I am not sure who’s in agreement with that. Being technical or a manager are not genetic traits, but acquired skills. I love working with people and tech, always have. Forcing people to do either against their will wont work, indeed, but what you describe sounds like what a manager would say to justify their position of doing nothing, really. Also part of a good technical person’s skillset is self management. If you cant manage your own time then i am sorry, you are not an experienced engineer.
I think protocol churn extends well past datacenters and homa, with the need for 21st century domestic protocols to remove all of the baggage from tcp/ip completely.

TCP/IP could be offshored where the undersea fiber meets the shore and setup perimeter dataedge servers as the only TCP/IP nodes on domestic boundaries.

For a domestic protocol, it does not need to be routable and saves even more overhead (I liked the tcp joke in the comments btw).

Encapsulation over a domestic protocol would still make subscriptions to a tcp/ip service available, but IMO, domestic boundaries would be better served with a modern domestic protocol.

Hypothetically speaking, if every TLD was established on its own unique protocol in the original design, Internet 1.0 would have matured much differently. Every TLD is a .com nowadays anyways, too ambiguous to be of any use (and the .org debacle still makes me laugh. They forgot what an organization was and just blended into a .com reject. That mission statement was just toilet paper after the tug-of-war).

As it turns out, one size does not fit all with protocols. Multiprotocol networks within domestic borders without tcp/ip wouldn't change any of the benefits of a data network.
It should be expected that when you force yourself into a bad situation, and can only make bad decisions, people will observe that you made a bad decision when you inevitably do.
I already said twice that I didn't understand whatever point you were trying to make. If you "want to actually have a conversation" like you say, you could try either directly addressing my comment or at least rephrasing and expanding on your point.

You said everyone should be tolerant of everyone else's definitions. Doesn't everyone include progressive, conservatives, USA Today, Twitter, and the Babylon Bee? If so, aren't you suggesting they should all stop complaining about the definitions the other groups use?

Dear Jack,

The first time you visited my office I was excited to meet with you, the founder of two powerhouse tech companies. Our meeting exceeded my expectations, particularly when you asked me to join the Square family as a member of the Board of Directors. I was shocked but honored. In the past, I’ve been offered many board seats and turned them all down, however this time was different. With your success in the tech space and our shared vision to have an economic impact on small businesses and especially the unbanked and under-banked around the world, this was a tremendous opportunity. I proudly accepted your invitation while remaining fully committed to my mission.

As you may know, President Obama announced that the federal government would spend $7 - $12 trillion on the US infrastructure over the next 10 years. With this in mind, I launched an infrastructure fund, JLC Loop Capital Partners, to take advantage of the development opportunities nationally. Initially I thought it would take some time to raise capital, however, my team and I were fortunate that the first investor we approached invested $1 billion. Within the 1st quarter of 2016, we have over $1.3 billion in our newly formed fund that will require a significant and unwavering time commitment from me as I work to secure contracts around the country.

Out of respect for you, the other board members, and Square, I regretfully have to resign from my board position effective immediately.

You have an outstanding board and I truly believe that your businesses and products are leaving an immeasurable impact on this world. If you need me at any time, please don’t hesitate to contact me. I wish you the very best and have no doubt that you will continue to be successful.

Sincerely,

You're missing the frame size comms that then occur following this.
No, what implies the sitting around doing nothing part is the lack of anything useful being shipped for years combined with losing money for all but 2 years of their life as a public company combined with the absurd manager to engineer ratio. The cushy perks are just a cherry on top.

Nothing Twitter is doing requires the amount of people they have. So what are all of those people doing?
There was a time when out of order packets triggered congestion handling in TCP stacks which drastically reduces performance. This is where the concern comes from. I think it's a bit out dated though, I think the newer schedulers ignore out of order delivery.

I've also seen problems on some embedded stacks, but that could easily be argued that the implementation is wrong. But I've seen things like credit card terminals break due to packet reordering.
It's not that bad. What made is worse is that every browser is a little bit different and it needed to support mobile devices over time.
I regularly reframe questions when I think they're not the most interesting. It's a very common thing to do, especially in academia, that doesn't particularly indicate deception.
I agree they shouldn't be writing code, but they should probably have a fair degree of knowledge about writing code. Otherwise, how do they decide which people to hire to write the code?
They're not trying to make a universal standard. People are way too quick to dig out this xkcd.
Many tech companies have alcohol on-site for weekly informational/social events.
>I guess Musk just doesn't care about the lower income countries out there.

