--- HTTP/3 is coming! And it won't use TCP! ---
A recent announcement reveals that HTTP - the protocol used by browsers to communicate with web servers - will get a major change in version 3!
Before, the HTTP protocols (version 1.0, 1.1 and 2.2) were all layered on top of TCP (Transmission Control Protocol).
TCP provides reliable, ordered, and error-checked delivery of data over an IP network.
It can handle hardware failures, timeouts, etc. and makes sure the data is received in the order it was transmitted in.
Also you can easily detect if any corruption during transmission has occurred.
All these features are necessary for a protocol such as HTTP, but TCP wasn't originally designed for HTTP!
It's a "one-size-fits-all" solution, suitable for *any* application that needs this kind of reliability.
TCP does a lot of round trips between the client and the server to make sure everybody receives their data. Especially if you're using SSL. This results in a high network latency.
So if we had a protocol which is basically designed for HTTP, it could help a lot at fixing all these problems.
This is the idea behind "QUIC", an experimental network protocol, originally created by Google, using UDP.
Now we all know how unreliable UDP is: You don't know if the data you sent was received nor does the receiver know if there is anything missing. Also, data is unordered, so if anything takes longer to send, it will most likely mix up with the other pieces of data. The only good part of UDP is its simplicity.
So why use this crappy thing for such an important protocol as HTTP?
Well, QUIC fixes all these problems UDP has, and provides the reliability of TCP but without introducing lots of round trips and a high latency! (How cool is that?)
The Internet Engineering Task Force (IETF) has been working (or is still working) on a standardized version of QUIC, although it's very different from Google's original proposal.
The IETF also wants to create a version of HTTP that uses QUIC, previously referred to as HTTP-over-QUIC. HTTP-over-QUIC isn't, however, HTTP/2 over QUIC.
It's a new, updated version of HTTP built for QUIC.
Now, the chairman of both the HTTP working group and the QUIC working group for IETF, Mark Nottingham, wanted to rename HTTP-over-QUIC to HTTP/3, and it seems like his proposal got accepted!
So version 3 of HTTP will have QUIC as an essential, integral feature, and we can expect that it no longer uses TCP as its network protocol.
We will see how it turns out in the end, but I'm sure we will have to wait a couple more years for HTTP/3, when it has been thoroughly tested and integrated.
Thank you for reading!27 -
Me: *listening to some random semi-obscure track on spotify, liking it, add it to playlist*
Come home, girlfriend playing the same track. "Yeah I've had that in my playlist for two weeks now". Our accounts are not linked in any way, and I only use Spotify on a PC at work, while my girlfriend only uses it at home.
It might just be coincidence, or us having similar tastes.
But the issue is that it's getting more and more difficult to know whether me and my girl are spiritually linked unique snowflake soulmates who are so perfectly in sync with each other, or whether an algorithm suggestively linked us both that song based on scraped location and behavior data.
And whether it matters. Maybe it matters. I don't know yet.
In twenty years maybe humans will be unsure whether it was a wonderful coincidence bordering on cosmic fate that you ran into your new love, or whether Google purposefully drove you towards the same lunch cafe at a specific time because it calculated that she was the perfect candidate to strengthen your susceptibility to advertisements over the coming decade.
Malicious AI will not come into lives bearing guns.
It will not instantly take all of our jobs and enslave us.
It will just know you better than you know yourself, it will know everyone around you better than you know them, and it will play incredible mind games. It will not be designed with malicious intent, just perfectly execute on top of the malicious systems we already have, and even arise as an emergent property within new systems.
It will rarely be clearly visible, but you will increasingly say to yourself: "That's odd, I was just thinking about that". It will detect depression from a smile, physical attraction from a glance, reliability from patterns in your voice and illness from the bloodflow in your cheeks.
It will not just make our cars autonomous, it will make our lives autonomous. It will protect us, decide for us, keep revenues and human satisfaction in a "balanced maximized" state, it will make everything feel easy, slightly abuse us, and when one of us suddenly crashes at 140 mph into depression, debt or addiction it will prove impossible to know whether the humans or the algorithms were at fault.
I'm incredibly afraid and excited about the coming 10 years.13 -
Simplicity is a prerequisite for reliability.
I put those words on the wall in giant vinyl letters, and I point to them every time someone asks me "can you add a frontend button which checks this external API and stores the correlation between the amount of rain and the sales numbers of purple buttplugs inside the user profiles?"
People always ask for one more column in a table, one more paragraph under an image — they never ask for replacement or removal of items.
So I force them. Want a feature? Fine, if you point at something of equal or greater complexity to delete.2 -
Holy shit. Germany really is a third-world country in regards to connection speeds and reliability. I am visiting my dad this summer, that's why I'm here in the first place. Germany has the most unstable GSM/EDGE connections I have ever seen and everytime I go to Germany, I get reminded of that. Sure, they are slow by design, but in Austria, you can at least use them! In Germany, you

