• Which Single Source Publishing tools and strategies are available?

  - by Another Registered User

  I'm about to write a 1000-Pages Documentation about a huge programming framework. The goal is to bring this documentation online into an web platform, so that online users can search through it and read it online. At the same time, the text has to be made public in PDF format for download. And at the same time, the whole thing needs to go into a printed book as well (print on demand, they want a giant PDF file with the whole book). The PDF files: The whole content is divided into several chapters. Every chapter will be available as a standalone PDF eBook. And finally, all chapters will be available in one huge printed book. Is LaTeX capable for something like that? Can it be used for Single Source Publishing? Or would I have to take a look at other technologies like DocBook, etc.?

• Making TMUX use Alt+Num to select window

  - by Oxinabox

  I have been messing with TMUX, and I am liking the configuration abilities. The window list at the bottom makes me think that the same shortcut for changing windows in Irssi, should work in TMUX, but it doesn't. So at the moment, I have to press C-b then a number to get that window open. I am happy having C-b for my normal prefix, (eg for C-b ? for help, C-b : command entry) But it would be cool if I could use both C-b+Numkey and Alt+NumKey for changing tabs. It would be even cooler if it could detect if a window is showing Irssi, and then ignore the Alt+NumKey, so that I can still change between Irssi windows.

• Mobile CPU vs. Ultra-low CPU: performance

  - by Mike

  I'm choosing a new laptop and one of the questions is a type of CPU — mobile or ultra-low voltage. If to be more precise, I'm torn between two models of Intel Core i5 — i5-2410M and i5-3317U. Here is a comparison table. According to official specs the first-one has 2.3 GHz clock speed, while the second-one has only 1.7 GHz, that's about 25% difference. Is it really important parameter and which CPU is more preferable for a laptop for development, media and internet purposes?

• Computer loses all installed programs and appears to return OS-only state

  - by Jake

  This is a story regarding 3 laptops of different brand and models. On separate occassions, I configured each of these Windows 7 / Vista computers with the necessary configuration and applications (which are supposedly the same actually), e.g. join office domain, same windows updates, microft office etc. These machinese were configure in our office in Singapore, and then they were taken to India for use. Someday in India, when booting up the laptop, all went fine except when it reach the log in screen, it was no longer possible to login with domain credentials. Logging into the laptop local admin account will lead to discover that the machine has returned to "OS-only state". All the configurations and applications were gone. The actual user profiles are still in the C: drive so files can still be retrieved, but under Control Panel Uninstall Programs it is evident that at least the registry is corrupted. The above scenario happen to the first 2 laptops. For the third, the system reports "Operating System Not Found" on boot up. I cannot think of any reason except to suspect a power fluctuation issue. Question is, will a power issue create this behaviour? What else can cause this issue?

• Why does newline come before space in the output of hexdump?

  - by ??????? ???????????

  Printing these characters in the "Canonical" format gives the output that I expect, while the default format throws me off. $ echo " " |hexdump # Reversed? 0000000 0a20 0000002 $ echo -n " " |hexdump # Ok, fair enough. 0000000 0020 $ echo " " |hexdump -C # Canonical 00000000 20 0a | .| 00000002 With a different string, such as "123" the output is even more confusing: $ echo "123" |hexdump 0000000 3231 0a33 0000004 The output here does not seem "reversed", but rather shuffled. Would anyone care to explain (briefly) what is going on here?

• Why does 1080p through a VGA cable fit my HDTV but is oversized when through an HDMI cable?

  - by GraemeF

  I have put together a new PC with a XFX GeForce GTX 260 graphics card and have it connected to my HDTV. First, I used an old VGA cable with a DVI to VGA adapter and plugged it in to my HDTV's VGA port. Running at 1920x1080 it fit the screen perfectly. Now, to avoid running another cable across the room, I have connected it with a DVI to HDMI cable to my TV's HDMI port, and the desktop at 1920x1080 is cropped by the edge of the screen. I have "fixed" the cropping by using NVIDIA's "Adjust desktop size and position" tool, which created a screen resolution of 1814x1022 to fit the screen, but this is no longer the TV's native resolution and confuses some software (e.g. WoW). Why does VGA work as expected, but HDMI is scaled up? Can it be avoided?

• Is there a device that allows watching international internet TV on my LCD TV?

