At the Apple Store in my devRant hoodie and got noticed by an employee..
Her: what's your username?
Me: brod 😬, what's yours?
Her: julia! Have you seen the new MacBook Pro?
Turns out, there's no @julia, now I have a $2,800 MacBook that I didn't need (nope, not the pro, just the shit one).53
Assembly: He’s the nerd. He speaks very quickly and uses short sentences. Very few people talk to him. He’s considered to be an autist asperger by a majority of the class because he finishes the exams so quickly it’s insane and he faces a lot of difficulties in speaking with others. He’s at school but already dressed like an engineer.
Ada: She’s a foureyes nerd. When she gets the answer she’s doesn’t make any mistake. Ada often corrects the teacher when she writes a line a little ambiguous. She’s building a rocketship in her backyard and she’s always speaking about this weird hobby.
Python: He’s Mr Popular. He likes skate, brags about all the parties he’s invited to. He’s good in all the subjects taught in class but he’ll do them a bit slower than the others. Everyone loves him because he explainsthings so well, sometimes the teacher herself asks Python to explain some part of the course. He’s dressed with a hoodie, a baggy and glasses on the top of the head ;)
Java: She is one of the toppers of the class and very popular. She’s very good in all the topics. The teacher loves her but she’s a very talkative person.
Scala/Kotlin: They are twin sisters and the best friends of Java. Unfortunately, they are not as popular and it’s often Java who takes the lead in the group. It’s very difficult to distinguish one from another. Both are far less talkative than Java but Scala speaks a bit differently than Kotlin and Java.
C: He’s the topper of the class. He’s so fast in completing the exams that the teacher really thinks he’s copying Assembly’s work. He has a little brother C++ and they share a lot in common together. He’s the chess major and often plays chess with Assembly and his big brother.
Go: He’s the new kid on the bloc. He doesn’t like C++ and his friends and he wants to prove he can do better than them. Of course, he prefers playing Go over Chess.
APL: He’s a lonely guy. No one understands him when he speaks. Even the teacher is surprised when APL shows a correct answer after several lines of incomprehensible pictograms. People think that he was born in a foreign country… or a foreign planet ?
HTML/CSS: These twin brothers are very different. One is dressed in black and white and the other is dressed with everything except black and white. HTML is very talkative and annoying and the CSS is very artistic. CSS is the best student in Art lessons and HTML performs well in written expression.
LaTeX: She’s friend of HTML. The teacher likes her because she has a gift of writing. LaTeX likes the mathematical courses because she can draw fancy greek letters. The teacher knows this well and she is often asked to write a formula on the black board.
VBA: He’s in the back, looking through the windows. Not really interested in the courses taught in class. In the exams, he answers always with a table.
C#: He’s in the back playing yet another game on his smartphone. He likes being next to the windows also.
Haskell: He’s a goth. Dressed up in dark. Doesn’t talk to anyone. He doesn’t understand why others write pages when he can write a couple of lines to answer the same question.
Julia: She’s the newest student here. She doesn’t have any friends yet but her secret aim is to be as popular as Python and as fast as C.

Vacation in Delphi
After a basic cup of java, I wanted to go to the c and meet Ada, who cured her common lisp with a batch of elixir. On the way, I had a swift Smalltalk with Pascal, who has a brainfuck, because he is a wyvern enthusiast.
I also found a shell with a perl in it, but it had a scratch. This reminded me of my friend Ruby, who has a pet python and loved a good scheme à Shakespeare.
I then started my laptop, which already collected rust on its logo of a maple, and browsed the web for groovy songs. I found a song by Julia, performed in a very high octave in F#.4
"4096 bit ~ 96 hours is what he said.
IDK why, but when he took the challenge, he posted that it'd take 36 hours"
As @cbsa wrote, and nitwhiz wrote "but the statement was that op's i3 did it in 11 hours. So there must be a result already, which can be verified?"
