Or cheaper Glendronach for that matter? It's 40-60% more expensive than Macallan here.

Perforce has supported concurrent versioning since at least 2001 if not earlier. Individual files could be marked as requiring locks which is useful for binary files for which concurrent changes cannot be merged (one of the big reasons why

I'm not sure articles like this one do non-database professionals any favors by associating unrelated concepts that are often found together such as relational databases and ACID compliance. There are both relational databases that are

I think the article intended to highlight features specific to PostgreSQL. CTEs are undeniably great, especially recursive CTEs, but they're also part of the SQL:1999 standard and available in lots of databases.

Long comment thread on a previous posting: https://news.ycombinator.com/item?id=12166585 TLDR: Uber is using MySQL as part of their "Schemalass" key-value store ( https://eng.uber.com/schemaless-par

LSMs do not guarantee that sequential key/value pairs are stored in the same SSTable so reading "n" k/v pairs, in the worst case, could require seeking through "n" different SSTables. There are datastores that

I have the same setup and it's great for some development tasks, but its single-core speed can't match the latest processors. I actually installed Linux on my company-issued MBP and I run a bunch of dev tools on it via Xwin from m

For those reasons, I like Xfce and LXDE on Xubuntu and Lubuntu, respectively. I use those for workstations, they've got the same CLI features as Ubuntu, and I don't need or want a bunch of GUI chrome in my dev environments.

I'm happy to see that MySQL is progressing, but I think that enumerating its adherence to the latest SQL standards overlooks some of its other serious flaws from the perspective of operations and reliability. Below are two of the worst

Their basic approach for handling time series data -- partition the inserts by time range -- is one that works for pretty much any relational database. If you can treat the data as immutable which is often the case with time series data, it

Yeah, apart from contractors who are between gigs, I can't imagine very many people who can work for a week as part of the hiring process. And even if many applicants could, I think it takes longer, sometimes quite a bit longer, to acc

I'm not sure what you mean by "multi-process DB", but there are plenty of workloads in which SQLite under-performs non-MVCC databases. It is simply not designed for highly concurrent access patterns. In a previous job, I had

I think skill differentials in programming is a contributing factor to the bimodal distribution. I think there's also another factor which is the degree to which one is an active "curator" of one's own career. I've

>>Random distribution seems like it would be better for write performance - it means that inserting multiple new values and rebuilding the index can happen in parallel rather than having to coordinate the auto increments. It also natu

The sequencing of those UUIDs resets every time Windows restarts. Given the frequency of OS and SQL Server updates that require reboots, that wasn't good enough for any of my workloads.

Making blanket generalizations in the title of an article is a terrible idea. Auto-increment integer IDs work for different use cases than UUIDs. This article does a decent job of describing the scenarios where UUIDs work well, but its sect

Given the existing architecture of Aurora, the independent scaling of CPU and storage seems pretty straightforward. What is much harder to scale up and (especially) down is a warmed-up buffer pool which is critical for consistent query perf

It would certainly be nice to disable just that one section. I took the GGP's comment to be about disabling the entire Google Now/Feed app.

FWIW, you can disable Google Now on your phone. On the more recent versions of Android, you long-press an empty spot on your home screen, select "Settings", and then locate and disable the "Your feed" item.

A missing small feature here or there is kind of a lame reason to not take a large and well-respected product seriously. That said, bcp and PowerShell (piping the output of Invoke-Sqlcmd through Export-CSV) are among the more common ways th

That may be the case for other products, but in this case, they acquired the "Sybase SQL Server" product and simply renamed it "Microsoft SQL Server".
