Working Mac OS X Tiger is definitely the right source for strength clients and method directors such as you who are looking to tweak Tiger, the recent liberate of Mac OS X, to run quicker, greater, or simply in a different way. for those who areready to dig deep into your Mac, this booklet expertly publications you to the middle of Mac OS X. It is helping you know the interior workings of the working method so that you can understand how to get the main out of it.
This is often an outstanding ebook! It explains many stuff i have spotted yet did not understand good in FreeBSD and Linux. The authors are very proficient at speaking, a unprecedented reward bearing on tech booklet and on-line document authors (generally, such works so uninteresting, they might purely serve (too usually) as ambiguous reference material).
Mark Collins, Linux online game Programming (Prima, 2001)
The major challenge with examining desktop books which are six years outdated is that, good, they're six years previous. this isn't a massive challenge within the home windows global; as we've seen, occasionally the most up-tp-date home windows know-how will remain round much longer than the provider contracts mandate. That, even if, is sort of by no means the case with Linux, the place an important pool of builders pretty well guarantees that issues will develop and alter on a per month, if no longer day-by-day, foundation. nonetheless, the fundamentals of the mandatory wisdom to get lower than the hood and tinker with Linux will carry precise, so it is not like there is totally not anything to realize from a e-book like this if you are a complete newb. (Sorry, I despise that spelling, but when i take advantage of the right kind one, Amazon filters it for being one letter off from a undeniable slang time period they do not appear to like. )
I am, in reality, that newb. Having eventually thrown Microsoft over for reliable in each point of my lifestyles i will (I nonetheless maintain a home windows field round for video games, and i've to exploit it at work), all these database and video game initiatives i used to be engaged on must be Linux initiatives now. So i began with what i'll get on the library, Collins' six-year-old treatise on Linux video game programming. First, enable me say that in case you are searching for hands-on instructional stuff, this isn't the ebook for you. Collins is extra drawn to getting you to appreciate the concepts--why you must do whatever, instead of what it truly is you need to do. whereas this is often evidently an outstanding factor and results in programmers who comprehend extra of what they're on approximately, it is most likely worthy a caveat emptor for the folk who're simply trying to find shortcuts, or solutions to a particular challenge. the second one factor to be stated, then, is that online game layout itself is the main transportable a part of any online game undertaking. whereas Collins does delve into a few issues which are extra appropriate to Linux improvement than the other type (an complete bankruptcy, for instance, is dedicated to the OpenSource debate), the various particular instruments Collins talks approximately, and the entire high-level recommendations, are appropriate to online game designers who software for any platform. therefore, i'll move methods right here; criticize the publication for probably not being approximately Linux particularly, or compliment it for being universal?
The challenge is, i will not do one or the opposite. How helpful you will find it's going to most likely rely on how a lot analyzing you may have already performed on designing video games and constructing video games with C++. If you will have performed plenty, you'll get the main worthy out of the chapters on SDL and openGL/openAL; differently, learn the whole lot. ***
Webmin & VirtualminThis strong, open resource software program is likely one of the top keep an eye on panel i have come acrosss that will help you deal with your Linux servers through the web-browser. it's extra robust and versatile in comparison to Cpanel & Plesk, and it consumes much less assets. this means that, extra RAM and CPU cycles can be found in your purposes.

In such cases, for performance reasons, the wait list associated with the object and the state of the pthread are not always updated to accurately reflect the pthread's true condition while it is waiting in the kernel. This feature ensures that wait list and state information is accurate for pthreads waiting on process private pthread objects. 0, an extension of the pthread library function pthread_getthrds_np() was introduced to support signal handler contexts on the stack. 1, the pthread library is enhanced with a new API to support a similar function.
Previously, the getrusage() system call was used, but this facilitates the entire process scope resource usage only, therefore it cannot be used to query the resource usage per thread. Because it is also necessary to monitor threaded applications, the DPCL tool will call the pthread_getrusage_np() library call. This pthread library call supports both 32-bit and 64-bit applications and 32-bit and 64-bit kernels. In the instance where old binaries make use of this pthread library call, it will be necessary to recompile the source code.