I added time because I was in the middle of a port involving ArbFloat so I could get arbitrary precision. I had a crude desmos graph doing projections on what I'd already factored in order to get an idea of how long it'd take to do larger
@p100sch speculated on the walked back time, and overstating the rig capabilities. Instead I spent a lot of time trying to get it 'just-so'.
Worse, because I had to resort to "Decimal" in python (and am currently experimenting with the same in Julia), both of which are immutable types, the GC was taking > 25% of the cpu time.
Performancewise, the numbers I cited in the actual thread, as of this time:
largest product factored was 32bit, 1855526741 * 2163967087, took 1116.111s in python.
Julia build used a slightly different method, & managed to factor a 27 bit number, 103147223 * 88789957 in 20.9s,
but this wasn't typical.
What surprised me was the variability. One bit length could take 100s or a couple thousand seconds even, and a product that was 1-2 bits longer could return a result in under a minute, sometimes in seconds.
This started cropping up, ironically, right after I posted the thread, whats a man to do?
So I started trying a bunch of things, some of which worked. Shameless as I am, I accepted the challenge. Things weren't perfect but it was going well enough. At that point I hadn't slept in 30~ hours so when I thought I had it I let it run and went to bed. 5 AM comes, I check the program. Still calculating, and way overshot. Fuuuuuuccc...
So here we are now and it's say to safe the worlds not gonna burn if I explain it seeing as it doesn't work, or at least only some of the time.
Others people, much smarter than me, mentioned it may be a means of finding more secure pairs, and maybe so, I'm not familiar enough to know.
For everyone that followed, commented, those who contributed, even the doubters who kept a sanity check on this without whom this would have been an even bigger embarassement, and the people with their pins and tactical dots, thanks.
So here it is.
A few assumptions first.
Assuming p = the product,
a = some prime,
b = another prime,
and r = a/b (where a is smaller than b)
w = 1/sqrt(p)
(also experimented with w = 1/sqrt(p)*2 but I kept overshooting my a very small margin)
x = a/p
y = b/p
1. for every two numbers, there is a ratio (r) that you can search for among the decimals, starting at 1.0, counting down. You can use this to find the original factors e.x. p*r=n, p/n=m (assuming the product has only two factors), instead of having to do a sieve.
2. You don't need the first number you find to be the precise value of a factor (we're doing floating point math), a large subset of decimal values for the value of a or b will naturally 'fall' into the value of a (or b) + some fractional number, which is lost. Some of you will object, "But if thats wrong, your result will be wrong!" but hear me out.
3. You round for the first factor 'found', and from there, you take the result and do p/a to get b. If 'a' is actually a factor of p, then mod(b, 1) == 0, and then naturally, a*b SHOULD equal p.
If not, you throw out both numbers, rinse and repeat.
Now I knew this this could be faster. Realized the finer the representation, the less important the fractional digits further right in the number were, it was just a matter of how much precision I could AFFORD to lose and still get an accurate result for r*p=a.
Fast forward, lot of experimentation, was hitting a lot of worst case time complexities, where the most significant digits had a bunch of zeroes in front of them so starting at 1.0 was a no go in many situations. Started looking and realized
I didn't NEED the ratio of a/b, I just needed the ratio of a to p.
Intuitively it made sense, but starting at 1.0 was blowing up the calculation time, and this made it so much worse.
I realized if I could start at r=1/sqrt(p) instead, and that because of certain properties, the fractional result of this, r, would ALWAYS be 1. close to one of the factors fractional value of n/p, and 2. it looked like it was guaranteed that r=1/sqrt(p) would ALWAYS be less than at least one of the primes, putting a bound on worst case.
The final result in executable pseudo code (python lol) looks something like the above variables plus
while w >= 0.0:
if (p / round(w*p)) % 1 == 0:
x = round(w*p)
y = p / round(w*p)
if x*y == p:
w = w + i
Still working but if anyone sees obvious problems I'd LOVE to hear about it.39
Wish me luck!