Most programming shirts/hoodies really suck. They fall into two categories:
1. Super lame pun quotes in an ugly font.
2. Memes transfer-printed onto cheap fabric
I'm not against puns, or quotes. I quite like the design from @AlexDeLarge
https://devrant.io/rants/830390/, and I've been looking for a nice shirt with Dijkstra's "simplicity is a prerequisite for reliability" on it.
But many do not put any thought into beautiful design, and shit like "No place like 127.0.0.1", "404 girlfriend not found" or "There are 10 kinds of people" really stopped being funny a decade ago.
Good design, colors & quality are so fucking important.

why do i have an iphone?
well, let's start with the cons of android.
- its less secure. this isn't even arguable. it took the fbi a month or something (i forget) to break into an ios device
- permission, permissions, permissions. many of the android apps i use ask for the not obscure permissions.
· no, you don't need access to my contacts
· no, you don't need access to my camera to take notes
· no, you don't need access to my microphone to send messages
· no, you don't need access to my saved passwords to be a functioning calculator
- not being able to block some apps from an internet connection
- using an operating system created and maintained by an advertising company, aka no more privacy
- i like ios's cupertino more than material design, but that's just personal preference
pros of ios:
- being able to use imessage, at my school if you don't have an iphone you're just not allowed to be in the group chat
- the reliability. i've yet a data loss issue
- the design and feel. it just feels premium
- if i could afford it, ios seems like a lot of fun to develop for (running a hackintosh vm compiled a flutter app 2x as fast as it did on not-a-vm windows)
so that's why i like iphones

I am tired of people shi**ng all over Windows and Microsoft. Microsoft runs probably the biggest website and cloud environment in the world. And guess what? On Windows servers. The company I work for has 200,000 employees and many massive data centers with trillions of client records. And we run a 100% Microsoft environment.
I would imagine that any sys admin or developer can appreciate such scale and reliability.17 -
Biggest mistake I've made in my life is assuming other people knew more than me and asking for advice and integrating their advice. I suffered many years being tortured by terrible advice that had no actual relation or usefulness in reality but caused me stress to have to follow, and I was too inexperienced to know any of this.
The other problem with bad advice is; how do you know it's bad advice? If you got the advice when you were naive, and you followed it, never strayed from it, you will still be naive in that area, because of the dutifulness by which you stuck to that advice. You literally imprison yourself, forever, especially if you are very good at putting effort in and have high conscientiousness, reliability. You will never know you were wrong.8 -

After this weekend's work with React and Material UI, I started thinking about the downsides to going that route (particularly social media sharing & SEO). The obvious solution is to render server-side, but then you have to ask yourself...is there really a benefit to all of this, or are we just coming full-circle and pretending this is better? I'm all for something that improves maintainability, performance, and reliability, but I feel the more I try to keep up with the latest fads, the slower I work, the more compiling and caching b.s. I have to deal with, and the less I trust the final product to "just work". Anyone else feel this way?4