  - by djangofan

  Is there a Home Theatre device that will allow watching international interent TV on my LDC TV? I saw one once but I am not able to find it. I am NOT talking about a Slingbox here. Something like WWitv.com or TV.exe , but made as a set-top box for the livingroom.

• Surfing the internet while downloading becomes painful

  - by Mehper C. Palavuzlar

  When I try to surf the internet while downloading files (http based, torrent etc.), it becomes painful to open web pages since download traffic is mostly allocated for downloads. Is there a program that can manage this process so that when I surf the weight will be given to internet browser, and when the browser is idle, the weight will be on the download side? I'm using Firefox 3.6.2 on Win7, so any good Firefox addons or Windows based freewares are acceptable.

• Is there any way to make Mac OS X Spotlight only index the file names and not the contents?

  - by aalaap

  I do understand that the point of Spotlight is to look inside files, but it also returns file name matches, and that's what I need most of the time. Besides, Spotlight is running so absurdly slow on my system (Snow Leopard on the iMac '08), it's just unusable. I downloaded Canary and Spotlight wasn't able to find the app file for 15 minutes. It was already in the download stack, but as far as Spotlight goes, the file doesn't exist. Hence, I would like to know of a way to make Spotlight only index the file names, which would perhaps make it a bit faster. I'm looking at mimicking the behaviour of Windows applications such as AvaFind or Search Everything Edit: Let me highlight the fact that I am looking for an AvaFind or Search Everything replacement for Mac OS X. Go try one of these on a Windows machine and you'll understand my disappointment with Spotlight or any other popular search tools in OS X.

• Compressing with RAR vs ZIP

  - by FerranB

  A lot of people are compressing files with RAR, sending compressed files with RAR and so on. ZIP is more standard and works on all platforms. Windows users have ZIP included and linux users have no trouble with that file format. The tests I did sometime ago showed me that RAR compress better (some KyloBytes, no more) but not enough to use a non-free software when ZIP works on almost all the computers for free. Why do some people use RAR rather than ZIP for compressing?

• DNA and Quantum computing

  - by Jacques

  I recently(A couple of weeks ago) read an article about the future of processing and how quantum-processors and DNA-processors(DNA-computing) are the future competitors of computing since both will completely outperform the computers of this era. In terms of processing speeds, what do we expect from these two different processing techniques ? Personally I believe that DNA-processing will be a major step towards AI. For labs and office work I think quantum-processing which will be more logical. I'm quite excited that i'm still so young - to see what the future of technology holds! Then again my parents will soon find out what the after-life holds... just as bloody exciting, if not more..

• Can't connect to Windows Server 2008 shared folders via VPN connection

  - by Pearl

  I set up an VPN connection on my 2008 server using RRAS. The VPN seems to work fine. I can connect from outside the network. I am also able to establish a remote access connection via the VPN-IP. However, I can't access my shared folders. After connecting to the VPN I can ping the server, but it is not shown in my networks. using \ip or \server-name doesn't work either, cannot be found. I checked ipconfig and this is what I found regarding the VPN: DNS-Suffix: Description: test Physical Adress: DHCP activated: No Auto-Config: Yes IPv4-Adress: 192.168.2.114 Sub: 255.255.255.255 Standard-gateway: DNS-Server: 192.168.0.1 NetBIOS: activated To clarify my IP-situation: server is connected to router with 192.168.0.x, the test-client is in an external network connected to a router with 192.168.1.x, server-client connection is using static ips with 192.168.2.x Can anyone help me with this one? The VPN should be ok since I am able to establish remote access.

• How to get an ARM CPU clock speed in Linux?

