Hey, it's Carter, founder of Octoflock. We started Octoflock to be the simplest way to process real-time data. We are an industry-agnostic connection between real-time data sources and your data warehouse. We manage the infrastructure, recovering from failures gracefully, resource monitoring, and error correction. Octoflock is written in Go and runs on top of Kubernetes to pull from Websockets. Data can be normalized and cleaned automatically from the UI, and will notify you upon errors or abnormalities.

We’d love to hear about your experience building (or using) real-time data (or websocket systems).
Embedded high-integrity systems have traditioanlly used this kind of cycle.

It's simple to reason about and analyse. You can make assertions about worst case execution time and memory useage and you know for a fact what the order of execution is. The concurrancy on large systems like this often comes in the form of a lot of small computers talking to each other over some network/bus rather than having many systems all running on the same hardware.

Building concurrant systems with predictable real-time characteristics is hard. When you have a bunch of things that really need to happen every Nth of a second in order to fly straight, a simple approach like this is definitely preferrable. In situations like this predictability tends to be more important than raw performance (assuming you can reliably hit minimums).

That doesn't mean people don't use multi-threading in domains like this, but it's one of those things you want to keep as simple as you can and avoid where possible.
Let's say:
Something that can match LG OLED CX 77 2020 model priced $3,099.99

I'd be happy to pay at the same price without the smart features.

I absolutely can not stand Chrome. I don't like how it doesn't tie in with native services like Keychain, I don't like how it logs me into the browser when I log into a website (Google)>

Lastly Chrome is power hungry. When I need to use Chrome for work, I go through my battery almost 2 - 3 times faster than when using Safari.

I much prefer the integrated experience I get with Safari and how it feels like it fits in with the rest of the OS over Chrome which does its best to tie me into Google services.

WhatsApp New Privacy Policy: May 15 Deadline for Accepting It
There has been a lot of confusion related to the changes in the privacy policy of WhatsApp. People have started to spread rumors that WhatsApp will be deleted for those users who will not approve of the privacy policy. Finally, it has come out with a clear declaration on what will be the consequences of neglecting and not accepting its privacy policies.
It might be overly cynical, but I really think this might be the death of TikTok as 'fun.'

It won't mean the death of TT in general. This service will likely be wildly successful and prompt TT to build more platform features like it to appeal to businesses willing to pay for the attention they've managed to garner.

The story has played out the same, and I don't expect this to be much different. The corporatization of social media is a foregone conclusion at this point.

It's almost fascinating to view the changes as a kind of biological succession. It won't take long before the younger generation sees TikTok as a place invaded by the very people they were using it to escape from. And the next Facebook, Instagram, Twitter, Snapchat, etc will rise to take its place as the new cool place all the kids are hanging out.
That's kinda a shame. I have an Aukey keyboard, and mpow headphones. Both vastly exceeded my expectations. I wonder why they are begging for reviews in the first place, that's behavior I would expect from shady junk peddlers.
When you finally do make such a TV, you must sell it for more than a smart TV to be taken seriously, and only use the highest quality materials.
It’s metaphor illustrating the difference between a surgical team and a hog butchering team i.e. instead of everyone cutting away at the problem, just one person does the cutting while the others support him.
The TV isn't 1000% more entertaining though
I don't know about the US but in Europe, charging is well specified. The typical standards are Type 2 for AC charging and CCS for DC charging and the European Teslas implement those. The Superchargers are fully CCS-compatible. This was demonstrated recently, when the authentication system on one Supercharger site failed and the Superchargers would happily charge cars of any brand at no cost. The news quickly spread and there were videos of a wide variety of cars charging at the Superchargers. Actually, they seemed to be more stable than some third party charging stations. Tesla did however fix that problem on the next day :p.
I think the aim would be to show you can have a self sustaining colony in arizona. Which, probably not too hard since there are aquifers.
The controller in my industrial display accepts serial commands for control and has a fairly simple IR remote you can use as well. For customer application, we developed a simple .NET utility that they use to control approx. 240x individual displays at each facility from a single control room. Knowing that RS232 can be controlled using NodeJS these days, I'm sure more creative solutions can be developed for a personalized remote control.

