  • Is there Linux Live USB that works with Snow Leopard macbook pro from 2010 april

    - by rofrol
    Hello, I was searching for a long time a Linux Live USB that I can boot my macbook pro from. Is there such distro so I can install it on Snow Leopard or Windows 7? UPDATE I've found this: "isohybrid" CD images (..) are special in that as well as the normal CD-based ISO9660 filesystem they also contain a valid-looking DOS-style partition table. Thus, if you simply copy one of these images raw to a USB stick a normal PC BIOS will boot the image directly. (...) Finally: I'd like to add support into xorriso for creating the nasty HFS hybrid images that are needed for booting Macs. The code that does this in cdrkit is probably some of the worst that I've ever worked with, and I'd like to get away from it. If only Apple hadn't stupidly built their proprietary platform around this shit and had used open standards instead Source

  • In django, how can I include some default records in my models.py?

    - by kdt
    If I have a models.py like class WidgetType(models.Model): name = models.CharField(max_length=200) class Widget(models.Model): typeid = models.ForeignKey(WidgetType) data = models.CharField(max_length=200) How can I build in a set of built in constant values for WidgetType when I know I'm only going to have a certain few types of widget? Clearly I could fire up my admin interface and add them by hand, but I'd like to simplify configuration by having it built into the python.

  • Is it safe to set MySQL isolation to "Read Uncommitted" (dirty reads) for typical Web usage? Even with replication?

    - by Continuation
    I'm working on a website with typical CRUD web usage pattern: similar to blogs or forums where users create/update contents and other users read the content. Seems like it's OK to set the database's isolation level to "Read Uncommitted" (dirty reads) in this case. My understanding of the general drawback of "Read Uncommitted" is that a reader may read uncommitted data that will later be rollbacked. In a CRUD blog/forum usage pattern, will there ever be any rollback? And even if there is, is there any major problem with reading uncommitted data? Right now I'm not using any replication, but in the future if I want to use replication (row-based, not statement-based) will a "Read Uncommitted" isolation level prevent me from doing so? What do you think? Has anyone tried using "Read Uncommitted" on their RDBMS?

  • InnoDb Overhead?

    - by Rimary
    I just converted several large tables from MyISAM to InnoDB. When I view the tables in phpMyAdmin, they are showing a significant amount of overhead (One table has 6.8GB). Optimizing the tables (which isn't a supported command on InnoDB) has no affect like it does on MyISAM. Is this a result of InnoDB having the ever growing data file that never returns space even after deletes? If that's the case, I've never seen overhead like this before from other InnoDB tables. Is there a way to clean this up? Edit: Here are the things I've tried (with no success): Optimize Table Reorder table by primary key Defragment table

  • replacing a path with sed

    - by compie
    How can I use sed to replace this line char * path_list_[1] = { "/some/random/path" }; with this line char * path_list_[2] = { "lib/foo", "lib/bar" }; in a file named source.c Notes: * The path is really random. * Your solution should only change this line in source.c * I'm only interested in a sed oneliner. You can use this Python regex as a starting point: text = re.sub('static const char \* path_list_\[1\] = \{ "[^"]*" \};', 'static const char * path_list_[2] = { "lib/sun", "lib/matlab" };', text)

  • How to sleep computer via batch file?

    - by Saebin
    So I want to make a batch file that will sleep my computer after a period of time. The closest thing I have found is placing it in standby, but seems to work differently then the sleep button on my keyboard (longer bootup, doesn't wake on mouse click). Any ideas? Would it be easier in python or c#?

  • Lost Firefox and Notepad++ icon

    - by Shiki
    Okay the deal is simple. I lost the icons and see that white icon instead of them in the taskbar which is really annoying. Tried reinstalling Firefox, no use. (Tried checking the firefox icon in the app folder (program files), but same situation there, no icon). OS: Windows 7 x64 up-to-date, every update installed (Maybe related: I installed my PC with a wrong account name. Renamed it. That rename caused much headache since Windows messes with my user folder, bla bla. Now I made a new user, called "S" and I'm using this ever since that incident.)

    Lately I have been having my eye on evented I/O to tackle some of my web application problems. I have been looking at things as Python's Twisted, Ruby's Eventmachine, and Node.js. Are there any other alternatives to these three, maybe in other languages as PHP ?

  • Recover deleted files on windows 2008 file server

    - by aniga
    We have recently been hit by a weird virus which made all files and folders a system files/folders and also it hid all files and folders par some weird ones it created including: ..exe porn.exe secret.exe password.exe etc We have managed to restore the files with attrib command to unhide and unmark them as system files however we have noticed that we are missing some 4 to 5 folders of which (based on my luck) 2 of them are the two most important client we have. I am not sure if these files were deleted by the worm/virus or by my colleagues who are not owning up to them but the files are now gone. Worst of all, we do not have any backup what so ever (Yes I know, we should not have done that but it is a lesson learned and since last night we have created two forms of backup systems one to external device and one on the cloud, but I doubt any of that will help us now) We have 1 Windows 2008 File server and 4 client computers based on Windows 2007. I would be grateful if anyone can help us on how we can recover from this disaster which could potentially put us out of business.

  • Does Ruby have a special stack for returning a value?

    - by prosseek
    The following Ruby code def a(b,c) b+c end is the same as follows with Python def a(b,c): return b+c It looks like that ruby has the special stack that stores the final evaluation result and returns the value when a function is called. If so, what's the name of the stack, and how can I get that stack? If not, how does the Ruby code work without returning something?

