Recently I have been working on some shell scripts to aid in the installation of applications. One of the scripts I have been working on is a LAMP (linux, apache, mysql, and php) installer. For almost two years I ran a local WAMP server (same as LAMP but the operating system is Windows) which was installed by clicking some executable (XAMPP / VertigoServ). However, Linux shows no sympathy for lazy Windows users, and thus forces us to use a restrictive package manager or install form source. Moreover, ...
Read about images, finally got the EEE PC loaded with the necessary libraries to compile wxWidgets for GTK, and ran out of hard-drive space. That's what happens when you've already downloaded a ton of junk onto, with useless updates, etc. Spent this evening reseting it to factory defaults so I can start the process over again without all the stupid updates.
Not much to say, since I've been reading function definitions, etc. Pretty boring stuff. Getting anything to Link, however, has been an adventure.GCC has a few interesting "quirks": first, it doesn't automatically locate compiled objects in the search path. Second, it doesn't automatically handle linking of dependent object files in the correct order. The result is that you end up with hideously long link commands, and if you get your compiled units in the wrong order, ...
Welcome back to Part 8 of Programs Under the Hood. Today we're going to disassemble a BIOS interrupt to get a real-world example of what programs are structured like, and we'll see if we can convert some of it to C/C++ code. (I apologize for the large line breaks. For some reason, they just appeared.) POPPING THE HOOD-DISASSEMBLING A BIOS ROUTINE A few issues back I mentioned that the BIOS provides a lot of basic functionality in assembly-language ...
What is overselling?Simply put, overselling is when a host offers to more resources to their clients than what they physically have.I would venture to say, all hosts oversell. Overselling for the most part is a legitimate practice. Most owners of dedicated servers who specialize in web hosting receive, say, an 80 GB hard drive and 8000 GB of transfer from their data center. Lets assume one of the packages a host offers for $5 a month is 1 GB of storage and 10 GB of transfer. Physically, ...
Have you ever been in a conversation where someone blurts out something completely off topic? You say to yourself, “well, that was random.” Chances are, unless that person suffers from a mental disability, that spew of “random” verbiage was not really random.What is randomness?The Oxford English Dictionary defines random as “made, done, or happening without method or conscious decision.” More than likely, your conversation sparked some conscious relocation which resulted in the person ...
After spending about 3 hours on day 2 to get things working, Days 3 and 4 were pretty boring. I'm plowing through chapter 4, which is a summary of most of the components used in wxWidgets. I spend a LOT of my time reading through them thinking that they're just like what Delphi uses.Based on what I'm reading, everything should work fairly well. My biggest issue for my long-term goals is determining whether I should use wxGTK or wxX11 when I compile for my EEE PC. ...