Huh? The only parts restriction I've ever come across is VIN-locked special edition parts, to keep dealers from trying to build a side-business building their own special editions. Usually these are cosmetic (Land Cruiser wheels are a good example) and rather silly anyway. And, the restriction isn't "you can't get these parts," it's "you can only get these parts with a matching VIN."

In contrast, Tesla regulate all structural and HV parts. Whether this is a bad idea or not I'm not quite sure (I think the argument that HV repair is more dangerous than gasoline vehicle repair absolutely has merit), but it's a key difference.

Furthermore, while all manufacturers these days do lock down software to some degree, none do to the extent of Tesla. For example, on VW you need GeKo access for Component Protection removal, but it's $999/year and just requires a business entity. And, a few features are behind SWaP codes, but you can buy those SWaP features too, even as an independent shop. And of course, if you like you can RE the software or buy a reversed software tool suite like Abrites which will let you bypass these mechanisms without your car being remotely banned from certain functionalities.
I agree that 2-3x is more appropriate. Either way, don't you think the maintainer of Babel could easily be making more money and doing easier work (individual contributor at some large org)?

The accusations that this person is freeloading off of Babel donations seem absurd (especially when you consider who is making them). The babel maintainer could be coasting at a large engineering organization with a lot less responsibility is what I am getting at it. It's exactly what the creator did...

The accusations are unjust.

I've written a fair amount of Rust and my beginner experience was not as positive as yours. It took me a very long time to fully deal with things like the borrow checker.

My personal recommendation to anyone just writing code as a learning exercise is that they start with using Rc<> wherever a borrow checker-related issue arises. Then you can get used to the rest of Rust. Once you feel a lot more proficient you can go back and start replacing Rc<> with references (and you might find that you don't even need to in many instances anyway)

As a "serious rocket", New Shepard falls well short of Falcon 1, which made orbit 13 years ago. Blue Origin still hasn't put anything into space.

Of New Shepard development, wikipedia tells me "Prototype engine and vehicle flights began in 2006, while full-scale engine development started in the early 2010s and was complete by 2015.[5] Uncrewed flight testing of the complete New Shepard vehicle (propulsion module and space capsule) began in 2015."

Well SpaceX was founded in 2002, giving them what, a 4 year head start on New Shepard? That 4 year gap has grown much wider since then.. SpaceX got to orbit 6 years after they were founded, while Blue Origin is at 21 years and counting.

The fact that a confirmed natural infection confers immunity equal to or greater than the vaccines is well established at this point. There are something like 80 documented reinfections worldwide. For previously infected people with autoimmune issues there is miniscule upside and some potentially significant downside to getting the shots.

Donald Trump is about the last person on earth I would point to as someone whose actions and motivations should be viewed as straightforward. He's been pumping the vaccines and trying to take credit for them ever since they were approved, and his making a big show of getting the vaccine can easily be viewed in that light.

I pay mine 7% of rent - you can definitely find lower rates if you're dealing with large buildings, but I'm at 7 units total and I really like the guy.

In terms of vetting them, first thing is to check licenses - most states require them to either be a licensed real estate broker or working under one.

I prefer to work with someone who matches me in scale/style - my guy is a broker and runs his own PM service. I deal directly with him. I'd be hesitant to use a larger PM company (even if it might be a bit cheaper) at my scale, because I'm small enough that I'll be a very low priority and will have the most junior employees dealing with my properties. That can be an issue, since they're not necessarily going to have the expertise to do the long-term stuff like knowing when to get the roof inspected. When my wife moved out of her last apartment before we got married, the rep from the PM company refused to do a move-out inspection, since there was still furniture inside that could have been hiding things. Had they charged my wife for anything, we would've taken them to small claims since PMs are required by CA law to inform the tenant of their right to a move out inspection and then to perform one and provide written feedback on request. That's what happens when you're dealing with someone in their early 20s who just passed the real estate agent exam (which I have passed... it is not hard) and doesn't know what they're doing.

