A mouthful of a title… but then, I suppose most thesis titles are. It’s been a long time coming, but I’m happy to finally report, it’s official: my thesis for Lund’s Human Factors and Systems Safety program has been published ! Astute followers may be wondering “Hey, wait a second, I thought you graduated last summer? Twitter has the receipts !” Well, I did march with my classmates last summer.

Parallel programming solves big numerical problems by dividing them into smaller sub-tasks, and hence reduces the overall computational time on multi-processor and/or multi-core machines. Parallel programming is well supported in traditional programming languages like C and FORTRAN, which are suitable for “heavy-duty” computational tasks.

Webhosting Compared: Testing The Uptime Of 32 Hosts In 2018. Webhosting Compared: Testing The Uptime Of 32 Hosts In 2018. John Stevens. 2019-02-12T12:00:22+01:00. 2019-04-29T18:34:58+00:00. (This is a sponsored article.) Many surveys have indicated that uptime is number one factor when choosing a web host and although most, if not all, web hosting services “promise” 99.99% uptime, it’s not the case with our case-study.

I recently wrote about the growing fear produced by the mounting performance pressure of the Big Shift. As fear grows we have a natural human reaction to hold onto what we have. While very understandable, that reaction can also be very dangerous and lead us to miss the expanding opportunities created by the Big Shift. The two most prominent images – walls and safety nets - dominating much of our conversation these days are manifestations of our fear and desire to hold onto what we have.

When your software system communicates with external systems or devices, there is good reason to isolate all communication with the external system into a single place and perform the relevant translation there. I call this pattern The Gateway Interchange Context. It’s an independent piece of software that sits conceptually at the edge of your architecture and mediates communication between agents outside the architecture and those within it.

I wrote yesterday about Vitess , a scale-out sharding solution for MySQL. Another similar product is Citus , which is a scale-out sharding solution for PostgreSQL. Similar to Vitess, Citus is successfully being used to solve problems of scale and performance that have previously required a lot of custom-built middleware. Citus solves the following problems for users: Sharding.

One of the most powerful commands that you could learn, grep is essentially a robust search tool. It gets its name from the acronym it stands for which is global regular expression print. This is just a fancy way of saying “to search for specific strings or patterns (using regular expressions) within a specific file or directory and print the matching results”.

SQL Server 2017 leverages up to 4 log writer workers, on hidden schedulers, to assist in transaction log processing activities. You may find the number of log write workers has been increased to 8 when running newer releases of SQL Server to accommodate larger systems. (Caution: Pre-release software may change before final release.). During SQL Server startup the number of log writer workers is determined.

The graphics interchange format, better known as GIF, has been around for longer than the World Wide Web itself. Thanks to their simplicity and widespread support, GIF files remain wildly popular despite the dozens of other image and video formats available today. That said, GIFs can drag down a web page’s performance, especially if not optimized.

When creating a web application that handles user information it is a good idea to protect anything considered sensitive rather than storing it as plaintext within a database. The goal is to make it as difficult as possible for a malicious person to obtain access to this sensitive information. Rather than encrypting sensitive information with the knowledge that it can one day become decrypted, it is better to hash this sensitive data instead because hashing is a one-way process.

SQL Server 2017 introduced a small change to SQL Server’s default worker thread calculation, accounting for smaller environments. When running on smaller environments SQL Server reduces the worker target. For an X64 installation, using the sp_configure ‘max worker threads’ value of 0 SQL Server uses the following calculation. On small environments SQL Server always uses 256 as the target.
