…software was superior. Neither MS-DOS nor the x86 processors from Intel were better than comparable products. The x86 processor architecture is indeed often considered as ugly . But they were cheap and widespread. Compatibility was the key. PCs with MS-DOS were business standard. They were good enough to run simple word processing and spreadsheet software. Software written for MS-DOS would run on any MS-DOS computer. A lock-in effect with a positive feedback …

…few words about the hardware: I am going to use new the Dell PowerEdge R420 with two Intel(R) Xeon(R) CPU E5-2450 0 @ 2.10GHz, 48GB of RAM and SATA SSD: Kingston HyperX 3K 240 GB.
Workload: I will use two different schemas. The first schema is from sysbench, and the table looks like:
CREATE TABLE sbtest$I (
id BIGINT UNSIGNED NOT NULL,
k INTEGER UNSIGNED DEFAULT '0' NOT NULL,
c CHAR(120) DEFAULT '' NOT NULL,

The register set of Intel processors is saved and restored each time a context switch occurs.
Saving the address of the TCB in a register would be ideal.
x86 and x86_64 processors are notorious for not having many registers available, however Linux does not use the FS and GS segment selectors for segmentation. So, the address of the TCB can be stored in FS or GS if it will fit.
Unfortunately, the segment selectors FS and GS can only store 32-bit addresses and this is why Ulrich…

and to do that, I need to setup some hardware. Big Memory is key, and figuring out
the right processor to maintain low cost is not easy.
Looks like he Intel Core i5-3470 Processor is the idea solution, and using a Q77 based P8Q77-M/CSM with 32 Gig of Ram is idea.
A Synology DS411Slim seems to be idea for a small NAS to drive the testbed.

And in this graph we look at the card's performance on sysbench OLTP:
It is worth noting here that EXT4 outperforms XFS by a fairly significant margin. The approximate raw numbers, in tabular format, are: - EXT4 XFS 13GiB BP 22000 7500 25GiB BP 17000 9000 50GiB BP 21000 11000 75GiB BP 25000 15000 100GiB BP 31000 19000 125GiB BP 36000 25000 …

…working on my wife's Samsung Series 5 Chromebook running an Intel Atom processor. I have a newer ARM-based Chromebook, but there is currently no ARM port of the Dart VM. I used the 32-bit version of the JDK and the 32-bit version of Dart Editor.
I'm pretty excited that this works because this is one of the few things that was preventing me from fully switching to a Chromebook :) Now, all I need to do is get my hands on a Chromebook Pixel !

…evaling Clojure. With the help of the Node-Webkit project out of Intel, we now use Node.js for all of our platform interaction and we rely on chromium to present our UI. There are many reasons we went down this path and ultimately it has worked out really well for us. ClojureScript, though it has had its moments, has generally been a joy to use and has allowed us to keep our codebase incredibly tight and small despite all of the stuff we've managed to build into LT.