Also, look for companies that serve your kind of property - dealing with a property that has an HOA is different than one that doesn't. Dealing with a single family home is different than dealing with a condo. Dealing with a whole apartment building is different than dealing with a single apartment.

And lastly, references. You should be able to get a bunch of them from the PM. Try to get tenant references in addition to owner references - if the PM is ignoring or mishandling tenant issues, the owner probably doesn't know.
an alternative approach to "always buy quality tools" that has worked for me:

1. start with a cheap tool

2. use it until it breaks or until you can't tolerate its shortcomings anymore

3. use what you learned from #2 to research and purchase a high quality tool

if you never get to #2, then you didn't really need anything more than the cheap tool for this particular use case

That’s definitely unusual.
> ... websites where instead of an HTTPS loadbalancer you put a video-streaming (Mighty?) server in front of your backend. How’s that for a crazy idea?

It is not that crazy. It decreases latency, but also: disables any browser plugins (including ad-blockers!); disables alternative browsers and older versions of one and allows devs to embrace monoculture; disables any user customizations like fonts or stylesheets; disables scraping, "reader view" and most forms of automated data extraction; disables user's ability to mess with cookies.

This idea is horrible for freedom of the user and is real regression for advanced users. But it does make websites faster, and developers' work easier, so I am sure it is going to be implemented by major websites eventualy.

The only hope is that accessibility concerns will stop it. But I am not holding my breath for this.
I really hope Anker stays off this list. They always seemed to make quality products, but I can imagine they'd feel the pressure to give into shady tactics themselves if all their competitors were engaging in it.

I've ordered some things from Mpow and Aukey before and they seemed like pretty good quality as well. Not that I condone these practices at all, but I could sympathize with the argument that in a marketplace that relies on reviews and where your competitors are buying thousands of reviews, it could be almost impossible to survive without doing the same, even if your product is good.

Of course, that kind of marketplace only hurts the consumer, so I appreciate Amazon cracking down on it.

I used to work at tiktok on recommendation. While we definitely do better exploration than some places there’s still a very clear top heavy bias. Part of that is just content quality. A lot of content is worse than others for any form of media. But while we are better at showing small things than say youtube, there remain very clear tiktok stars. Even for smaller areas you will still have some creators lead in that area.
My understanding is that Mars' gravity is much too weak to maintain an atmosphere -- any gas that's produced will literally escape into space. There's also the problem of radiation due to Mars' lack of a strong magnetic field.

You could mitigate these problems by having humans live permanently underground. But that's not exactly terraforming. How can we overcome these significant hurdles to permanent human colonization of Mars?
Good point!

I was thinking of it more as the human right to a cup of tea (not meaning to belittle real human rights struggles)
The CDC wants people wearing masks in as many places as possible for as long as possible because it prolongs the sense of danger and seriousness around the pandemic.
I'm an ideas person, but I can back it up with the necessary toil to bring an idea to life. But frequently, ideas require multiple people's worth of expertise to succeed.

A healthy attitude, in my experience, is for others to workshop an idea that has a potential for a good payoff; both finding flaws and finding workarounds. This occurs with an open, collaborative culture.

An unhealthy attitude is expecting somebody with a good idea to put in 100% of the effort themselves, because that requires them to relearn/reinvent everybody else's specializations. This happens more with a rigid or competitive culture.

A survival strategy in the latter environment is to keep one's ideas secret, and (theoretically) solve future problems before anybody else knows that they'll crop up. In this way, an ideas person becomes the clinch-problem-solving-person because when the house is burning down, people are more willing to collaborate.