Is this really a priority for the lower income countries out there?
Almost no one agrees with the idea that you shouldn’t promote people into jobs they don’t want and aren’t good at? I’m as anti-MBA dictatorship as the next person, but c’mon.
Most of it.

Or conversely, a lot of it can be explained without having to resort to category theory or similarly dense terminology.

I've found that Mathematicians like to come up with the most general, tersest definitions possible, where every symbol is overloaded with layer upon layer of meaning.

You end up with language that looks like:

a = b c

For some absurd percentage of the statements. Sometimes the equal sign is an arrow, and the various symbols have superscripts and subscripts on them, but all meaning is lost unless you read the text, which then becomes an exponentially expanding set of hyperlinks to definitions that you need to unpack the definitions.

This is never useful as a method of pedagogy, yet this is about the only type of content you will ever find online in places like Wikipedia or nLab.

Any attempt to clarify with an example is resisted, because it's not "general", or "not the definition" of the concept. In the end, all practicality is erased, leaving definitions so pure that they could be referring to almost anything.
See, thats what incompetent management doesnt understand. Management is not about status or power or rising among ranks just to score points, its about who can best organise and coordinate. Power hungry managers dont belong in tech or science jobs.
Sounds very familiar to a lot of ideas that have been proposed as improvements to TCP over the years.
Even if you were right, there's nothing "obvious" about that.
> Yes that stat stood out for me too and I was wondering how to actually test this without breaking anything in the process.

dpdk has been doing just that for quite some time now. perhaps you can try that and see ?
Heres an example of an improvement to sending large files over long distances -- Tsunami protocol. It tries to get a best of both worlds to limit the detrimental effect of synchronous roundtrips in the TCP protocol for file transfers:

https://tsunami-udp.sourceforge.net/
Here's the thing about being an engineer who isn't "dead weight": you can always find a new job. To keep that 5% (or 20% or whatever the real number is) of truly productive engineers you need to make the company a place they want to work. So sure most of the people playing ping pong in your lounge aren't really worth the cost of a ping pong ball much less their salary, but your star engineers maybe like playing ping pong too, and like having someone to play with.
He didn't mean anything. He doesn't know what he's talking about. He called their PhD turned engineer turned turned CTO turned CEO a "MBA type" and was too embarrassed to ask him any technical questions.
Yeah and bacteria would build up in the reserve tank.

An inline filter of some sort could be used for particles but that would require maintenance.

There would also be soap scum build up and hair conditioner products would gunk up the works I'm sure.
> The alternative is to do what France has already done

Have a fleet with around 65% capacity factor that has correlated shutdowns right in the middle of an energy crisis? Offshore wind with no storage would be a better choice. At least you'll get _some_ energy during the lulls.

> The manufacturing chain for lithium batteries is indeed designed to fit existing lithium supply chains. Which is why we're only producing 400GWh per year. Because the lithium supply can't accommodate more production.

The supply chain for sodium ion is being built to be compatible existing lithium ion factories. Expansion of those 100s of GWh of production is already being done, and even if it wasn't, building the factory, the supply chain, and then the product takes around the same time as building NPP.

> Unlike lithium mining, which as never been done at even 2% the scale required for battery grid storage, countries have indeed succeeded in converting a mostly fossil fuel grid to nuclear power in a short amount of time

Now do the level of expansion of Uranium mining.

Don't forget you need to overbuild by a factor of 3 from average to provide peaking (otherwise you'll need those exact same 4hr batteries).

You'll need about 400,000 tonnes of enriched fuel or 3 million tonnes of natural Uranium for your first fuel load. This is over 40x the existing annual supply chain. Don't forget to build 10-40x as many centrifuges as exist. You'll probably also need to massively expand sulfuric acid production. Then (assuming you can only burn what you need..which no reactors can do on a scale of minutes) you'll burn the other 75% of known reserves in about two decades. Reprocessing will give you another five years. If you want power anywhere else there's under 6 years total (or rather you just can't because you can't load the reactors even once).

Now do the same for cadmium and silver and indium for control rods. Latest generation copper metallized solar cells use about an eightth of the silver for the same net power as a comparable NPP. Also the Zirconium for fuel rods.

> First of all, can you or can you not tell me where I can order some iron redox batteries? You write that they exist at the same price point as lithium ion, but I'm not even seeing them for sale at all let alone for the same price.

