It also discusses checksums, corruption detection, and the role of the write-ahead log. ### Source excerpt It's not a very disputed topic that you should backup your database, and further test your backups. What is a little less discussed, at least for Postgres, is the types of backups that exist. Within Postgres there are two forms of backups and understanding them is a useful foundation for anyone working with Postgres. The two backup types are Physical: which consist of the actual bytes on disk, Logical: which is a more portable format. Let's dig into each a bit more so you can better assess which makes sense for you. Logical backups Logical backups are the most well known type within Postgres. This is what you get when you run pg_dump against a database. There are a number of different formats you can get from logical backups and Postgres does a good job of making it easy to compress and configure this backup how you see fit. When a logical backup is run against a database it is not throttled, this introduces a noticable load on your database. As it's reading the data from disk and generating (in layman terms) a bunch of SQL INSERT statements, it has to actually see the data. It's of note that older Postgres databases (read: prior to 9.3) there were no checksums against your database. Checksums are just one tool for you to help check against data corruption. Because a logical dump has to actually read and generate the data to insert it will discover any corruption that exists for you. This portable format is also very useful to pull down copies from production to different environments. I.e. if you need a copy of production data down on your local laptop pg_dump is the way to do it. Logical backups are also database specific, but then allow you to dump only certain tables. All in all logical backups bring some good features, but come at two cost: Load on your system The backup contains data as of the time when it ran Physical backups Physical backups are another option when it comes to backing up your database. As we mentioned earlier it is the physical bytes on disk ## TIP: Use Tethering to Simulate Slow Network Connections DevFeed: [TIP: Use Tethering to Simulate Slow Network Connections]() Original publisher: [Read original article]() Author: Shai Almog Published: 2017-01-29T00:00:00Z Content type: tutorial Language: en Sources: [CodeName One]() Topics: [Android Studio](), [Mobile](), [debugging](), [Large Screen](), [Networks](), [ide]() Tags: [android](), [android-studio](), [debug](), [debugging](), [hotspot](), [laptop](), [mobile](), [mobile-apps](), [networking](), [performance](), [portable](), [simulator](), [wifi]() ### AI overview This article explains how to use phone tethering and a portable hotspot to simulate slow 3G or 2G network conditions for debugging and profiling mobile applications in the simulator or on a device. ### Source excerpt I recently had to debug some code on Android Studio and was reminded how awful that IDE really is. IntelliJ is a pretty good IDE but Android Studio is remarkably slow even for trivial projects... One of the things that make it slow (besides RAM usage) is the approach of downloading everything it needs dynamically. This might be unnoticeable on Google's fast networks where this probably runs instantly. But on my fast home network this was painfully slow. ## Building Portable Binaries DevFeed: [Building Portable Binaries]() Original publisher: [Read original article]() Author: Square Engineering Published: 2015-06-15T16:09:00Z Content type: tutorial Language: en Sources: [Square Corner Blog RSS Feed]() Topics: [Deployment](), [Linux](), [Python](), [App]() Tags: [binaries](), [dependencies](), [deployment](), [engineering](), [linux](), [portable](), [python]() ### AI overview The article explains how to build portable application binaries by shipping the runtime and dependencies together.

It also describes userspace spinning, kernel sleeping, and portable C++11 implementations for multiple operating systems. ### Source excerpt In multithreaded programming, it's important to make threads wait. They must wait for exclusive access to a resource. They must wait when there's no work available. One way to make threads wait - and put them to sleep inside the kernel, so that they no longer take any CPU time - is with a semaphore. I used to think semaphores were strange and old-fashioned. They were invented by Edsger Dijkstra back in the early 1960s, before anyone had done much multithreaded programming, or much programming at all, for that matter. I knew that a semaphore could keep track of available units of a resource, or function as a clunky kind of mutex, but that seemed to be about it. My opinion changed once I realized that, using only semaphores and atomic operations, it's possible to implement all of the following primitives: A Lightweight Mutex A Lightweight Auto-Reset Event Object A Lightweight Read-Write Lock Another Solution to the Dining Philosophers Problem A Lightweight Semaphore With Partial Spinning Not only that, but these implementations share some desirable properties. They're lightweight, in the sense that some operations happen entirely in userspace, and they can (optionally) spin for a short period before sleeping in the kernel. You'll find all of the C++11 source code on GitHub. Since the standard C++11 library does not include semaphores, I've also provided a portable Semaphore class that maps directly to native semaphores on Windows, MacOS, iOS, Linux and other POSIX environments. You should be able to drop any of these primitives into almost any existing C++11 project. A Semaphore Is Like a Bouncer Imagine a set of waiting threads, lined up in a queue - much like a lineup in front of a busy nightclub or theatre. A semaphore is like a bouncer at the front of the lineup. He only allows threads to proceed when instructed to do so. Each thread decides for itself when to join the queue. Dijkstra called this the P operation. P originally stood for some funny-sounding Dutch wo [Next page]()
