How much math do you need to become a good programmer?

Should I brush up on math?

This may be the dumbest question I have ever posted online. How much math does one actually need to be a good programmer?

Math and python programming have a somewhat misunderstood relationship. Many people think that you have to be good at math or made good grades in math class before you can even begin to learn programming. But how much math does a person need to know in order to program?

Not that much actually. This article will go into detail about the kinds of math you should know for programming. You probably know it already.

For general programming, you should know the following:

Addition, subtraction, division, and multiplication – And really, the computer will be doing the adding, subtracting, dividing, and multiplying for you anyway. You just have to know when you need to do these operations.

Mod – The mod operation is the “remainder” and its sign is usually the % percent sign. So 23 divided by 7 is 3 with a remainder of 2. But 23 mod 7 is 2.

The even/odd mod test trick – If you want to know if a number is odd or even, mod it by 2. If the result is 0, the number is even. If the result is 1, the number is odd. 23 mod 2 is 1, so you know 23 is odd. 24 mod 2 is 0, so you know 24 is even. If x mod 2 is 0, you know that whatever number is stored in the variable x is even.

To get a percentage of a number, multiply that number by the percent number with the decimal point in front of it. So to get 54% of 279, multiple 0.54 * 279. This is why 1.0 often means 100% and 0.0 means 0%.

Know what negative numbers are. A negative number times a negative number is a positive. A negative times a positive is negative. That’s about it.

Know what a Cartesian coordinate system is. In programming, the (0, 0) origin is the top left corner of the screen or window, and the Y axis increases going down.

Know the Pythagorean theorem, and that it can be used to find the distance between two points on a Cartesian coordinate system. The Pythagorean theorem is a^2 + b^2 = c^2. What this usually means in programming is the distance between coordinate (x1, y1) and (x2, y2) will just be sqrt( (x1 – x2)^2 + (y1 – y2)^2 ).

Know what decimal, binary, and hexadecimal numbering systems are. Decimal numbers are the numbers we’re used to that have ten digits: 0 to 9. It’s commonly thought that humans develop this system because we have ten fingers and counted on our fingers.

Computers work with binary data, which is a number system with only two digits: 0 and 1. This is because we build computers out of electronics components where it’s cheaper to make them only recognize two different states (one state to represent 0 and the other to represent 1).

The numbers are still the exact same, but they are written out differently because there are a different number of digits in each system. Because hex has 6 more digits than the 0-9 numerals can provide, we use the letters A through F for the digits above 9. The easiest way to show these number systems is with an odometer. The following three odometers always show the same number, but they are written out differently in different number systems:

You don’t even have to know the math of converting a number from one number system to another. Every programming language has functions that can do this for you.

(On a side note, hexadecimal is used because one hexadecimal digit can represent exactly four binary digits. So since 3 in hex represents 0011 in binary and A in hex represents 1010. This has the nice effect that the hex number 3A (which is 58 in decimal) is written in binary as 00111010. Hex is used in programming because it is a shorthand for binary. Nobody likes writing out all those ones and zeros.)

Error reporting and processing through exceptions is one of Python’s key features. Care must be taken when handling exceptions to ensure proper application cleanup while maintaining useful error reporting.

Python Exception Handling Techniques

Functions and methods are first-class objects in Python, so if you want to pass a function to another function, you can just treat it as any other object.

Recently I started looking into Python's new asyncio module a bit more. The reason for this is that I needed to do something that works better with evented IO and I figured I might give the new hot thing in the Python world a try.

In this tutorial, I will teach you the cause of the error "Could not reserve enough space for object heap" while going through some possible scenarios.

We are talking about APP_KEY, that must be stored in .env file.Either you are missing that key in .env file or you have an incorrect length of the key.

I am using Glassfish-4.0, Netbeans-8. I started trying out a sample enterprise application. I have tried this same tutorial a couple of times trying to get where and when exactly the problem got infused in the application.

Installed Android Studio 3.2 today, open an old project, compile prompt "No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android"

I had a problem with Basset package (website didn’t load, it kept timing out) so I tried to remove it from the

Functions are first-class objects in Javascript. For that reason, they can be assigned to a variable as an expression, passed as a parameter, and much more.

Many of the people can’t justify buying the new processors among the I7 or Ryzen. In this article, we have covered each and every spec that you can compare between these two processors.

Features:- AMD’s Ryzen 7 2700X is an eight-core 16-thread 3.7GHz processor, with a top stock Precision Boost speed of 4.3GHz and a 105W TDP. it's AMD’s top-of-the-line Ryzen processor -- a minimum of until the Ryzen 3000 CPUs arrive with a replacement Zen 2 architecture, reportedly later in 2019.

AMD’s second-generation Zen architecture features support for DDR4-2933 memory, whereas the first-generation Ryzen platform officially supports DDR4-2667. The new architecture also includes improvements to AMD’s SensMI suite, which dynamically adjusts the performance of the CPU to make sure maximum performance efficiency.

SenseMI consists of 5 components: Pure Power monitors temperatures, voltages and currents, and adjusts the facility delivery in real-time to limit power usage; Precision Boost dynamically adjusts the CPU’s frequency in 25MHz increments to match the performance needs of the present task; XFR (eXtended Frequency Range) works with Precision Boost to unlock a better clock ceiling if ample cooling is detected.

The Ryzen 7 2700X features AMD’s second-generation Precision Boost 2, which may address core clocks individually, and it includes XFR2 technology, which now unlocks up to 7 AMD Ryzen 7 2700X vs Intel Core i7-9700K percent more headroom.

Intel gave its Core i7 and Core i9 9th generation CPUs an equivalent eight physical cores. the new Core i7-9700K doesn't support Hyper-threading which suggests that it's half as many threads as its AMD competitor.

The Core i7-9700K features a base frequency of three .6 GHz, which may reach a lift clock of 4.9GHz in single-threaded applications, 4.8GHz across two cores, or 4.7GHz across four cores, and 4.6GHz on all eight cores. We ran DDR4-3466 for our i7-9700K review.

Intel’s 9th generation Core processors now also feature solder-based thermal interface material (STIM), which in theory should improve cooling. The improved thermal interface doesn’t enable much extra headroom for overclocking, but it allowed Intel to feature two extra cores without deploying a smaller manufacturing process. 

There are so many data file managers over there. On ios, AppStore and android google play store contains tons of the data managers. Many of them are provided by the authentic sources and contains many features. But on the ark side, there are many of the managers are corrupted and sending some data of your phone or keep track of your data by using these data managers.

Many corrupted data managers use the file making tactics for keeping a track record. 

How it works?

→ The track of the files can be done by two types. Installing additional files into the platform. OR adding files or extracting constantly for hours and hours.

‘org.codeaurora.btmultisim’ is the most data corrupters are using. It is a file transfer protocol and contains the power of the tackle each anti corrupt software. It causes the overwhelming of the files of gigabytes in the pc or phones.

How to stay away?

→ By using the authentic data managers the data robbery and tracking can be stopped. Google has removed almost each of the data sources. From a loophole, the protocol can enter in the phone.

→ Removing files is also a good idea, but not a solution.