I am Jùnliàng, a Babel contributor since 2019. I would like to share my perspective here.

GH is a platform where people collaborate on developing softwares, so the contribution graph is engineering-biased. But operating an OSS, especially like Babel which is serving millions, is just like running a company. In a company we have different roles, none of roles is more important than the others. In Babel team, Henry spends most time on reaching out to contacts in companies, giving talks, syncing with different projects in the ecosystem, offering mentorship to junior contributors like me. None of these is visible on GH but they are vital to sustain the project, to attract both new company sponsors and contributors.

2020 is a hard time for any reasons. Before we talk about funding with team, Henry has already voluntarily pooled less money ($11k to $8k) and another long-time core contributor Brian (https://github.com/existentialism) stopped taking money. While this helped bumped up our balance, everyone taking less is a dangerous signal to an OSS: maintainers constantly fighting with financial insecurity may burn out or stop maintaining in order to recover from the mental pressure about "I am responsible for this".

I maintained small side projects like (https://github.com/JLHwung/postcss-font-family-system-ui), where the feature set is frozen and most maintenance works can be automated by bots. This is quite unlike Babel: The feature is open-ended because the language is evolving. Various edge cases should be take cared. Tradeoffs between spec compliance and output code size should be made. It is not a side project that I can dedicate part time efforts like 10hrs/week to work on.

Speaking for myself, I spend around 40hrs/week to meet my own productivity requirements. I don't think I deserve more than other paid team members because everyone has different time constraints and we don't track work time meticulously.

To avoid burn-out and not let Babel consume all my energy, I spare some time on encoding Chinese characters in Unicode, which, just like Babel, has profound impacts on ecosystem but long overlooked and underfunded. I helped submitted hundreds on characters in IRGN2487 (https://appsrv.cse.cuhk.edu.hk/~irg/irg/irg56/IRGN2487UKData...).
This looks great, thanks for building this!

The problem of how to get revenue, not just donations for something like this is an interesting one. One idea it might be worth exploring is charging colleges in order for them to be able to contact students through the site as part of their efforts to increase diversity (It would need to be opt-in for the students, to maintain their privacy). If you can keep students on the platform through college, you could do the same for employers looking to increase diversity in hiring - maybe the way to do that is encourage students to “graduate” to being volunteers on the platform when they finish high school? Then the (college) students would get the benefit of support and outreach from employers for internships during college, as well as the psychological and learning benefits of tutoring others who are a few years behind them.

I think it would also be interesting to consider making some kind of private social network for your student “alumni” - having a peer group can be super helpful for low-income students in college, so this would hopefully keep them involved with upchieve, make them more likely to succeed in college, and hopefully let you charge companies looking to recruit them.

Happy to chat about this or any other crazy ideas, contact details in my profile
This is a classic problem with successful startups. At some point, there's pressure to bring in "adult supervision", which usually means a CEO from a big company. Sometimes this works, and sometimes it makes things much worse. Microsoft and Amazon stayed with the founders for a long time. Apple famously went for an outside CEO, got into trouble, and went back to the founders. Google/Alphabet is back with the founders in charge.
I'm not sure what you're putting that in, but there's been some increasing noise in the ski boat world for electrics (eg. [1] and [2]).

Electric power density in either volume or weight is OK in a car, where once you've accelerated you're rolling on low resistance tires on a smooth surface and the weight is less important. But in a boat you're fighting the equivalent of the rocket equation where the force on your planing hull has to have more batteries to lift more batteries to go farther.

It's fine, though, for a lot of watersports uses, where you want to put out hundreds of kW for a few seconds to pop a skier up, do a set, talk to your skier without asphyxiating them in exhaust fumes and without shouting over engine noise, and then plug it back at the dock. Less fine for cruising, where you want a tank of fuel to last you whole day. You only need enough energy storage to outlast human quads and forearms, not more to outlast human bowels!