Go talk to ESS, a non-retail technology not being available at retail isn't an indicator of anything. Or Natron for some aqueous sodium ion currently being sold at pilot project prices. Or of you have enough money to jump the queue I'm sure CATL will let you put in an order for a few GWh in 2025. If you ordered a few GWh I'm sure form energy would sign a contract too -- although I'm less certain they can deliver (it seems about as probable as something like Vogtle).
Doesn't QUIC still run over TCP? I thought it was a replacement for HTTP not TCP (Edit: looks like it replaces TCP and HTTP)
I think the main thing working against any alternative is that it is easier to keep consistency at all levels, instead of trying to TCP with external connections and something else with internal.
Is it some crazy luxury to you? In my part of the world, it's the norm for employers on construction sites to provide beer for their workers. How is this any different?
> official policy change

Can you point me to the official policy?

Because last I checked, official policy wasn’t determined by media outlets quoting anonymous sources with knowledge of the situation, who may or may not have their own axes to grind.
The reporting cruft isn't overwhelmingly managers.

Someone should have told Elon this before he purchased Twitter
Yes, you are describing a hosted instance. Masto.host looks good, and the cheapest option is only $6/month. The problem with this federated approach is that the actual federation features can become pretty expensive. Hosting is cheap but if you have thousands of followers from different instances federation processes will become very expensive.
> The stdlib gives you all that you need

Url with variables routing? Csrf generation? Session loading? Forms processing? Templating? ORM? Assets pipeline integration?

If you're doing a very simple api, maybe stdlib will do. But for actual interactive webapp, it's not even close with what is normally used from web frameworks.

At my previous startup, more than 50% were good for nothing. they did not even know about indexes. As soon as i grasped their stupidity i ran away as fast i could.
This is particularly interesting as it could become a competitor to Tiktok.
I wish my house had conduit. To date I've never seen (much less lived in) a house with condiuit.

I live in a split level. The company I hired flat out refused to do a cat6 drop to my upstairs office, after spending nearly 40 minutes getting wire up a single story.

Because to expand the whole expression, such as the Einstein field equations, would fills many lines or pages.
You still have to address the argument he makes that the net effect on risk of keeping the lidar was in fact negative. You're just gainsaying it. That's not a contribution to any discussion.
Even McDonalds managers can flip burgers. You cannot manage a system unless you are at least partially involved in its operation. Managers should not be writing code all the time, but they should have a basic understanding of what the people under them are doing, otherwise they are completely dependent on other people to make decisions for them (in the best case, in the worst case they ignore everybody else and use their gut instinct).
it’s been not even an entire business day, I am not surprised when the narrative has been “oh no Elon Musk is going to remove all censorship on Twitter!” that people started posting garbage trying to test this exact theory, let’s give it some time to actually play out, this “death spiral” stuff just sounds like more fake news
> ”There is no one sensor that will do it. Full stop.”

Yet somehow, humans can drive cars with just a pair of optical sensors (mounted on a swivelling gimbal, of sorts).

In theory, a sufficiently capable AI should be able to drive a car at least as well as a human can using the same input: vision.
Nothing new here. Also, what makes someone who raised CEOs and a doctor special?

It's new to me. I'm glad to have read the article and the results suggest that it could work. I will try it with my own kids.

3/3 successful adults is a pretty good rate. I'll take it.
Don’t the hyperscaled cloud providers run totally segmented networks? What’s stopping them from using something proprietary internally and just exposing TCP at the end for termination of client connections?
Seems unlikely based on the evidence so far.

https://www.yahoo.com/entertainment/n-word-jumps-500-elon-20...
That’s one way to read it, but in my own experience the “do one thing really well” approach can yield far better results. Meaning, if vision is truly sufficient and you do it really well rather than a bunch of sensors “okay”, that may actually be safer overall. You might get far more focused and practical results from your efforts.

I’m not saying this is definitely true, and at the moment we probably can’t verify it either. I’m just “steel manning” his case, as Lex loves to say.

I think you’re probably correct that the business aspect was a significant factor, but perhaps it wasn’t everything.
The German situation is pretty illustrative of what would have happened to anyone stupid enough to try and build more power plants in Western Europe - nuclear stations would have been shut down, fossil fuels have been staring down the barrel of the burgeoning Green movement for at least 20 years and are somewhere close to being hit with legislation designed to make them unprofitable.

Renewable haven't been cost-effective (or technically feasible in some cases, renewabled seem to have been a warning sign for incoming grid instability so far) and all the alternatives have been blocked by politics. I don't know about Europe's environmental legislation but it would be no surprise to discover even most renewable plays were facing legislative challenges too due to the area they take up.

