No no and no. Breaking changes are not ok, not even slightly! It's not acceptable after an alpha release, It's especially not acceptable after a beta release. And it is offensive against developers to have breaking changes from th

A release candidate is NOT supposed to have breaking changes.... its a friggin "release candidate". Projects with lot of breaking changes for minor releases should raise red flags, so steer away! Instead of wasting valuable time b

PHK explained the cause of this is that the Linux kernel VM system performs poorly when overcomitted. https://news.ycombinator.com/item?id=10752209 So the conclusion is, as long your malloc fits in your system memory, Varni

Yes and no. It depends on the use case, if you do a lot of updates, you do want a small recordsize(8kb) and if so, you do not benefit greatly from LZ4.

SQL Server performs slightly better than PostgreSQL for analytics. This is mostly because of parallel queries which will still be more efficient on SQL Server when PostgreSQL 9.6 is released. On the other hand, PostgreSQL can take advantage

I really dislike these simple charting libraries, because I always have some kind of issue that just wastes my time in the end. For example with plottable, there is a hover event function that is extremely expensive that will trigger for ev

In Norway, positions from public departments like the tax department usually includes salary range in the job description. They often pay very well too, while at the same time they have a very good description of what expertize they need. I

Actually, I believe there will be a change in cloud storage. There will be less sync of files and more raw block device access. Imagine if your local ISP could offer this with low latency and cost slightly above an external hard drive. Fo

I cannot understand the fuzz about multi-master replication, it either involves dirty/phantom reads, or it is awfully slow. Wikipedia has a lot of examples of these issues https://en.wikipedia.org/wiki/Isolation_%2

ZFS runs fine with just 1GB of ram. Even several terrabytes of storage. When it comes to knowledge about ZFS, avoid about anything that comes from the FreeNAS community. It is quackery at its best.

I think the same about Poul Henning Kamp. I feel I read his name in every module in FreeBSD. Jails, GEOM and so on. And Varnish is a fantastic well though product from him. The architectural difference of how data is stored between Redis an

Patrick from ServeTheHome recently posted that of the 160 used Intel SSD drives he had bought from Ebay. Not a single one has failed yet. Intel, for example, advertises a 0.2% AFR on its data center SSDs which is much lower than observed ha

Among other great performance tips I recommend are: * Don't always create a index for a single column, multi-column indexes can in many cases be a lot faster. * For large tables, I often see that PostgreSQL choose sequential scan inste

Really cool to see active work on patching Ceph to run on FreeBSD. There should be some advantages by running Ceph OSD on ZFS, but there is very little information about if ZFS work well with Ceph even on Linux. Transparent compression and

Thank you for telling us these details. I can't help but I note that you benchmark the drive with a block size of 1024. Minimum block size of a modern SSD is 4096, anything lower would just cause unnecessary load. Also if you want to b

This is so true, some consumer SSD's are so evil that they do not even honor ATA_CMD_FLUSH. Bad things will happen then.

Basically on a PCIe 3.0 x4 maximum performance is 4000GB/s, in practice this is 3200-3500MB/s. With 4k random write, you will get maximum 800.000 to 875.000 iops per second. Consumer-grade SSD's barely manage to write 500-100
