I think Gwynne Shotwell is the rather unsung hero keeping SpaceX running correctly day by day.

"How are you so great at resolving questions about comets, when you know nothing about astronomy or orbital mechanics? Presumably because you have the right heuristics, the ones about which authorities to trust and which ones not to. But what are those right heuristics? The writers of Don’t Look Up spend 2 hours 18 minutes demonstrating that they have no idea and can’t even keep their answer consistent from one moment to the next."

Falcon 9's safety record would indicate that it is possible to have development cycles that push boundaries and maintain a high reliability production system. With regard to Musk's statements about the relationship between innovation and failure, below is a quote from the linked video about optimization in the development process, a quote that provides a more nuanced view than the pithy quote.

Then, try very hard to delete a part or process. This is actually very important. If you’re not occasionally adding things back in, you’re not deleting enough. The bias tends to be very strongly towards “Let’s add this part or process step in case we need it.” But you can basically make “in case” arguments for so many things. And for a rocket that’s trying to achieve, trying to be the first fully reusable rocket…you have to run at tight margins because if you don’t run tight margins you get nothing to orbit.

Not for low earth orbit sure, but for space travel and colonizing other planets or moons.

"Ketones are high when availability of glucose is low" - it seems the body calculates this based on the amount of insulin available, which is why you can eat nothing (and have no basal) and have a BG spike.
I would say that folding is not a consequence of SMT, but of the assignment between the VP (virtual processors) assigned to the LPAR (VM) and the processing units assigned.
So more a effect resulting from the virtualization with consequences in conjunction with SMT.
If you are rich, you’ll be fine. If you are poor, you better be lucky, or you’re fucked.
Sold both of my properties right after this started for this reason exactly. Don't regret it at all, despite the recent appreciation.

Crazy how long it took the courts to overturn that. The eviction moratorium was imposed by the CDC, keep in mind. So the CDC has authority over private rental stock now?

Visual Studio (normal one on Windows) used to be great before they packaged it with bloaty extras that slow everything down.

Vscode is great yet with each update it gets more buggy than its fixed. Let's see how many years will take Microsoft to turn Vscode into crapware too.
Don't you think this is splitting hairs? i.e. "it's OK when WE do it." How is censorship "a political topic that intersects with tech", when Tech companies do it without being compelled by law?

Your last paragraph, especially ("We could debate the merits of the specific articles") could charitably be called "weasel-wording." Yeah, we could debate the merits -- why don't we?

A reasonable addendum to the flagging process would be for the moderator to disclose:

1. Who flagged it?

2. Why did I agree?

An open question would be whether to disclose when the moderator does NOT agree.

"move fast and break things", but make sure you know the consequence of breaking it and have that pre-approved by your bosses, labeled with a large font "disclaimer" sign written in red ...
They know about performance issues don't dont want to fix or introduce performance tests? Nice.
Lol, but hey, macs are not servers, so "hahah who cares!".
If the dead company stops paying the bills, Amazon can definitely delete that.
The key corollary for "move fast and break things" is "but don't do it in production". SpaceX doesn't rapidly innovate things in production. Starship is not yet in production.
Very cool! Thanks for sharing - it’s always nice to learn about fingerprinting tricks and workarounds, from both a privacy and a “don’t unintentionally look like a bot” perspective.

What inspired the project?
Its still in alpha I hear. I don't find the assistant mode that useful either, but perhaps this is a way to develop both an assistant and search engine simultaneously?

I've been using Xcode every working day for over 12 years and on the whole it has been excellent. It definitely has some quirks but it is a feature rich workhorse.

It has integrated docs, simulators, unit/UI test functionality inc coverage reports, live UI debugging, tons of profiling tools, and I can use it to upload my apps straight to App Store Connect. Starting with XCode 13 I also have built in CI/CD. I can build, profile, test and deploy a whole app on multiple platforms from scratch with it. And its free.
I seldom use this feature, but when I do and I can't find the encoding menu, then it will be a very frustrating experience. Their logic seems to be like dialing emergency service is a rarely use feature based on telemetry, so we will just remove that. No discussion is allowed, if you challenged, then they ask you about do you have data about the use case of dialing emergency service? People can still send text to emergency service, it is fine.

