  What to Know About Windows 11

Windows 11 launched in October, with Microsoft bringing some changes to the operating system. It was the first name change in six years, and the rollout began on October 5. The rollout is being phased on eligible devices.  You can download it if you don’t want to wait for it to be your device’s turn.  Some businesses are opting to defer upgrades to Windows 11, as are some individuals. Others are excited to take advantage. The following are some things to know about impleme...

  My love… for Expressive Programming Languages

I started out my journey with programming as a teenager learning GW-BASIC. Soon I learnt C language followed by C++.  I was impressed with the OO syntactic constructs C++ had on offer but I felt a little uneasy with a few constructs such as the scope resolution. I started studying Java. It immediately caught my attention with the syntactic improvements and simplifications it brought over C++. I was still in academics, so learning(precisely trying) programming languages on su...

  Is coding going to die?

There is always a voice recent years saying that coding will gradually die, software development is more like an assembly job. i.e, programmer will be more and more like IT engineers. They seldom build something from scratch, instead they achieve the goal by assemble different components. There are people who have similar views around me. From the book "Clean code" written by Robert C Martin-- "One might argue that a book about code is somehow behind the times—that code is no longer...

   Python – parallelizing CPU-bound tasks with multiprocessing

In a previous post on Python threads, I briefly mentioned that threads are unsuitable for CPU-bound tasks, and multiprocessing should be used instead. Here I want to demonstrate this with benchmark numbers, also showing that creating multiple processes in Python is just as simple as creating multiple threads. First, let’s pick a simple computation to use for the benchmarking. I don’t want it to be completely artificial, so I’ll use a dumbed-down version of factorization...

  Will Artificial Intelligences Find Humans Enjoyable?

Will AIs find humans interesting, enjoyable, and worthy of companionship? My guess: the smarter and more autonomous they become the more the answer will become NO. There are practical reasons for AIs to want to understand humans: The AIs will want to protect themselves from all threats, including human threads. The AIs will also want to get more resources (e.g. energy, raw materials for fabrication of additional computing power). The extent that humans control access to resources AIs will...

  Learning Is More Important Than Knowing

Although DuckDuckGo's success is based more on ideology than technology, you'd have to be a pretty arrogant technologist to not appreciate and be impressed with what this small team (for a long time, 1 person) has accomplished. And while DuckDuckGo teaches us a number of valuable lessons (about business, and privacy), to me, the most important, is that good programmers should be measured by what they can learn, not what they already know. Gabriel Weinberg, DuckDuckGo's creator, has been wo...

  Only 4G can resolve the conflicts between China Telecom Carriers and WeChat ?

Why WeChat has made the three big Chinese telecom companies uncomfortable? Let's analyze from both technical and commercial levels. From a technical point of view, Mr. Huang, Dean of China Mobile Research Institute, described the impact of "always online service" applications like WeChat. Instead of using technical terms, we will explain in simple vivid phrases. First, mobile QQ, or WeChat, will have their own "request frequency". These requests are sent to the carrier network, to check the re...

  File System vs Core Data: the image cache test

Code for this project is on GitHub While doing a full re-write of Droplr's iOS app for the 2.0 launch, I couldn't find any good file/image caches out there had a particular feature I really wanted: extending item expiration whenever it's touched. I set out to write my own — which wasn't that much of a challenge — but somewhere along the process I had this crazy idea that perhaps (SQLite-backed) Core Data would be a much better tool for the job: No mismatch between cache index ...

  Cache Reheating - Not to be Ignored

An important aspect to keep in mind with databases is the cost of cache reheating after a server restart. Consider the following diagram which shows several cache servers (e.g., memcached) in front of a database server.This sort of setup is common and can work quite well when appropriate; it removes read load from the database and allows more RAM to be utilized for scaling (when the database doesn’t scale horizontally). But what happens if all the cache servers restart at the same time, s...

  Big file transfer in Linux

It's very common that we need to transfer files between two different hosts such as backups. It is also an very simple task, we can use scp or rsync to complete the task well. But what if the file is very big, it may take some time to transfer it. How can we transfer a big file with high speed? Here we propose one solution. Copy file If we copy one uncompressed file, then we should follow below steps: Compress data Send it to another host Uncompress the data Verify the data integrity This will...