  - by MiKy

  I have an ARM-based embedded machine based on S3C2416 board. According to the specifications I have available there should be a 533 MHz ARM9 (ARM926EJ-S according to /proc/cpuinfo), however the software running on it "feels" slow, compared to the same software on my Android phone with a 528MHz ARM CPU. /proc/cpuinfo tells me that BogoMIPS is 266.24. I know that I should not trust BogoMIPS regarding performance ("Bogo" = bogus), however I would like to get a measurement on the actual CPU speed. On x86, I could use the rdtsc instruction to get the time stamp counter, wait a second (sleep(1)), read the counter again to get an approximation on the CPU speed, and according to my experience, this value was close enough to the real CPU speed. How can I find the actual CPU speed of given ARM processor? Update I found this simple Pi calculator, which I compiled both for my Android phone and the ARM board. The results are as follows: S3C2416 # cat /proc/cpuinfo Processor : ARM926EJ-S rev 5 (v5l) BogoMIPS : 266.24 Features : swp half fastmult edsp java ... #./pi_arm 10000 Calculation of PI using FFT and AGM, ver. LG1.1.2-MP1.5.2a.memsave ... 8.50 sec. (real time) Android # cat /proc/cpuinfo Processor : ARMv6-compatible processor rev 2 (v6l) BogoMIPS : 527.56 Features : swp half thumb fastmult edsp java # ./pi_android 10000 Calculation of PI using FFT and AGM, ver. LG1.1.2-MP1.5.2a.memsave ... 5.95 sec. (real time) So it seems that the ARM926EJ-S is slower than my Android phone, but not twice slower as I would expect by the BogoMIPS figures. I am still unsure about the clock speed of the ARM9 CPU.

• Excel data into PowerPoint slides

  - by nqw1

  I have already found some helpful sites but I'm still unable to do what I want. My Excel file contains few columns and multiple rows. All the data from one row would be in one slide but data from different cells in that one row should go to a specific elements in PP slide. At first, is it possible to export data from an Excel cell into a specific text box in PP? For example, I would like to have all data from the first column of each row go to a Text box 1. Let's say I have 100 rows so I would have 100 slides and each slide would have Text bow 1 with correct data. Text box of slide 66 would have data from the first column of row 66. Then all data from the second column of each row would go to a text bow 2 and so on. I tried to do some macros with bad success. I also tried to use Word outlines and export them into PP (New slide - Slides from Outline) but there seems to be a bug since I got 250 pages of gibberish. I had only two paragraphs and both had one word. First paragraph used Heading 1 style and second paragraph used Normal style. Sites what I have found, use VB and/or some other programming language to create slides from Excel sheets. I have tried to add those VB codes into my macros but none of them hasn't worked so far. Probably I just don't know how to use them correctly :) Here's some helpful sites: VBA: Create PowerPoint Slide for Each Row in Excel Workbook Creating a Presentation Report Based on Data Question in Stackoverflow I use Office 2011 on Mac. Any help would be appreciated!

• Python version priority in OSX/UNIX PATH environment variable

  - by mindthief

  Hi all, I want my system to use /usr/bin/python, but it's currently using /opt/local/bin/python, which points to /usr/bin/python2.6. I tried modifying the PATH variable in my .bashrc as PATH=~/bin:$PATH ...and then set a symbolic link in ~/bin to point to /usr/bin/python. i.e. ~/bin/python --> /usr/bin/python I figured this might prioritize this symlink over the /opt/local version if it came before the other one in the PATH variable, but when I opened a new shell I still found python pointing to /opt/local/bin. Any advice on a good way to get the system to use /usr/bin/python? Also, I usually use ipython as opposed to python directly. I'm assuming that if the system starts to use the correct version of python then ipython would also use that version? If not, how could I also get ipython to use the correct version? Thanks!

• Installing FIREFOX with extensions/addons manually? (not really auto install)

  - by BrownChiLD

  I've been reading around with regards to creating firefox installers, bundling it w/ addons, using scripts, and CLI lines and a whole bunch of stuffs ... but it seems that going through this route is just too complicated and time consuming.. Since i don't mind a bit of manually copying files and stuff, I was planning to do the following: on my test machine, 1) install firefox on a machine AND configure it the way i want it 2) install addons AND set the configurations for it 3) set advanced configurations for firefox (about:config) Then once i'm all set, I just simply copy the contents of the firefox/profiles folder (for this particular tests it's ....\AppData\Local\Mozilla\Firefox\Profiles\6m0mef0s.default for deployment, all i have to do is: 1) Install the same version (offline installer) of the Firefox i used.. 2) overwrite the contents of the new profiles folder (randomly named by Firefox installer as usual) .. This should set all my configs and addons right? or what other folders do i have to backup and copy manually into the new profiles folder? I don't think i need to tinker w/ any registries right? anyway, if this works, though it's a bit manual, it's a whole lot simplier, and straight forward than fiddling w/ Installers and Packages etc.. PS I do this a lot w/ other simple (and some complex) software that i use and they seem to work fine for years.. i'm just not sure with firefox and how it's structured..