And because of this post, I just checked if chromium supported encoding menu. Yep, they removed it long ago. Basically, when you need to read some very old Japanese site where their encoding is pretty non standard, you are screwed.
>I may be wrong, but isn't the reason there are so many engines on their rockets is because SpaceX isn't good at building big rocket engines?

No, that's completely wrong. There are challenges in running a bunch of engines, but it's critical to pull off for reusability. All rocket engines have a strict floor on how low it's possible to throttle them. Even 40-50% is quite hard, and I believe the Raptor is 40% though with the goal of getting somewhat lower. And for old space expendable rockets that was plenty.

But to land a rocket, you necessarily need to be dealing with bringing it down when it's nearly empty. Rockets are mostly fuel by mass, and when that's expended are very light. The thrust necessary to lift a fully fueled rocket up is massively ginormously more then would be needed for its empty weight. So if you light up at full power even for a moment it's going to fly right back up again. You want a low enough minimum thrust/weight ratio (TWR), ideally below 1 (so you can gradually descend/hover), though a rocket can get by with a bit above with a "hover slam approach" approach like the F9 uses. But it can't be that far above. But you can't just throttle a rocket engine down to 1% either. What to do?

The answer is multiple engines. Throttle is limited, but you can always turn an engine off. So if you have 10 engines which each can throttle to 50%, your effective ability to throttle from max thrust is .5/10 or 5%. With 30 engines at 40% would be .4/30 = 1.3%. Very helpful. Also means more potential redundancy for landing.

There are challenges with plumbing, harmonics, control etc which are real, so as always with rockets complex tradeoffs, and big engines have their own issues. Small engines are also easier gimble, another valuable thing for landing, and to mass manufacturer which is a whole extra aspect for SpaceX, Starship is about economics remember. But there are many solid technical reasons for the choice.
I would be prepared to bet that most people that use the more advanced functionality disable telemetry.
Thanks for the suggestion - think it might be a valid approach for us.

I saw that "...works 100% identical in production and development mode, except that we don't backup the data from development apps nearly as often" - so does this mean you don't really prevent users from using it in prod if they want to, but just warm them that this may result in loss of data and therefore is not recommended?
A list of Verizon MVNOs can be found at https://www.whistleout.com/CellPhones/Guides/verizon-mvnos. Some of these are Tracfone brands but not all. For example Comcast's Xfinity Mobile and Charter's Spectrum Mobile.

Since Verizon now owns them, they no longer consider the Tracfone brands to be MVNOs just as they have never considered Visible to be. I know in the past they have been fairly aggressive correcting publications which have referred to Visible as a MVNO.
How does one apply for this funding?

SpaceX has a really strong distinction between failing during testing and being reliable for clients. Other space players haven't figured this out.

It's not even power user friendly.

Things were so fragile, I eventually created Ansible playbooks to maintain my setup. I couldn't trust a simple point upgrade wouldn't break anything, so I had to easily replay steps to revert.

If you have to set up a whole devops infrastructure to maintain one simple home project, there's something wrong.

Got a box set of Columbo a few years ago and I'd never watched it before and like many people here are saying, each episode is almost movie length and brilliant in its own right, and the format of 'you the viewer know who did it, how can Columbo figure it out' is fantastic.

One striking thing is that technology often plays a part - technology that would have been 'clever' at the time. e.g. "The Most Crucial Game" the bad guy uses a radio to pretend he's still in a private box at a football statium. In "Fade in to Murder" the bad guy provides an alibi for himself by drugging a friend, changing the time on his watch and then watching a VCR recorded football match with him, pretending that its live. There are lots of things like that, I suppose the never ending quest for clever twists led the writers to lots of gizmos and gadgets of the time.
With more smaller engines, you have a lot more options how to control your flight. You can throttle them down individually, gimbal them etc.

The only downside is that if any of the engines explodes catastrophically, it will take the entire rocket down. This used to be a big problem in the Soviet N-1 lunar rocket, but contemporary technology can mitigate it quite a bit: with enough telemetry and computer power, you can determine that the engine is acting funny before it explodes, and you can switch it off. Losing one engine out of 30 isn't fatal.