It's utterly frustrating to work with someone who has been in the same job for five years but still hasn't bothered to learn the basic tools necessary to do their job effectively. It's like they're stuck in a time warp, refusing to adapt and improve their skills.
How can you possibly expect to be successful in your career if you're not willing to invest time and effort into learning the tools of your trade? It's not rocket science, and these tools are there to make your job easier, not harder.
And what's worse is when these same people complain about their workload, blaming the tools for their inefficiency. Well, guess what? If you took the time to learn how to use them properly, maybe you wouldn't be drowning in work right now.
It's not even about being tech-savvy or a quick learner. It's simply about taking some initiative and responsibility for your own professional development. It's about having the basic level of competency required for your job.
Not to mention that constantly asking for help and guidance on tasks you should be able to handle on your own is not only a waste of your colleagues' time but also reflects poorly on your work ethic and reliability.
So, please, if you've been in the same job for five years and still struggle with basic tools, do yourself and your team a favor and take the time to learn them. It will make everyone's lives easier and improve your chances of success in the long run. Don't stay stagnant and hold yourself back – embrace opportunities to learn and grow. Your career will thank you for it.
The tools in question is Kubernetes and it's directly related to the persons day-to-day work (SWE + SDET mainly), 5 years is more than enough time to learn and adapt to a new toolset, and yet this particular person refuses to invest time into it. It's frustrating, to say the least, but also a disservice to themselves as they are limiting their potential and hindering their own career growth.3 -
A Rant that took my attention on MacRhumors forum.
.
I pre-calculated projected actual overall cost of owning my i5/5/256 Haswell Air, which I got for $1500.
After calculations, this machine would cost me about $3000 for 3 years of use.
(Apple Care, MS Office Business, Parallels, Thunderbolt adapter to HDMI, Case... and so on).
Yea... A lot of people think it's all about the laptop with Apple. nah... not at all. There's a reason Apple is gradually dropping the price of their laptops.
They are slowly moving to a razor and blade business model... which basically is exactly what it sounds like - you buy the razor which isn't too expensive, but you've got no choice but to buy expensive additional blades.
I doubt Apple is making much money from laptop sales alone... well definitely not as much as they were making 5 years or so ago (remember the original air was about $1800 for base model, and if i remember correctly - $1000 additional dollars to upgrade to 64GB SSD from the base HDD.
Yes, ONE THOUSAND DOLLARS FOR 64GB SSD!
Well, anyways, the point is that Apple no longer makes them BIG bucks from the laptop alone, but they still make good profits from upgrades. $300 to go to 512GB SSD from 256, $100 for 4GB extra ram, and $150 for a small bump in processor. They make good profits from these as well.
But that's not where they make mo money. It's once you buy the Macbook, they've got you trapped in their walled garden for life. Every single apple accessory is ridiculously overpriced (compared to market standards of similar-same products).
And Apple makes their own cables and ports. So you have to buy exclusively for Apple products. Every now and then they will change even their own ports and cables, so you have to buy more.
Software is exclusive. You have no choice but to buy what apple offers... or run windows/linux on your Mac.
This is a douche level move comparable to say Mircrosoft kept changing the usb port every 2-3 years, and have exclusive rights to sell the devices that plug in.
No, instead, Intel-Microsoft and them guys make ports and cables as universal as possible.
Can you imagine if USB3.0 was thinner and not backwards compatible with usb2.0 devices?
Well, if it belonged to Apple that's how it would be.
This is why I held out so long before buying an apple laptop. Sure, I had the ipod classic, ipod touch, and more recently iPad Retina... but never a laptop.
I was always against apple.
But I factored in the pros and cons, and I realized I needed to go OS X. I've been fudged by one virus or another during my years of Windows usage. Trojans, spywares. meh.
I needed a top-notch device that I can carry with me around the world and use for any task which is work related. I figured $3000 was a fair price to pay for it.
No, not $1500... but $3000. Also I 'm dead happy I don't have to worry about heat issues anymore. This is a masterpiece. $3000 for 3 years equals $1000 a year, fair price to pay for security, comfort, and most importantly - reliability. (of course awesome battery is superawesome).
Okay I'm going to stop ranting. I just wish people factored in additional costs from owning an a mac. Expenses don't end when you bring the machine home.
I'm not even going to mention how they utilize technology-push to get you to buy a Thunderbolt display, or now with the new Air - to get a time capsule (AC compatible).
It's all about the blades, with Apple. And once you go Mac, you likely won't go back... hence all the student discounts and benefits. They're baiting you to be a Mac user for life!
Apple Marketing is the ultimate.

How many of you fellas have thinkpads? Bought this refurbished unit about a month ago and the machine is great, really. Very happy with its performance, sturdiness & reliability.
Only thing I'm not too psyched about is the battery life. Probably need a new one as I'm hitting about 4 hours max on a 6cell.
Running Xubuntu 16.04, might switch distros as quite there are a few bugs in the new release but at the same time I don't wanna downgrade to 14.04.