• Determine the time difference between two linux servers

  - by Paul

  I am troubleshooting a latency network issue on a network. It is probably a nic or cabling issue, but while I was going through the process of figuring it out, I was looking at the timings of a ping packet leaving a network card and arriving at another server. Both linux. So I have tcpdump running on both, and I issue a ping from one to the other, and back again, and looking at the timing differences might have shed light on where the latency is coming from. It is an academic exercise now, as I need to eliminate some more fundamental causes, but I was curious as to how this could be achieved. Given that ntpd is installed and running on two servers, how can I confirm the current time discrepency between the two servers, to whatever level of accuracy is possible - given that we are talking about latency on a local lan, which is ideally a millisecond or so. NTP itself is accurate to a couple of ms under good conditions, and as both servers are in the same environment, they should (presumably) achieve a similar level of accuracy, and so should have a time discrepency between them of a only few ms - but how can I check this?

• Why does Adobe Acrobat Reader require a restart on update?

  - by White Phoenix

  Why does Adobe Acrobat Reader require a restart when you update it? It's a piece of software that reads PDFs. Just what else is it installing/updating that requires a total OS reboot to "complete" the installation? A bit of Googling indicates that it's to allow the OS to install the Adobe "Speed Launcher" - is this it or are there other components that are more tightly into the OS that it must absolutely have to have closed so that it can update them?

• How does too many requests make a server crash?

  - by eSKay

  I am wondering why websites crash at all. If a server has too many requests, it might queue up the request in its waiting lists and serve it when all the earlier requests have been served. That means that the request for the website will be taken care of, although it may take some more time than expected. Then, how do websites crash due to server overload?

• Chrome shows "The site's security certificate is not trusted" error

  - by Emerald214

  From this morning I get this error whenever I access Google Docs and some websites. My system datetime is correct and I checked "Automatically from the Internet". My BIOS is OK. I cleared everything (cache, cookie, private data) in Chrome and restarted OS but nothing changes. How to fix it? Firefox works but Chrome has that problem. The site's security certificate is not trusted! You attempted to reach docs.google.com, but the server presented a certificate issued by an entity that is not trusted by your computer's operating system. This may mean that the server has generated its own security credentials, which Google Chrome cannot rely on for identity information, or an attacker may be trying to intercept your communications. You cannot proceed because the website operator has requested heightened security for this domain.

• finding IP address using Linux command prompt

  I'm looking for a way to get my IP address using the command prompt in Linux. I know when you type "ifconfig" you can get your local IP address (i.e. 192.168.0.103), but I'm looking for my IP address that I get from my ISP. How can I get this from Linux without having to visit some website?

• Fastest way to restore Windows 7's original MBR?

  - by Shiki

  I have removed GRUB's partition, and I wanted to restore the original Windows boot part. WinToFlash failed again to make my pendrive bootable, thus I'm in a bit of a trouble now. I looked all around, but I couldn't find any easy way to do this. What is the easiest and fastest way to restore the MBR? (I've got no Windows 7 DVD with me right now. And fetching the DVD is not really fast with a slower connection.)

• Enable/Disable a network adapter with a keyboard shortcut

  - by Carlos

  I started out trying to use a shortcut to display the Local Area Connection Status window on my desktop by creating a shortcut and assigning it Ctrl+, (comma). Windows didn't like that, so it added Alt, which ended up being Ctrl+Alt++,. Since I couldn't figure out a way to eliminate Alt as part of the shortcut keys, I am now trying a different strategy and it's not working. My latest attempt is to use AutoHotkey with the following command: ^,::Run, explorer ::{BA126ADB-2166-11D1-B1D0-00805FC1270E} Which is what the shortcut target number is, but it won't open the window.

• How to read unix usage

  - by sixtyfootersdude

  I did some searching but I cannot find documentation on how unix usage works. I know somethings (mostly through trial and error) but for example how do I know that: /usr/bin/ls [-aAbcCdeEfFghHilLmnopqrRstuvVx1@] [file]... Means that you can include more than one option. Ie: ls -la Can someone point me to some documentation on what the usage syntax is.
