How do I delay a PHP script that writes to a text file and then reads from the same file long enough to make sure changes have been written before I attempt the read?
Hi,
I need a batch file that writes the count number to a txt file.
Next time the batch file is run, it should read the current count number from the txt file and add 1 to count and save this new value in the txt file. (nothing else is in the txt file)
When count is 5 it should start from 1 again
Example:
Count.bat runs 1 time:
count.txt has no…
I have a Java program that writes results to both a DB (SQL Server) and a spreadsheet (POI), and it would be best if neither is written to if there's an error with either.
It would be a lot worse if the spreadsheet was produced and then an error happened while saving to the DB, so I'm doing the DB-write first. Even so, I'm wondering if someone…
Hello All,
When i POST the page using the following code, the Response.write("Hey") doesn't write the content ("Hello") to the parent page
<form method="post" name="upload" enctype="multipart/form-data"
action="http://localhost:2518/Web/CrossPage.aspx?cmd=getvalue" >
<input type="file" name="filename" />
<input type="submit"…
I would like to run several commands, and capture all output to a logfile. I also want to print any errors to the screen (or optionally mail the output to someone).
Here's an example. The following command will run three commands, and will write all output (STDOUT and STDERR) into a single logfile.
{ command1 && command2 &&…
My USB flash drive is currently unusable because it somehow (quite suddenly!) became write protected. I have googled around and tried many solutions to this problem, but none of them have worked so far. Here are some of the solutions I've tried:
The drive has no tangible switch or button.
Formatting the drive won't work, even in command…
I have a SanDisk Cruser Blade USB stick that suddenly seems to be write protected. I tried running DiskPart but after I write the command "attributes disk clear readonly" it displays this:
Microsoft DiskPart version 5.1.3565

ACTIVE - Marks the current basic partition as an active boot…
Below you can see my smb.conf, pieter is my admin user read/write on the shares works good with that account. Then I have a leecher account that has been added with smbpasswd -a leecher to the smb users, it is set up so this user only has read access to the shares. This works on MegaSam and on Thumbnails but not on my other drives,…
I plugged in my external harddrive (which was formatted on my Mac into HFS+ journaled) to my Ubuntu desktop 9.04 64bit. I am not able to get the drive to mount with write capability, how do I do that? Right now all I'm getting is read access, I tried
sudo mount -t hfsplus /dev/sdf2 /media/"Portable HD"
but that still gave me…
I'm not sure what has happened, but I've all of a sudden lost write access to any of my NTFS external drives.
I installed a few games and apps from the software center, and now I can't make new folders or copy and paste files to anything that is NTFS. Everything is now read only, and I've tried so many things to fix it, but it…
I have Asus P8Z77-V LK motherboard, that ran Mint 13 (based on Ubuntu 12.04) just perfectly, but recently I've tried to install Mint 17 and noticed abysmal write performance. Write speed on SSD disk was about 1.5MB/sec, when it's supposed to be in 150-250MB/sec range. For write testing I've used dd if=/dev/zero of=/dev/sda…
I'm thinking of a situation where I would have something that creates a copy of a directory, tweaks a few files, and then does some processing on the result. This wold be done fairly often, maybe a few dozen times a day. (The exact use case is testing patch submissions; dupe the code, patch it, build/test/report/etc.)

Hi,
What I wish to achieve is - log all information about each and every visit to every page ofmy website (like ip address, browser, referring page, etc). Now this is easy to do.
What I am interested is doing this in a way so as to cause minimum overhead (runtime) in the php scripts. What is the best approach for…

fprintf() does buffered I/O, where as write() does unbuffered I/O. So once the write() completes, the data is in the file, whereas, for fprintf() it may take a while for the file to get updated to reflect the output. This results in a significant performance difference - the write works at disk speed. The following…
Ads requested through via doubleclick often get served from an ad provider network that returns javascript that in turn performs document.write to place ads in the page. The use of document.write requires that the document be open, implying that the page hasn't reached document.complete. This gets in the way of…
In last week after doing more research on subject matter, I have been wondering about what I have been neglecting all those years to understand write-caching policy, always leaving it on default setting. Write-caching policy improves writing performance and consists of write-back caching and write-cache buffer…
Hey, I'd like to write to a text file to record a set of scores. However, everytime I write to it it overwrites what was originally in the file. Please can someone tell me how to not let it overwrite what is there or how to make it start writing in an empty space. Thank you in advance.

I am connecting my Ubuntu box to a wireless readout setup over Bluetooth. I wrote a Python script to send the serial information through /dev/rfcomm0. The script connects fine and works for a few minutes, but then Python will start using 100% CPU and the messages stop flowing through.

Fun with CLOBS! If you are using Oracle, if you have to deal with text that is over 4000 bytes, you will probably find yourself dealing with CLOBs, which can go up to 4GB. They are pretty tricky, and it took me a long time to figure out these lessons learned. I hope they will help…
Setup
I have an entity-component architecture where Entities can have a set of attributes (which are pure data with no behavior) and there exist systems that run the entity logic which act on that data. Essentially, in somewhat pseudo-code:

I am seeking a means to read and write OBJ geometry files with logic that does not modify the geometry representation. i.e. read geometry, immediately write it, and a diff of the source OBJ and the one just written will be identical. Every OBJ writing utility I've…