Acer vs MSI Laptops.
Five years ago I bought an acer aspire vn7-591 laptop in Redcoon. It was the expensive laptop I bought ever in those days. My experience at the beginning was really bad because the battery laptop crashed after few months and the screen had some vague/dead pixels, but the worst was the imminent bankruptcy of Redcoon. So I couldn't use the warranty. Anyway, It didn't bother so much I have been enjoying this laptop and still doing it. However, last year the screen put me on alert since it started to fail with vertical bars and color changes.
It was time to buy a new computer and due to the problems with some of the components, I've decided to buy a laptop from a company with a better reputation than Acer in aspects as the reliability of the components.
My choice was a Msi Prestige 15 because of the thunderbolts, since the rest of specs are 'more or less similar', although it has more updated hardware, it is lighter, battery holds up to 4-5 hours etc... But... It is really noisy compared to my Acer computer. 2 CPU fans are around 3000 rpm in idle state... Acer seems to be working without using the fans if you are doing intensive work. I google it as I thought it was a factory problem, but it seems to be not a malfunctioning... In fact I found other users complaining about the same and the community proposed to reduce the fan speed through software.
Right now I have both laptops working and since the new boy is in house, Acer is working flawlessly. I am preparing the Acer for my girlfriend as a gift, otherwise it is a pitty to shut it down and store it in a wardrobe.
So, this is my impression about ACER and MSI. I m still experiencing with the new laptop, but I find weird things like the fan speed or how hot it gets in idle despite it uses a new generation of intel i7 cpu with lower consumption... I should monitor the power consumption...8 -
I prefer it doing 2 tasks parallely during the initial phase of requirement gathering and design phase.(makes more sense if you are working extremely new system and framework)
1. Keep collecting requirements from clients and understand them.
2. Collect different designing aspects for the project and parallely, build a POC for 2 purpose: to get hands into the new Framework and also as a demo to clients. Working on POC helps in 3 ways: Improving understanding of requirement, improving framework knowledge, and playing around with code whenever bored of designing and reading tons of existing designs..
3. Once primary requirements are clear and fixed, analyse all different designs, if possible I setup meetings with senior devs, principal engineers (they help a lot when it comes to reviews on scalability and reliability of a design)
4. The above design is mostly architectural level. Once design is fixed, then I start taking each component and prepare a detailed implementation design. (Notice that whenever I am bored of designing, I spend sometime in building POC)
5. In detail design, I focus on modularity and flexibility. Anything defined should have getters and setters for example. This will help you reuse your code. Keep the interface between components in your design as generic as possible, so that in case your MySQL is change to Postgre or NoSQL, your design should be able to adapt new features..
6. Instead of building entire project, define feature targets and deliver small features.. this will help you to be in line with the requirements with minimum deviation. -

TL;DR Does MacBooks degrade faster for developers due to poor thermals?
I’m developing on a 15” MacBook Pro for work. I got it new last year. Now I’m experiencing that it crashes when punishing my CPU with my hardly CPU optimized scripts.
My thought that the poor thermals MacBooks has could be the reason. I mean, Macs are sort of known for their reliability, however I punish my CPU a lot more for many more hours, every single day than the average MacBook user.
Could the instability really be due to a fact that last gen 15” MacBook Pros have poor thermals, thus bad design for programmers, making the CPU unstable due to degradation?9 -

Half of the courses we had in our college were about electronics. Except Microprocessors and Transistors, it's not relevant.
We even had chemistry and engineering drawing. So we essentially wasted more than half of our time.
Besides languages, weren't taught anything about real world software development.
Nothing about how to work with an existing code base, version control, design patterns, system design, creating a website, debugging, functional programming, scalability, reliability.

Candidates must check application essay sample to suit their specific purpose
Students require checking any available application essay (https://wikihow.com/Write-an-Applic...) sample for its authenticity and reliability. In this regard, students should remember that maximum number of the papers available on-line, mostly free, is simply the cut and paste job, which make the task of candidates difficult in making their decision. Therefore, it is essential to check the quality of written work of such samples, while students need hunting for the example, which can suit their purpose
For example, students desiring admission to a particular course program in pathology, would need an essay sample, which would relate to the field of analytical medicine, while any written work on the subject of pathological laboratory tests can be excellent. However, finding the topic specific essays like this one would be very difficult, as students need ordering such customized essays.
Therefore, students require spending quite some time in conducting a proper research to find the reliable and trust-worthy essay writing service for getting their customized essay written within the scheduled delivery time. In addition, students should check the sources that the writer would have used for gathering the information, which is presented in the essay, to support its thesis statement.
However, the following guidelines would help students to check the available application essay sample, with regard to its essential ingredients that should be present in such essays. Nevertheless, students could also go through a good term paper help to learn the art of writing a well-defined essay, which can ensure their admission to the coveted course program.
Introduction and the essay topic
Students should check the introduction part of the sample and the method of presenting the topic in it. In addition, the writer should formulate a close link of the topic problem with the thesis statement of the essay. However, as admission officers do not expect candidates to write research papers as their admission essays, the topic question and hypothesis of the essay should be very simple and easy to understand.
However, the topic of the application essay sample should be close to the theme of the assignment. In addition, the students should check the method of presenting arguments in the main essay body, while its introduction should provide hints about them, in brief. Therefore, the sample should provide supporting details like personal examples, while addressing the essay topic.
Check essay language and structure
The language used in the available application essay sample by type of https://500wordessay.org/blog/... should be simple and vivid, while the examples accompanying the discussions should be reader-friendly and easy to understand. Students should realize that selecting officers do not expect them to use any complex terms in their admission essay, as it would give an indication of their bragging, without much reason to do so.
In addition, the essay organization should be such that the contents are transparent and free flowing, while the whole essay writing must be cohesive. Nevertheless, students should look at research paper help for learning the art of locating a good essay sample, on-line.
However, they can find more tips to check the quality of an application essay sample from custom essays.
