Memory design and virtual memory

In the class of SWE 514 Computer Systems, I am studying low-level concepts about cpu and memory design. Although I am totally abstracted from them in daily programming life, I think If you are a software developer it is good to catch at least a glimpse of how memory management works, regardless you write low-level or high-level programs. In many respect, management burdens are being carried out by operation systems; however, sometimes having knowledge about these may help you in terms of performance or security issues. I am not going to explain what the memory management is here; instead, I will share some useful resources.

The article titled "Principles of virtual memory" by Carl Burch and Hendrix College seems to me that it covers most of sides of virtual memory concept very concisely. After reading it, you will understand why virtual memory exists and which parts of it are actually crucial.

In the following youtube playlist, virtual memory concept is discussed as why we need it and what parts it consists of. You can find general information about paging, page frames, address translation, translation lookaside buffer(TLB), caches, replacement methods by watching the list from the first video to the 14th one.


This article published by University of Maryland covers the conceptual outlines of virtual memory and other related things. There are also other lecture notes about cpu and memory design.

Migrating from PHP to Python

At last, I’ve made a strong decision to migrate from PHP to Python. Leaving a tool, leaving your bread basket would not be an easy decision if you used it almost for eight years. Otherwise, I believe that sometimes with a little bit courage to leave your conform zone and a lot of curiosity you can get a better bread basket, maybe a jar of jam too. if you want to be a sea, you must give up being a drop. Why am I leaving PHP? Actually I am not leaving PHP totally, but switching my primary language to Python because my works have been changing. Most of work required from me is related to natural language processing(NLP), machine learning(ML) techniques. And I, and many other developers, find Python much more capable to deal with this kind of works. It has already many libraries, tools, frameworks for NLP and ML. Another reason is that I think web programming will not grow as much as an intelligent system. Maybe I am wrong, but there is no doubt the future is about intelligent syste...

Memory organization and cache management

Image
In computer systems, caches are used to diminish the slowness of main memory which is larger and cheaper than cache memory. Caches are faster because not far from CPU and not as large as main memory. In modern computers, there may be more than one cache memory. The layers composed a memory hierarchy. The memory hierarchy is sometimes called an illusion to processors because a processor can have as large and fast a memory as it needs at the level of reasonable cost. In short, from a broader perspective it is easy to understand why memory hierarchies are needed; however, to understand how it works you need to narrow the perspective, e.g. taking account only two memory layers at one time. Key concepts are: cache miss and hit ratios. memory and cache and average access speed memory size, cache size block or cache line size set size direct mapping, fully associative mapping, set associative mapping address partitioning (tag bits, index/set bits, block bits) replacement algor...

Predicting game results from fans’ emotions

Image
Facebook’s data science team published a post in which they claim it is possible to predict a football team’s performance mining emotions of its fans. The post tells us before a kick-off, fans seem positive. But the volume of positive emotion is higher in the fans who support the better team. After the match, the winner’s fans feel very high positive emotion, on the other hand other team’s fans feel negative. Actually we do not need any study to predict this correlation between teams and their fans. It is obvious when a team wins, its fans get happy and so they post positive status messages. Yet I think this study is not trivial. Every study does not necessarily bring about a breakthrough.