If you wanna learn with me I'd love some company.
If you got some great tips let me know!4
Definitely Rust, and a bit Haskell.
Rust has made me much more conscious of data ownership through a program, to the point that any C/C++ function I wrote that takes a pointer nowadays gets a comment on ownership.
I wish it was a bit less pedantic about generics sometimes, which is why I've started working on a "less pedantic rust", where generics are done through multiple dispatch à la Julia, but still monomorphising everything I can. I've only started this week, but I already have a tokenizer and most of the type inference system (an SLD tree) ready. Next up is the borrow checker and parsing the tokenized input to whatever the type inference and borrow checker need to work with, and of course actual code generation...
Haskell is my first FP language, and introduced me to some FP patterns which, turns out, are super useful even with less FP languages.
NEW 6 Programming Language 2k16
Golang Programming Language from Google
Let's start a list of six best new programming language and with Go or also known by the name of Golang, Go is an open source programming language and developed by three employees of Google and the launch in 2009, very cool just 3 people.
Go originated and developed from the popular programming languages such as C and Java, which offers the advantages of compact notation and aims to keep the code simple and easy to read / understand. Go language designers, Robert Griesemer, Rob Pike and Ken Thompson, revealed that the complexity of C ++ into their main motivation.
This simple programming language that we successfully completed the most tasks simply by librariesstandar luggage. Combining the speed of pemrogramandinamis languages such as Python and to handalan of C / C ++, Go be the best tools for building 'High Volume of distributed systems'.
You need to know also know, as expressed by the CTO Tokopedia namely Mas Leon, Tokopedia will switch to GO-lang as the main foundation of his system. Horrified not?
eh not watch? try deh see in the video below:
Swift Programming Language from Apple
Apple launched a programming language Swift ago at WWDC 2014 as a successor to the Objective-C. Designed to be simple as it is, Swift focus on speed and security.
Furthermore, in December 2015, Swift Apple became open source under the Apache license. Since its launch, Swift won eye and the community is growing well and has become one of the programming languages 'hottest' in the world.
Learning Swift make sure you get a brighter future and provide the ability to develop applications for the iOS ecosystem Apple is so vast.

Rust Programming Language from Mozilla
Developed by Mozilla in 2014 and then, and in StackOverflow's 2016 survey to the developer, Rust was selected as the most preferred programming language.
Rust was developed as an alternative to C ++ for Mozilla itself, which is referred to as a programming language that focus on "performance, parallelisation, and memory safety".
Rust was created from scratch and implement a modern programming language design. Its own programming language supported very well by many developers out there and libraries.
Julia Programming Language
Julia programming language designed to help mathematicians and data scientist. Called "a complete high-level and dynamic programming solution for technical computing".
Hack Programming Language from Facebook
Hack is another programming language developed by Facebook in 2014.
Social networking giant Facebook Hack develop and gaungkan as the best of their success. Facebook even migrate the entire system developed with PHP to Hack
Facebook also released an open source version of the programming language as part of HHVM runtime platform.
Scala Programming Language
Scala programming termasukbahasa actually relatively long compared to other languages in our list now. While one view of this programming language is relatively difficult to learn, but from the time you invest to learn Scala will not end up sad and disappointing.
The features are so complex gives you the ability to perform better code structure and oriented performance. Based programming language OOP (Object oriented programming) and functional providing the ability to write code that is capable of evolving. Created with the goal to design a "better Java", Scala became one behasa programming that is so needed in large enterprises.3
My favorite OpenSource project is Julia (www.julialang.org). As a physicist, I could never really befriend myself with OOP. With Julia I can write beautiful Code, which I also understand (with full UTF-8 support).
In Python you write pseudo code in Julia you write math.
In Addition, there is an optional package on Github for every fuck which can be handled by the integrated package manager (like using QML, Distributions, Databases, HTTP Server, and so on...)4
I tried to compare Python and Julia by letting them calculate the first 200000000 prime numbers. The result is dumbfounding.