For a market solution to work somebody has to be allowed build something and let it run for 20-50 years to reclaim the capital costs and make a profit. Speaking as someone who would quite have liked to be investing in energy plays about 5-8 years ago when the problem started to become apparent, the legislative environment in the west is too fraught to risk it. We weren't going to start doing anything useful until a crisis happened to get some political cover for the unpopular energy sources. Here we are, so now maybe something will get done.
I'm not sure how the Elon experiment will go but surely the star engineers would be easier to retain if they were just absorbing the salary of the unproductive ones - and maybe some of that extra money went to more fun games and non-tech assistants who also like ping pong.

I don't have that much faith that it is that easy to always identify the slack or that it will be enough to make Twitter profitable, but it also seems a bit uncontroversial to say a lot of these companies having hiring patterns of a growth company in a low-interest rate environment even though their core product is relatively stable.
“Go read the docs” is not helpful! I tried that 8 years ago based on HN sentiment about C# and my experience with the Microsoft docs was that they are very detailed but the level of detail makes it difficult to quickly pick up what it’s like to actually use one of their thingies. I walked into the docs for Entity Framework, spent 6 hours trying to get Visual Studio and their suggested development database set up, then gave up and went back to Rails which took 1 apt-get command and 2 Ruby commands.
Nope, UDP.
Elon Musk shows what being Chief Twit is all about across weird weekend
QUIC runs over UDP, and provides streams and encryption. HTTP/3 is designed to take advantage of QUIC streams (replacing HTTP/2 streams which were problematic due to TCP head of line blocking).

The RFCs are a bit elaborate so folks interested might want to look at this instead[1], which has one of the RFC authors explaining the basics of QUIC and HTTP/3.

[1] https://www.youtube.com/watch?v=cdb7M37o9sU
Don't forget HN, which was started by noted venture capitalist, Paul Graham.
Twitter as an organization was honestly just incompetent. They also bought (in 2015) and then killed Periscope in late 2020 / early 2021... exactly as the world had started to embrace live video streaming as conferences and concerts started to capitulate and go fully online.
How would this go as a Django replacement? I still use Django for new projects, but find that I end up just putting a GraphQL API on top of the Django ORM. At face value, Ent seems to tick both those boxes, but with the efficiency of a compiled language.
I don't know when the word "cruft" started being applied to people, but I don't like it and think it should be prohibited.
The sensors also detect obstacles on the side of the car where there's no lighting. Every problem has some sort of solution, but removing the ultrasonic sensors on the Tesla is going to result in poorer obstacle detection performance. Sure, if they add 360 lighting and more cameras they can make up for that.

EDIT: Also I'm not quite positive why the image is so dark when I reverse at night. But it still is. The slope and surface of the driveway might have something to do with that... Still I wouldn't trust that camera. The ultrasonic sensors otoh seem to do a pretty good job. That's just my experience.

EDIT2: I love the Tesla btw. The ultrasonic sensors seem to work pretty reliably, they're pretty much their own system, the argument about complexity doesn't really seem to hold water and on the face of it the cameras won't easily replace them...
Must be wonderful having everyone in the continent of asia having a charged phone and cell reception in every restaurant. Us Americans are not so lucky.
Within a DC/cloud provider network. This isn’t about protocols you’d see traversing the public internet until the cloud providers see value in a protocol and start to push it out through IETF (eg see QUIC which was done by a company that owned both the browser and the data center). If there’s a “small” SW improvement that lets you use your HW 10x more efficiently that’s totally worth it given the end of scaling. You either invest in SW or pay for custom ASIC development. You’re not getting a free lunch anymore by just waiting a few years and getting that 10x gain for “free”.
Sure, but I don’t want to have two crappy looking walls in my house with a good looking third one.

Of course if I do something enough I can get good at it, the point of hiring someone is because I am not going to do it enough to get good at it.
Blackstone, Emerson Electric Strike $14B Buyout Deal
Other publishers, substack, etc. Why would anyone actually need to be on twitter? so they can break up their insight into 280 character bites and post them in 30 post-long threads that only other twitter users will read and eventually be re-digested into something most people will consume? Vine users didn't go anywhere for the longest time, most of them outgrew it by the time TikTok came around. Twitter was a fun experiment but it seems like it's been on its way out. Seems like just about anything that Elon is going to want to do it will result in deflating whatever is left.
If a person is being accused, they offended the accuser in some way.
So... basically another reinvention of UDP? I'm not entirely sure what "dataceter computing" is supposed to mean, given that a datacenter can be hosting machines for a very wide array of applications with very different network requirements.
