1024 Best.rar



Compressing 6gigs worth of folders of different music using the same 1024M dictionary size resulted in only 96% ratio of compression. 5.76 gigs instead of 6gigs.The best thing to do for compression of video is lossy compression where you use a program to convert the video. Try lowering the bit-rate to something you don't notice, or can accept the video quality of. Handbrake is a decent video tool, but there are many. VLC is capable of video compression as well using the convert option. Both programs are free to use.




1024 best.rar



Both 7-Zip and WinRAR offered multiple configuration options. I began by choosing what I thought would be optimal for each. For WinRAR, I chose RAR5, Best compression method, 1024MB dictionary, no options other than delete after compression. (Later, I would find that a 32MB setting seemed to be considered optimal for the dictionary. Newer versions of WinRAR would confusingly offer RAR (rather than RAR5) as the latest version, with RAR4 as the legacy alternative.)


The question on my mind, as I started into these additional investigations, was whether RAR5 (using the 1024MB maximum dictionary size) was actually faster than RAR (using the maximum 4096KB dictionary size) in WinRAR. I had seen at least one comment suggesting it might not be. I ran comparisons on one large WAV and on a set of DOC files. On the DOC files, RAR took 15 seconds and produced a RAR only 26% of the original size (77.4MB > 20.4MB), while RAR5 took 3 seconds to achieve the same compression. Clearly, RAR5 was better for compressing these DOCs. On the WAV, however, RAR took 0:29 to achieve 61% of original size (531MB > 326MB), while RAR5 took 1:37 to achieve 66% (348MB).


I also ran a RAR vs. RAR5 comparison for MPG. On a 539MB MPG file, RAR achieved 0:41 > 528MB (98%) while RAR5 achieved the same compression just one second faster. I re-ran the test using RAR5 with a 1024MB dictionary. That yielded 1:12 > 525MB (97%). It seemed that RAR5 with a larger dictionary might achieve slightly improved MPG compression, compared to RAR, at the cost of much slower processing.


For example: 640 divided by 480 = 1.33. You may notice this matches the number for the 4:3 aspect ratio above, meaning this screen resolution (640480) displays at 4:3 aspect ratio. As another example, a resolution of 1024576 would display as 16:9 (1.78:1).


Very interesting article.I came across it looking for an answer to a simple(?) question:How will a 1280 webpage be seen on an Ipad?The website I am designing will benefit greatly from a 1280 design instead of 1024 and the target audience is wealthy people with large monitors, but also Ipads. Ipad 2 resolution is 1024, but perhaps it will automatically scale the 1280 website instead of introducing a horrible horizontal scroll bar?I have an Ipad2 myself and a 1280 website looked perfectly fine on it, but I am not sure how or why.


Remember, the amount of clients that can be served can be multiplied by the amount of cores. In this case, we can server 1024 clients/second. This is, however, even further mitigated by the keepalive_timeout directive.


Thanks for the tutorial. I have a quick question though. I have previously followed this process for a 2GB server and when running ulimit -n I get 1024. I am now following the same process on an 8GB server and the number is the same.


Now to install the S3 graphics driver, start DOSBox again, typecd windowssetupYou get a screen similar to the initial setup of Windows 3.x. Scroll up to the Display driver and hit enter. Now scroll all the way down to "Other (requires disk....)" and hit enter again. Enter the path to the S3 drivers "c:\drivers\s3" and hit enter.You can now choose on of the S3 drivers. The highest working resolution is 1024x768 at 64k colors. For playing games a much lower resolution is enough. Some can't even handle more than 256 colors and will look odd. 041b061a72