Also, with computer modeling, a lot of the engine design and testing process takes place on screen, so many failure modes are debugged early.
The space shuttle is a human-rated launch vehicle capable of taking 7 people into orbit at a total cost of $445M per launch, or about $65M per seat. When subcontracted to Russia, the charge was about $85M per person. Crew Dragon costs about $55M per person - which is one place my 10% number comes from.

Cargo flights are different, and you should also look at total program costs from the deal with NASA. The NASA contract [1] was for ~12 launchs, minimum 20T of cargo for $1.6B. That puts the total program cost at $80,000 per kg. The space shuttle program costs were about $60,000 per kg.

But don't take my word for it, here's a quote from a NASA scientist saying their payload cost per pound went up. [2]

"My cost per pound went up with these rockets," Margasahayam told Tech Insider. "On the shuttle, it would be much less."

The article there cites per-kg costs at $10,000 on the space shuttle vs $27,000 on SpaceX. With the Dragon it came down to about $9,000 per kg, which is again about 10% below the price NASA was paying for the shuttle.

Perhaps it is easier to identify what's commonly considered un-fun than what is widely considered fun.
Technical know how, mostly. But in expected ways. Machining and engineering skills as they relate to manufacturing are different now.

I'd say company culture. They don't care about design, they don't care about performance or efficiency.

They want to sell their stuff to enterprises, no matter how inefficient their systems are in every way.

The classic Mac vs. Windows PC at its finest. Apple cares about design and thinks from actual user perspective to make life easier and enjoyable and sell beautifully designed products to make money (as a company they have a lot to be criticized of course, but that's not the topic of this thread).

Microsoft is a boring company that ONLY cares about money and enterprises.
Was it really an /8? I could believe a smaller block...
Of course you can, who is going to stop me, the life lesson police? In fact this is funnily enough a (meta?) lesson of Columbo. You can extract something out of anything. Whether it's true, a lie, fiction, non-fiction, if something is made with intent there's something to learn.

Columbo's acuity lies in his perception and his mind much more so than in the often mundane things he looks at. It's his lack of prejudice and child like curiosity that stands out and that is as true in the world of Columbo as it is in the real one.

And also maybe as a side note, most foundational texts concerning the big questions of life and underpinning most of human civilization are to large extent scripted and deliberately composed works of fiction, from the Vedas and Talmud to Shakespeare.
OpenBSD has two seed files but random number generation isn't limited to them. OpenBSD has more random sources (such as from jitter) than other systems and regularly reseeds itself. Both seed files are re-written multiple times during the boot process, each time incorporating new random. So by the time sshd starts for the very first time and creates host keys (like ssh-keygen -A), those keys should have access to good random.

The first file, /etc/random.seed is 512 bytes and is available very early as it's on the root filesystem. This file is re-written by rc(8) at every boot, halt, shutdown, and reboot.

Second, /var/db/host.random is 65536 bytes. It is also re-written by rc at every boot, halt, shutdown and reboot.

In addition to all that, rc includes:

# If bootblocks failed to give us random, try to cause some churn
(dmesg; sysctl hw.{uuid,serialno,sensors} ) >/dev/random 2>&1

I just checked my VMs and they all print unique values for dmesg, hw.uuid and hw.serialno. I can guess but I don't know how hw.uuid and hw.serialno are set.
You can always reset the device and read back the data to confirm.

Sure, that will be slow, but there is a way!
Me too, on my work PC which must be nearly 10 years old by now. I don’t get why people run an app that bundles a browser when they can run the app _in_ a browser? I must be missing something (only use teams with an external partner, and not often)
The problem is that it's impossible to guess correctly 100% of the time. You can improve the guessing algorithm as much as you want to (not that I'm saying it's useless - it's very good for regular users who only rarely encounter such issues), but you can never achieve total accuracy, which is why some sort of manual override is absolutely necessary in cases when it fails.
The Origin of Dubstep
I would generally agree, which is why I think the discourse around "misinformation" (IMO, both a legitimate concern, and a moral panic) is missing the forest for the trees.

