After some time into web application development during my undergraduate study, I had wondered about the effect of modifying the underlying DB tables when a query result set over the DB tables are being iterated by a PHP script making an HTML table. Well, I believe that the result set is contained in its own memory and is detached from the underlying DB tables so the iteration will not be affected by any change to the underlying DB. How about the use of a cursor or a similar mechanism in iterating the result set? Well, I believe that the cursor operates on the result set memory instead of on the underlying DB. Well, those assumptions can be wrong and the DB can choose to employ locking. If locking is employed, how does it affect the other writers or readers? I think the sure way to answer the posed questions is by conducting some tests to see the behavior of the DB when using its API. Below is the result of conducting some tests on Sqlite3 to answer the above questions when I was working on Service Publishing AP.
After successfully getting an Internet connection using Prolink PHS100 here, my brother needs to use Huawei E160 with that laptop. It turned out that for Huawei, /dev/ttyUSB0 should be used. The steps are just as follows:
1. Fire `sudo aptitude install wvdial' if you don't have it installed yet.
I've found a way to use proposed in "ssh brute force" post method to auth users on some kind of services, server may provide, but where software may not support authentication at all.
Opinions on this auth for tinyproxy are welcome.
My first experience of dealing with GSM modem was for an SMS gateway using Huawei E220 in which only a SIM card without a broadband Internet connection was used. I had tried several times in those days to connect to the Internet using SIM cards with a broadband Internet connection to no avail because I always got stuck when executing `sudo wvdial' in which fancy ASCII characters were displayed on the screen. I didn't pursue the solution because a GSM modem was still expensive and the 3G signal was weak at my place. But, this time I really needed to connect to the Internet using Prolink PHS100 GSM modem.
Having a programming project for a service publishing wireless access point running OpenWRT Kamikaze 8.09.1 in which I decide to use sqlite3 as the data backend, my first attempt in cross-compiling and running the service inquiry handler daemon that was fully tested on my laptop was greeted with a hang.
About some weeks ago I got the chance to fiddle with Android (http://www.android.com) that is used in mobile service discovery research in Mobile Communication System Engineering Lab (http://ds.informatik.rwth-aachen.de/teaching/ws0910/mcse/). The assignment was to create a simple ToDo list (http://github.com/eus/android_todo). But, it turned out that programming Android's ListActivity to highlight a ToDo item was not that simple.
Some weeks ago I had the chance to fiddle with OpenWRT (http://openwrt.org) on ASUS WL-500W router because I got an assignment to extend Screamer (http://github.com/eus/screamer/) further: assignment 4 (http://github.com/eus/screamer/blob/master/doc/assignment4/assignment4.txt). The OpenWRT wiki was sufficient to get everything up and running (http://nuwiki.openwrt.org/oldwiki/openwrtdocs/hardware/asus/wl500w), but the network configuration was not right for the task at hand that required that traffic from and to each LAN port and the WLAN interface has to be filtered.
I'm back too. Back to my native places, native laguage etc. I've got some internet access and will share something (hopefully).
Want to start publication also in russian laguage. Let's see what will happen.
So, итак, я снова на кернелтрап.орг. Вернулся на родину, добыл немного интернета, и думаю начать публиковать информацию также на русском языке. Посмотрим к чему это приведёт.
Now that I'd got another chance to develop a C application, whenever I crafted a header file, I always wondered whether the header file needed to include another header file such as stdio.h when there was a function prototype in my header file that spelled `FILE *'.
Kernel podcast should be included in the news area
If no one have time i can do the postings to this site , i also i'm editor on firebirdnews.org
The best digital cameras take fantastic pictures, and pictures are memories. The best digital cameras record so many memories that will remain treasures for generations. The best digital cameras have improved so much that even the pros are using these great machines.
I came across this code, which was supposed to demonstrate a Prolog program that couldn't be written in Mercury. I couldn't help but rewrite that as:
rank(Xs,Rs) :- pairs_keys_values(Decorated,Xs,Rs), keysort(Decorated,Sorted), numerate(Sorted,1). numerate(,_). numerate([_-N|Rest],N) :- N1 is N + 1, numerate(Rest,N1).
...This computes the rank order of a list of elements. For example
[3,2,4,1], since 40 is the third largest element, etc.
"The most exciting (well, for me personally - my life is apparently too boring for words) was how we had some stack overflows that totally corrupted some basic thread data structures. That's exciting because we haven't had those in a long time.
