  • PHP vs Batch file for mysql cronjob?

    - by mysqllearner
    Hi, My server details: OS: Windows Server 2003 IIS6 Plesk 8.xx installed (currently using Plesk to set the cronjob) I need your advice. I have 2 methods: Method 1: Using php + mysqldump, create databases backup files into gzip, and then send email with attachment (each databases has around about 25mb) Method 2: Using batch + mysqldump, create databases backup files into gzip, and then send email with attachment (same, each databases has around about 25mb) My questions: Whats the difference of using php file and batch file for cronjob? Which method is better in term of backup speed and send email, and (maybe)safety (e.g., lesser file corrupt occurance)? If i set the cronjob hourly, will it effect my web performances? I mean, lets say my website has 100++ users online now, and each user making transaction to MySQL, when I perform backup at my web peak hour, will it decrease the performances, like the loading speed, prone to errors etc?? (sorry for my bad english) P.S: If you need my php and batch file code, please ask me to post it here. I didnt post it now is because, its very simple and standard code.

  • How to compare old CPU to new CPU?

    - by Lasse V. Karlsen
    I hope this question doesn't get closed at once :) I have an old laptop, a Compaq NC4200, which is going its final laps around the track these days. Battery is dead, and everything kinda runs slow. It also has only 1GB of memory, and even though I don't know if it can take more, I probably wouldn't be able to get hold of any that matches without having to special order it. The size, however, has been ideal for my usage pattern, so I'm looking to replace it with a similarly sized laptop, at least in the same size category. However, it's been a while since I tried keeping track of CPUs, so I have a question. The old laptop has a Intel Pentium M 760 1.86GHz processor. One laptop I found online has a Intel Pentium SU4100 1.3GHz dual-core. This type of processor seems to be quite common in the price and size-range I've been looking. What kind of relative performance boost could I expect from the old one to the new one? I am not expecting a "about 7.45x speed", but some indication would be nice. For instance, dual-core tells me it might be akin to 2.6GHz, but I assume I can't simply compare 1.86GHz to 2.6GHz and expect the new one to run about 1.4x as fast, I expect more these days. Or is that unrealistic for this kind of processor? Do I need to up my price range and go for a 2+ GHz processor?

  • Macbook Pro 2.66 GHz vs. 2.8 GHz

    - by nevan
    Is there much advantage in getting the higher end Macbook Pro compared to the mid-range one? The differences between the two are: 2.66 GHz vs. 2.8 GHz 256 MB graphics memory vs. 512 MB 3 MB L2 cache vs. 6 MB 320 GB hard drive vs. 500 GB $2000 vs. $2300 I've looked around, but I can't find any direct comparisons for the two machines. I'd be using the machine for development. I generally use a computer for 3 years. I don't really play games, but do use Photoshop regularly. I've heard that once Snow Leopard arrives, the graphics chip will be used to boost the main processor, so I was wondering if getting the one with more graphics memory would be an advantage?

  • Pentium 4 Willamette vs. Faster Celeron Northwood [closed]

    - by Synetech inc.
    Which is the preferable of the following two processors? Intel® Pentium® 4 Processor 1.70 GHz, 256K Cache, 400 MHz FSB Willamette Intel® Celeron® Processor 2.40 GHz, 128K Cache, 400 MHz FSB Northwood Details: A few months ago my motherboard died, so I bought a used computer that had a 2.4GHz Celeron. My old system had a 1.7GHz Pentium 4, so now I’m trying to decide which CPU to use. Obviously a P4 is preferable over a Celeron, but the Celeron is (significantly?) faster than the P4. I’m wondering if the faster Celeron might be better for certain tasks (ie, stronger but dumber is better at some things than smarter but weaker). I tried Googling for some reviews and comparisons for graphs to get a clear depiction of which is better overall, but found nothing that helped. (I did manage to find one page that indicates (apparently by poll, not benchmark) that the Celeron is better.) So which CPU should I use? Does anyone know of some graphs that I can use to compare the two? The system is a general-purpose machine for word-processing, Internet, and casual games (not Crysis, but not Solitaire either). It will be running Windows XP. The board is a 478 with 400MHz FSB.

  • Color Printer: Laser vs Inkjet

    - by Mike
    I am about to buy a color printer. I had a B&W Laserjet printer in the past but since then I've used inkjets for decades. I need a printer that can deliver high quality as these photo inkjet printers, but I'm tired of paying for ink that costs $9,000 per gallon (1 gallon = 3.785 liters = 300 cartridges = $9,000). So, I was thinking about buying a color laser printer, but I'm not sure these printers can deliver the same quality and are worth the investment in terms of toner consumption. I remembered that my old Laserjet printer was able to print 1100 pages per toner cartridge. The inkjet printers I have can print 500 pages per cartridge. Price by price, 2 inkjet cartridges have more or less the same cost as one toner cartridge and in theory prints almost the same. I am not sure if this is true for color lasers. What can you guys tell me about quality, toner cost and cost per page for laser or inkjet printer? Is it worth the change? (Keep in mind that an inkjet printer costs $50 and a laser printer costs $200.) Thanks.

