Server workloads is a bad excuse. Most browsers and a lot of applications use SQLite. Firefox and Chrome is known to write a lot more than they read. http://www.phoronix.com/scan.php?page=article&item=samsung-9...

Consumer based SSD's should be avoided. They are all a big lie when it comes to write performance. Some SSD's are hardly faster than regular hard drives for write operations. https://blogs.technet.microsoft.com/fil

Well at first I thought that you could create an in-memory tablespace. But it doesn't seem like its a good idea though, http://stackoverflow.com/questions/7872693/running-postgresq... So I guess if you need i

Do they have a proper CLI client now? Working with SQL Server is great as long you have SQL Server Management Studio, but not having a CLI client makes me cry when I just want to do something quickly over SSH.

Correct, we may have a few MB of text that is training data. But the trained models are several GB's

This is absolutely true, you can for example run pg_test_fsync to test your fsync performance. On Ubuntu, if you have installed PostgreSQL this is available at /usr/lib/postgresql/9.5/bin/pg_test_fsync I get 40

I'm working for a startup called Boost.ai where we have decided to build our own deep learning model and create our own training data. We use several models that predicts what word comes next, take care of mispellings and dialects. We

I think frameworks like Django, Rails or Grails are excellent tools for building many business applications. Especially when there are plenty of CRUD operations and complex workflows with different administrative roles. These frameworks exc

Recently I had an issue with connection timeouts in my connection pool when using the jTDS driver to connect to the Azure SQL Server service. When I switched to Microsofts updated JDBC driver, that problem was solved immediately.

I also think Java is fine. Compared to C#, I find Java code easier to read as there is less magic. I also use Groovy for some corner cases like for example JDBC stuff or metaprogramming. I'm also a big fan of Maven and the development

I wonder how effective LZ4 would be as default compression algorithm for NTFS. It is extremely effective with ZFS.

PHK has argued that the SSL/TLS libraries we have is a nightmare when it comes security design. He rather favor "jailing" these processes as a separate process. So if hell breaks lose, like with Heartbleed, your Varnish proce

Sounds like you had a gigantic malloc and used too much memory and let Linux kill it. http://stackoverflow.com/questions/16693677/why-isnt-varnish... If you really need a large malloc, I highly recommend running V

In most setups, Varnish will perform a lot better. 10x better performance should be expected for any high traffic site. Varnish is a lot easier to configure if you have some complexity, for example if you want to cache the same page but for

I absolutely agree! While we can discuss about why SCSS is better, it is more like comparing Volvo with Mercedes. In the end, CSS is the standard, not SCSS. And CSS is evolving and getting better and better.

Safari is the new IE6, stop supporting it and let it die. It will not get any better anyway. If most of your users are on iOS, then make an app for them, it's what Apple also want you to do...

This!!!! I cannot believe that Apple is allowed (even by EU) to only allow their own browser on App Store. Having a choice is always good. If it was Microsoft, the story would have been completely different today.

There is a lot of votes here for cloud providers. And while I think AWS is great, it is not great at everything. What I've done recently is buying used servers and 10G/40g network switches from Ebay and rented a colo(colocation) r

With SQL Server I don't get 2000MB/s on the same hardware, more like 600-800MB/s. This is most likely because of LZ4 compression and large block sizes(64k-128k) on ZFS, that results in a lot less IO. Because with SQL Server,

I tested parallel queries on PostgreSQL 9.6 on a few TBs of data, 5 billion rows on an older dual Xeon E5620 server. I also striped 4 Intel S3500 800GB drivers with ZFS and enabled LZ4 compression which has a compressratio of 4x. For a sequ