Our failures to respond reasonably and proportionally to threats, be they ecological, medical, economic, military, even political, are all downstream of a crisis of trust, not only in institutions, but in each other. And as with broken trust in personal relationships, rebuilding that trust is non-trivial.

The Dexcom G6 is capable of alerts for rate of change, but it's about what the rate was, not what it will be. It still can be helpful.

(When looking at the app, there are "trend arrows," also, but they unfortunately are misleading in some situations. Often looking at the data points can give you a sense of your situation, though.)
Last year a couple of researchers published a paper on their approach to treat depression in otherwise-untreatable patients.

They implanted a chip in the patient's (yes, n=1) brain, which they trained to detect when the patient is going into depressing thoughts. Using Deep Brain Stimulation they terminate the signal propagation of that neural pathway.

Similar techniques have been used to treat Parkinson's.

It is indeed. It's an interesting open source project too, because its usefulness is very much inversely proportional to the time you spend using it!

Hi, do you live in the USA? I had a similar experience to you. I am considering doing a research project for grad school about patients in the USA who experienced insurance denials for CGMs.
Good thing it's not a cloud service then!
It is baffling what anybody involved was thinking here. I assume there had to be huge cost savings, because they've essentially destroyed the business. It is an absolute UI dumpster fire. I don't think I could design a worse technically functioning service if I tried.
It’s pretty unclear to me whether people use this feature much. Two possibilities seem likely to me:

1. Very few people use this feature but a few vocal users who are particularly good at navigating bugtracking bureaucracy do use it and care deeply.

2. Of all Firefox users, a small percentage speak languages for which there are many non-ascii letters and a relatively large amount of pre-Unicode content online, and of those users a small percentage read niche (eg non-facebook and old) sites with broken character encoding.

Both situations could probably lead to few uses of the menu in telemetry. Perhaps we should care more about users in the second category as they are perhaps more correlated with other things like location whereas the first set may be more uniformly distributed across the population. I think other points are also being disregarded:

- ordinary users may find the feature cryptic and confusing. Or at least undiscoverable

- dealing with character encoding and supporting the feature is painful (though the will still deal with it under the hood). Mozilla have limited resources and they (and Firefox users) want the browser to be successful and sustainable, and this means focusing resources on things that will make the browser easier to adopt and less confusing rather than chasing the short-lived gains from appeasing a small and stagnant pool of ‘power users’.
They have two there. The other one is hanging on its side in the large building next to the vertical rocket.
That's true for Japan as a whole, but Tokyo has grown since 2010.
A surprise massive bill can be worse than no solution at all, in my opinion. And if the easy path leads to massive-bill lock-in, that's also not very helpful. It's not like people didn't know how to run servers and remote storage before AWS showed up. Before AWS showed up at least your data-center costs were pretty predictable: you managed the servers yourself, so whatever the salaries summed to, that was it. It's not like poor programming ate up your years' IT budget by May.
And stealing bread is illegal for rich and poor alike!
It also depends on what /you/ setup - eg, you can certainly control some things locally and some things only through the cloud if you are using the manufacturers hub, but most things you can also buy a zwave stick and/or a zigbee stick and connect to your devices directly.

Some are a perpetual cat and mouse game though for the companies that simply must snoop your data as part of their biz model or have another reason to be terrified of you directly talking to their things.

And like any smart thing you put in your house, some things you need to block at the DNS level if they are hardwired to phone home constantly. But yes, Home Assistant and choosing the right things makes it possible to keep everything internal for sure
There certainly is a balance to giving feedback like this. It very much depends on team dynamic and the level of trust between team members.

I have experienced lower levels of trust and worsen proficiency in giving and receiving feedback described in this article since the whole WFH thing started, especially as teams at my employer change and we bring on new team members. People are a lot more sensitive, everyone collaborates less and we are accepting a lot of bad code into our projects than ever before. We had about 1/3 of a crucial team leave recently. At their exit interviews they all described how one of the reasons they left is because the code base has turned into a pile of junk and no one wants to work on it.

I recently agreed to join this team to help turn it around because I have a reputation for ensuring good engineering practices and giving feedback is a strength of mine. But boy, this environment is challenging with developers all working from home. I'm curious if this resonates with anyone else, specifically if others have similar experiences with wfh.