Python: 95.91282963752747 seconds
"Wow! It is awesome! It's like a Python but fast, function composition is so useful..."
Then you realize that arrays start at 1:
"WHAT THE F! WHY?!"4
Julia is a smelly pile of steaming shit.
Jesus fucking christ would you look at that pile of pure utter shit. The dumbfuck dev somehow managed to break WHILE loops for devs coming from python, and I speak for myself and probably others when I write most of us python developers are functionally braindead. If you can somehow fuck it up for python devs, a significant portion of the people you're trying to attract (owing by the syntax), then you should probably just go head and delete your whole git repo now.
Julia is a prime example of why you don't listen to your users on fucking github about the direction of language development.
What a bunch of fucking booger eating retards.33
If Angela Merkel, Julia Gillard and Bernie Sanders were in charge of the internet, what would change?28
So I was reading Julia lang's documentation and got mildly triggered due to this, but then they are not web designing project so I guess it's okay5
what the hell this friendo just sent me a 100 line Julia function with variables names like `sauce` and `thingy` and expected me to debug it. And I guess his tab key was broken cause there was no indentation at all. Did I mention I’ve never used Julia in my life? Is this just Julia culture?7
What would be the best "hot"/upcoming languages for a final year college project?
The project will focus on reverse engineering.
Basic Example: Intercepting signals from products such as a toy helicopters/drones/etc, reverse engineer the signals and try gain control of the device from that.
That's just a very basic function and there will be much more to it, but I'm struggling to decide on a language to pursue hand-in-hand with this project!
I hear Rust, Go, Julia and co being tossed around a lot.
Any suggestions would be helpful!
I really like Julias typesystem, but method dispatch makes it easy to accidentally match against methods you didn't intend.2
Julia's mutlithreading macro is soooo awesome and clean for when you want to do computation work :33
Opinion: Julia will not catch on, because the two language problem is not a big issue for most people in the industry, and most python data scientist will refuse to migrate.
I just heard about "Julia Programming language" where they're kinda combining speed of C and usability of Python into one language. Just wanted to ask how big is it? Does anyone has anything to share on this topic?4
How many languages do you really know... I'd say 7 for myself
bit of c an java (count them as 0.5)
Get on my level 😉 seriously thou, what would you guys say you really know?34
Any people using Julia here for something real. Like analysis or building applications? Is it worth learning or should I stick to python and cpp ?2
Any good programming language with great generics support that is not dynamic ?
Rust generics sucks so much I puked 2 times.
Tried with swift and it looks great.
Golang doesn’t have them.
Maybe I try julia if someone say it’s cool.
I want to implement some 2d vector algebra and simple physics engine.
I started by creating generic 2d vector and trying to create dot product from it.
I didn’t wanted to do it in swift but wasted 2 days trying to do it in rust vs 1 hour in swift including 49 minutes of installing swift tools.
Anyway anyone know performant language with good generics support, let me know in comments.41
Question: what's your opinion on Julia? It seems promising, the macro syntax is neat. But would you use it for data analysis/management or general purpose development?
This year I and two friends joined modelling competition for uni students called SCUDEM. We are modelling refugee settlements and the crime rate in Uganda. I try to lead the group as the previous year and we changed one team member. The model is written in Julia and it is 2k of working lines after week, we work on it in our spare time.
However, one friend who hasn’t done any bigger project in the past or wasn’t programming for money disagree with the workflow. He prefers doing some small models separately. He doesn’t write clear code and it is difficult to read it afterwards. His ideas are good, but he likes more to talk about the problems than straight code them down in the way that we can use it in the bigger structure.
Do you any ideas on how to motivate him to take part in the collective workflow? I feel that working separately is rather contra-productive.2
Anyone here experienced with Travis-CI? I am getting this error. Please help me out.