  • Difference between resin and resin pro

    - by riteshmnayak
    I planning to deploy resin for a project that I am working on but cannot figure out the version of resin I must use. The downloads page lists two products, Resin and Resin Pro with dev, stable snapshots. What is the difference between the pro version and the plain version? Is pro a paid version or something?

  • FTP v/s SFTP v/s FTPS

    - by susmits
    We're setting up a web server at our workspace. In conjunction, we're planning to install an FTP server, however I'm stuck at what protocol to employ -- FTP, SFTP or FTPS. I googled around, trying to see what protocol offers what, coming across articles like this, but I can't make up my mind. Only simple, once-in-a-while file transfer is desired; however, security is a concern since the file server is intended to be accessible from the internet. What protocol is the most apt for my use, and why?

  • Identify differences between MP3 files

    - by Thingomy
    I have 2 old similar directory trees with MP3 files in them. I am happily using tools like diff and Rsync to identify and merge the files that are only present on one side, or are identical, I'm left with a bunch of files that are bitwise different. On running diff over a pair actually different files, (with -a tag to force text analysis) it produces incomprehensible gibberish. I have listened to files from both sides, and they both seem to play fine (but at nearly 10 minutes per song, when listening to them twice each, I haven't done many) I suspect the differences are due to some player in the past "enhancing" my collection by messing about with ID3 tags, but I can't be certain. Even if I identify differences in ID3 tags, I would like to confirm that no cosmic ray or file copy error issues have damaged any of the files. One method that occurs to be is finding the byte locations of the differences, and ignoring all changes in the first ~10kb of each file, but I don't know how to do this. I have on the order of a hundred or so files that differ across the directory tree. I found How to compare mp3, flac audio data in a file, ignoring header data (ID3 tag) etc.? -- but I can't run alldup due to being Linux only, and from the sounds of it, it would only partially solve my issues anyway.

  • Could it be sane to use Windows Server 2012 as desktop

    - by nCdy
    what about using it on desktop? I've got enough strong PC with intel core i7 and 8GB Ram so what should I think about: why not? Were looking about major differences compared to windows 8, found less. for example new file system - can it affect me? In my usual day I need development instruments alike visual studio, virtualization tools, and some games So far I can't find something that must stop me, everything I need can work (seems like) there. Tell me why I must not do it or if that is sane to do.

  • vimdiff: Jump to next difference inside line?

    - by sleske
    vimdiff is very handy for comparing files. However, I often use it on files with long lines and relatively few differences inside the lines. vimdiff will correctly highlight differences inside a line (whole line pink, differing characters red). In these cases, it would be nice to be able to jump to the next difference inside the line. You can jump to the "next difference" (]c), but this will jump to the next line with a difference. Is there a way to go to the next different character inside the current line?

  • SCSI vs SATA? Is SCSI "actually" better?

    - by earlz
    Well, I was talking with a guy about servers the other day. I was a bit shocked whenever I asked him if there was any significant difference between SCSI and SATA and why he always uses SCSI. (note, I'm not sure if by SCSI he meant SAS) He told me that SCSI is always faster and that the drives are always more reliable.. I mean, this seems like a bold statement. He told me something about how SCSI will always be faster than SATA because the OS sends the SCSI (controller?) a request to get a file and it will build the file inside of the SCSI controller, instead of searching all over the disk.. which I do not understand how that would work, so I figure it is BS. SAS and SATA currently have equivalent data rate speeds.. Is there any true backing for his reasoning that SCSI is always faster and more reliable than SATA?

  • Best way to compare (diff) a full directory structure?

    - by Adam Matan
    Hi, What's the best way to compare directory structures? I have a backup utility which uses rsync. I want to tell the exact differences (in terms of file sizes and last-changed dates) between the source and the backup. Something like: Local file Remote file Compare /home/udi/1.txt (date)(size) /home/udi/1.txt (date)(size) EQUAL /home/udi/2.txt (date)(size) /home/udi/2.txt (date)(size) DIFFERENT Of course, the tool can be ready-made or an idea for a python script. Many thanks! Udi

  • Is there a program that compares image files and reports if they are exactly the same pixel-wise?

    - by Nathaniel Drake
    I'm making a regression testing suite for some rendering software. I need to be able to load an image file (PNG or TGA, ideally) and compare the pixel values to a standard approved image. I'd like it to be command line driven too, so I can make a batch file to run all the tests. All the compare utilities I have found so far either show differences (I just need it to fail if they are different) or compare all the bytes, meaning that meta-data will trigger a fail. Anyone got any suggestions? I am not a coder, and can only barely cobble a batch script together. Thanks for any suggestions.

  • What can be done in Windows 7 that can't be done in Windows XP?

    - by emddudley
    In Jeff Atwood's latest blog entry on Windows 7 he talks about getting people to move off Windows XP. What, specifically, can be done in Windows 7 that cannot be done in Windows XP? I'm not looking for usability or GUI improvements, unless they happen to significantly reduce the time that it takes to perform tasks that were previously prohibitively time consuming.
