Why learning Haskell/Python makes you a worse programmer
I've found, contrary to what you sometimes read, that learning Python and Haskell has not improved my programming using other languages. Haskell in particular, being so different from imperative languages, is supposed to give new insights into programming that will help you even when you are not using the language. My current experience doesn't exactly tally with this, and here is why:Demotivation.I find I think in Python, and even in Haskell to some extent, even though I have used Has...

JavaScript efficiency catch up
JavaScript is a very flexible language, we can write JavaScript code freely with various styles, different kinds of codes will have different execution efficiency. Here we summarize some tips we get from our development. Efficiency of JavaScript itself JavaScript has execution context chain, closures, prototype inheritance, eval etc. It brings us some magic features, but it also introduces the performance issue, if we don't use them properly, it will affect the codes execution efficiency. 1. Glo...

Ten things I want Siri to be able to do for me
Now that I've had my iPhone 4S for a couple of days, I'm amazed with what Siri can do. I've asked a number of questions -- real ones, not questions like "What is the meaning of life?" -- and have been totally impressed with how my interaction with the iPhone has changed. But there are more things I'd love to be able to do with Siri, which is the reason for this post.Everyone should understand that Siri is currently a beta product from Apple. A lot of the things I'm talking about here should happ...

Concise bash programming skills
The following are some concise bash programming skills which we may need in our daily programming work. 1. Check status of command execution The usual way: echo abcdee | grep -q abcd if [ $? -eq 0 ]; then echo "Found" else echo "Not found" fi Concise way: if echo abcdee | grep -q abc; then echo "Found" else echo "Not found" fi Of course you can remove if...else with following code [Sun Nov 04 05:58 AM] [kodango@devops] ~/workspace $ echo abcdee | grep -q ...
Why isn't all internet traffic encrypted?
The biggest problem is that you must be able to verify that you're encrypting to the correct key. Without it, encryption would be practically useless, as anyone could perform a man-in-the-middle attack on the connection and remain undetected.In typical SSL/TLS, as well as other protocols using X.509, this verification is performed by "certification authorities", which are explicitly marked as "trusted" by web browsers and operating systems. Unfortunately, these CAs usual...

Program Or Be Programmed
On Thursday night I gave a talk at NYU Poly and in the Q&A a young man asked me for advice for "those who aren't technical". I said he should try to get technical. The next morning I met with a bunch of Sloan Business School students doing a trek through NYC. A young woman asked me the same question. I gave her the same answer.I don't mean that everyone should become a software engineer. I do mean that everyone should understand software engineering (or whatever technical...

Cool HTML5 matrix effect
Do you still remember the movie The Matrix? Do you still remember the cool matrix effect in that movie? How is that effect achieved? Shaun Dunne shared a piece of HTML5 code which displays a cool matrix effect. The matrix demo can be found here. Below is the code which he achieves this effect: with var s = window.screen; var width = q.width = s.width; var height = q.height = s.height; var letters = Array(256).join(1).split(''); var draw = function () { q.getContext('2d').fillStyle='rgba(0,0,...
Crazy: 90 Percent of People Don't Know How to Use CTRL+F
This week, I talked with Dan Russell, a search anthropologist at Google, about the time he spends with random people studying how they search for stuff. One statistic blew my mind. 90 percent of people in their studies don't know how to use CTRL/Command + F to find a word in a document or web page! I probably use that trick 20 times per day and yet the vast majority of people don't use it at all."90 percent of the US Internet population does not know that. This is on a sample size of thousa...

Why should we drop or reduce use of MD5?
MD5 is a frequently used one-way hash algorithm, it is commonly used in following situations: Check data integrity. We take hash of the data stored in two different places and compare them. If the hash results are the same, then there is no need to check the actual data. This utilizes the collision-resistant feature. Two different data block will have little chance that their hash values will be the same. Many data service providers use such technique to check repeated data to avoild repeating...
