applications to laptops and mobile PCs, considering the power restrictions. I was mostly referring to hibernation being used on a desktop.

• New video card? [closed]

  - by TutorialPoint

  I ran into some problems with my ATI Radeon x1200. I want it to support vertex shader 3.0, but it only does 2.0. This is because Call of Duty: Modern Warfare 2 only works with 3.0. So, I want a new video card. Can someone help me, with a more clean look to it? I bet if I would stick to some seller, I would end up with a video card that does not support what I want, or is too expansive. I really do not want it to be above $75, if possible. Some info about my PC: Manufacter: XXODD Processor: AMD Athlon64 X2 DualCore 4000+ 2Ghz (but running currently 32 bit OS) ATI Radeon X1200 video card (the problem) 1 GB RAM DDR2 MS-7367 Motherboard Windows 7 Ultimate OS 32-Bit Build 7600 RTM

• What is the simplest way to confirm or to disprove that Virtual Box virtual machines support GRE protocol

  - by mbaitoff

  It is stated in VirtualBox manual (chapter 6) that VM network interfaces in "NAT" mode do not support GRE protocol. I'm currently trying to setup a pair of VMs as pptp server and client which would communicate via VM's network interfaces in "INTERNAL NETWORK" mode. I set up modern Linux OSes with pptp software on both machines and made some basic pptp configuration. However, I fail to connect the client to the server - server reports a failure when writing to GRE socket. I now need a quick proof of principal ability to use the GRE protocol between VirtualBox VMs over a network in "INTERNAL" mode, such as a several-line .c program that would try to open/send/receive/close a GRE protocol connection, or like a specific lightweight tool to diagnose the GRE availability. Any suggestions?

• GNOME/KDE Linux entirely in RAM?

  - by František Žiacik

  Hi. I'd like to have very responsive linux but I also like modern, elegant and functional desktops like gnome or kde, not the lightweight ones like xfce or lxde. Once I tried PuppyLinux and was impressed by the responsivity when I clicked an application. In my Ubuntu, it bothers me much when I click chromium and must wait 5 seconds of disk flashing until main window appears. Or evolution or anything else. Is it possible to make GNOME or KDE run entirely in RAM like PuppyLinux (of course, I mean frequently used applications and services, not all) if you have enough of it? I don't care if boot time is longer. I tried using "preload" but it didn't help much.

• Do most front and rear USB connections deliver the same power and performance?

  - by Bratch

  I was reading this Three Monitors For Every User and there were some comments about rear USB ports being able to deliver more power than front USB ports because they are directly connected to the motherboard and closer to the power supply (by circuit board runs). Even though the front USB ports may have connectors farther from the power supply, and there are cables from the motherboard to the front ports, I think that the difference in power would be negligible (unless the case is over 5 meters long). Anyone know for sure if they are the same or different? Note that I'm not talking about an older case where the front might have been USB 1.1 and the rear USB 2.0. A modern case would have USB 2.0 on all ports. And of course using a powered hub would deliver plenty of power.

• Does the upload file INPUT HTML element give any personal information away?

  - by Senseful

  I'm wondering what personal information the file input (<input type="file">) element gives the website. I noticed that it does show the file name and the website does seem to have access to it. What about the file's path? If the file is located in My Documents, they could find out the user name via the path (e.g. C:\Documents and Settings\Bob\My Documents) which many times is the actual user's name that is using the website. What information do most modern browsers allow the website to access when a user uses the file input element? Could JavaScript somehow be used to gain more information? What about when plugins (such as Flash or Java) implement file uploading?