  • Is there a word processor similar to MS Word which saves files as readable txt files?

    - by zenbomb
    I'm writing a paper together with my supervisor and would like to have a more sophisticated version control than *_291112_NEW_NEW_revised1.doc files. My supervisor is a non-computer person will never ever use LaTeX or git and loves MS Word. I'm therefore looking for an alternative to Word (I need commenting on text passages!) which stores the files as clean text (Markup for formating is fine), so I'm able to put them under version control on my side. I'm aware that git can also handle binary files, but I'd prefer the cleaner way of looking at the contents directly. If there's a way to automatically extract the text from word files, I'm fine with that too for now.

  • Is putting swapfile & temp folder in ramdisk a good idea in Windows 7 64 bit with lots of ram?

    - by Tony_Henrich
    I want my Windows to run as fast as possible. If I have 12GB ram in Windows 7 64bit, quad core cpu, and all apps fit in memory, will the swap file ever be used for anything? The question is about if its a good idea to put the swap file in a ram disk. Would a ram disk help in any way or will Windows intelligently use all the available memory for all its work? I am also thinking of putting the temp folder in a ram disk. I know ram disk is volatile memory and I don't care about its content in it if it gets lost.

  • Postgres turn on log_statement programmatically

    - by rwallace
    I want to turn on logging of all SQL statements that modify the database. I could get that on my own machine by setting the log_statement flag in the configuration file, but it needs to be enabled on the user's machine. How do you enable it from program code? (I'm using Python with psycopg2 if it matters.)

  • How is the MAC address on a computer determined?

    - by Zero Stack
    While imaging some computers today, I started to wonder... what if two LAN MAC addresses on two different computers matched?... That would cause some problems. I later came to understand that the MAC address' 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses. [ in other-words, a lot of networking devices ] How are these MAC addresses determined? Will we ever run out of them? ( I know the second question is speculation, but there are a lot of devices that require a mac addresses...) Do MAC addresses get recycled?

  • Is it preferable to use POP or IMAP to check multiple google mail accounts from one?

    - by Adam Tuttle
    I have email accounts on several domains that use Google Mail, and thus far I've only ever used POP to send and receive mail from a single inbox. This is quite functional, and as long as I remember to select the appropriate FROM address when starting a new thread, mostly works without any additional thought: messages received on account A are replied to via account A, and so on. My only complaint is the lag -- I've seen sometimes as much as a half hour between messages arriving in an inbox before being imported into my primary inbox via POP. My question is this: Google also supports IMAP. Would that be in any way preferable over POP access? Reduced lag would be nice, but not at a general speed cost, if everything I do has to check another mailbox too.

  • How can I get all my itunes files from multiple computers onto my new PC?

    - by jasondavis
    Managing my itunes files (music,video,tv shows, iphone apps) is a really hard task and I have not had much luck yet. If I had a single PC for the rest of my life with the same hard drive, it would work great but infortunately it cannot be that simple. I just build a new PC as my old hard drive crashed with all my itunes purchased songs, video, etc. So is there anyway to get itunes to recognize that I own all them and let me re-download everything? As I see it so far, it knows what I own by my itunes account login (it knows if I purchased a file or not ever) but does not seem to let you just re-download everything to a new PC or new hard drive. I realize I should of had backups but I didn't. My backup plan is a work in process and it is getting much better but that doesnt help with my situation at the moment. So I am asking for any help, ideas of how to retrieve all my previous itunes purchases?

  • Specific apache + mysql settings for a light-weight site

    - by Good Person
    I have a small website with a Joomla and a Moodle set up. It seems that both of these are very slow. The server (CentOS release 5.5 (Final)) is a virtual dedicated server with about 2GB of ram. I don't expect to ever get more than 10-15 people on at the same time (and if that is high) What settings could I change in either apache, mysql, or even the OS to increase the performance of my site? I'm not concerned about running out of resources if I get too many visitors. If you need more specific data leave a comment and I'll edit the question.

  • MVC alternatives: examples of MVA & AVC?

    - by Phillip Oldham
    I'm interested in learning about the alternative patterns to Model-View-Controller, specifically the Model-View-Adapter and Application-View-Controller patterns. Google results tend to be either a high-level overview or Java-based. Can anyone either provide, or point me to, an example of these patterns in either PHP, Python or JavaScript?

  • What happened to WinFS?

    - by Console
    The most interesting feature that was ever connected to what eventually became Vista was WinFS, a revolutionary (so it seemed, at least back then) new way of storing and accessing information on a computer. This feature was cut despite actually reaching a closed alpha/technical preview release. There was a smoke and mirrors blog post from MS about the technology living on in an upcoming SQL server release, but to me it just felt like it was axed, hard. Does anyone have any idea what happened to it? Is it killed, or just on the backburner? Was it just impossible to implement, too expensive, or did someone think of a better idea? Are there any projects (From MS or anyone else) that have similar goals?

  • Programming introduction book

    - by Avi
    Hello there, I've offered an out-of-job girl to help her study programming (with an MCSD as the ultimate goal) - and she has no progrmming knowledge.

Optimally would be for the .Net 4.0 MS enviornment (C#,Visual Basic) but other alternaitves (Jave, Python etc.) are OK.
