Interesting article about how you can be like able when you only say very little.

One of the early programs I’ve written was the sieve of
Eratosthenes. I tried computing prime numbers up to 2010, but it was
terribly slow. Then, for comparison, I’ve tested prime numbers using
my TI-89 Titanium graphing calculator’s built-in isprime() function,
and it was whopping fast! How? After some preliminary research, I
came upon the sieve of Atkin, which I could see to be understandably
faster due to the use of checking for multiple prime factors with one
divisor of 60.

Now, let me try to explain efficient factoring from first principles, in a very simple manner. Let’s start by discussing even and odd numbers. Every other number is an even number, and every even number is divisible by two. Therefore, half of all numbers in any number space are not prime numbers. Wow, that’s great. 50% of the time, we’ll be able to factor 2 out of an arbitrary numbers. And if we are doing factorization for fraction reduction, this means we will be able to reduce fractions at least a good… 25% of the time. Not great, but right off the bat, that’s a lot better than nothing.
So, let’s keep going with larger integer factors.
- every 2nd number is divisible by 2
- every 3rd bnumber is divisible by 3
- every 5th number is divisible by 5
- every 7th number is divisible by 7
Being organized and moving fast go together.
Procrastinating and being disorganized go together.
You are the maker of many of the problems you face.
Being busy isn’t the same as being productive.
You want to have more spare time, you want to have fun,
but time flies when you’re having fun.
Do the things that you don’t want to do, and you’ll
feel like you have more spare time.
Rather than complaining about your problems, quantify
them and search for efficiency improvements in your tasks.
If you don’t like logging and quantifying, all the better,
doing so will make you feel like you have more spare time.
Take the time to organize, and organize immediately without
procrastination.
If you don’t like doing it, all the better, doing it will
make you have MUCH more spare time.
The long and narrow path is the path to Heaven.
If you do all the things that make your life feel longer and longer
and longer, it might just last forever.
Take the time to organize, and organize immediately without procrastination. If you don’t like doing it, all the better, it will make you feel like you have more time. And when you are done, you will literally be able to accomplish more in the time you have because you will be able to move faster. So your feeling of having more time will be logically confirmed.
Commercial motor vehicles are subject to randomized roadside inspections by police officers, in order to determine that they and the driver are roadworthy. Interesting. Commercial drivers are definitely allowed less “freedom” than the uninitiated may think, but for a good reason, given the safety implications and endemically very high danger of the roads and motor vehicles. Noteworthy is that the introduction of smartphones has made electronic logging much easier for commercial drivers, and “Form and Manner” violations of missing dates on the log basically vanish.
I happened to find this at random when searching for documentation on Chef Inspec.

Interesting, Utah has an emerging tech scene as “Silicon Slopes”? Indeed it does, and some of the companies have a heavy focus on marketing from, you bet it, past Mormon missionaries. Lots of interesting things are saiid in this article, it’s worth a good read of its own right. But inevitably, I am left without summarizing much in my own article.

Being asked the question of how to tell if a newly built house is wired correctly for modern networking, I must admit that you should simply assume it isn’t correctly wired and you will redo it yourself. Typically, they’re building with modern cabling, Cat5 or better, but the design intelligence lags behind. Star topology and cable upgrades are an oversight. In other words, there’s a skills gap that could be solved if the necessary education is universal across all construction teams.
Dissatisfied with with previous math library designs, I made my own that uses generics to support both integer and floating point arithmetic in one package. How do I feel after giving this a first go?
I really like generics programming in C since there are times when I can get both compact object code and an elegant programmer interface at the same time. There are times when I could see how the same advanced math could be more elegantly implemented in C++, but I realize I cannot use it due to the esoteric complexity of C++ compilers for minimal computer systems.
When you run the Python installer on Windows, it typically always wants to request Admin privileges, even if you only want to install for your own user account. But, there is this interesting trick that allows you to run the Python installer without it asking for Admin privileges.
msiexec /a python-3.4.0.msi /qb TARGETDIR=C:\Users\%USERNAME%\python34
Looking at an example X11 software, I see mention of “drepper.” Ulrich Drepper? Wow, he’s been around working in a lot of software. What other things can I find on the Internet about Ulrich Drepper? A lot. Beyond the criticisms of some hostile comments working with others on glibc, Ulrich Drepper has produced a lot of other writings and useful publications.

Also, Ulrich Drepper had quite a number of things to say about Richard Stallman and given insight into why the Linux community does not like the “or any later version” part that you can add for specifying the terms of the GNU General Public license on your software.

Here is another article on the history of Unix, this time from Ars Technica. One interesting point that I wanted to call out from a mere skim of its contents, it mentions that the famous photo of Ken Thompson and Dennis Ritchie at Bell Labs wasn’t published in Scientific American until Ritchie’s hair was less luxuriant and lighter, and the captions were reversed.
