We're discussing Musk's definition of "freedom of speech", not yours, mine, or the constitution's. He seems to believe you should be able to say whatever you want (on Twitter) and not get fired. This is the definition that's relevant here because his ideas about freedom of speech from his many tweets on the subject don't align with his actions as a leader at Tesla and SpaceX.
It's about how often the edge case comes up. 4 to 12 times a year, I need to drive 300 miles to visit my family. 10 to 30 times a year, I'll drive 50 to 60 miles to visit friends/family or see specialist doctors or take trip to some interesting event. But on the vast majority of days I drive less than 10 miles a day.

My edge cases come up fairly frequently and I don't really have a good fall back for them i could spend a huge amount of money or time to do the 50 mile trips via uber or transit. Or, I could own a hybrid. I could do something similar with less reliability for the 300 mile trip. Or I could own a hybrid. In both cases, i could keep an app that tells me where the charge stations are and account for any possible needed charging... or I could just own a hybrid and gas up at any random station I pass in 5 mins.

This is the problem of EVs. Yeah edge cases, but a lot of people can have their edge cases come up fairly frequently. And worse this changes over time. People like to plan for probably outcomes over the life of the vehicle. It's not strange to think you might a few hours a handful of times a year. The more people you need to transport with you the more alternative travel methods and the uncertainty of the charge network starts to matter.
I guess they're not rocket scientists.
I think maybe you just aren’t aware of the subject matter and associating it with a currently trendy word.
It's not like Pascal changes a whole lot.
I live in a downtown high rise. It’s 25 degrees outside, I have a lady friend who lives a mile away. I feel unsafe riding public transit at night here, much less her. She experiences extreme harassment walking here during the day (did it once, never again, I was on the phone with her, it was horrifying).

How do you propose she visit me without a car and available parking?

Uber would cost her more than an hour of her workday.

GP is damn right the opposition to parking is detrimental to health physical and mental as well as wealth.
He does sell a product, but that product is very optional and seems like it could be valuable for those who really like his free stuff (podcast and free newsletter)

I should have included the Ioniq in the list. It was right up there.
I know a fair number of people who have had no problem after (old) drug or DUI or violence convictions, but I usually hear about them in the context of "15 years ago I...". I don't know more current who isn't just a corp to corp contractor. I know people who have pled and haven't been sentenced, or who have had relatively recent convictions, who are working as single member LLCs for clients who know details.

If it's old or minor, I don't think I'd care as a hiring manager. It's annoying in some regulated industries since felony complicates checkbox compliance, but in "normal" industries enh.

Same in every field.

You clearly have no expertise in this field. Over.
Plugin hybrids are a thing. They're designed as a system though, so a vehicle that works as you describe would need to have more power in both systems in order to run from either one independently. And that means more weight and worse efficiency.

EV and ICE have great synergy if you use them together. EV offers amazing acceleration from zero, and relatively less amazing acceleration at highway speed. ICE has better acceleration when you're already moving. ICE efficiency is poor at low speeds, and better at high speeds, and EV is opposite. ICE can warm up the interior of the vehicle at no extra charge. If the engine is idling to warm up (itself or the occupants), might as well charge the batteries. If the battery has enough charge, it can easily start the engine when needed, so you don't need to idle unless warming is needed... And EV is always ready so you don't have the delay to go that some auto start/stop systems have.

Anyway, at least in my PHEV, it had a 'EV only' mode you can use if you charge it, that operates close to what you suggest. It does run the engine a bit here and there for 'normal operations' and will try to cycle through the gas tank over several months to make sure the gas doesn't go stale. But if it's in EV only mode, acceleration from say 40 mph to 65 mph is poor, and the battery drains quick at 65 mph vs 30 mph ish or stop and go. Significant uphill eats the battery too.

The one I drive is also very much a compromise vehicle, the extra battery for PHEV doesn't have a good place to go, so the trunk space is poor. There's probably ways to design a car to be PHEV first and find better places for the battery, but most/all? PHEVs I've seen are designed hybrid or ICE only first and then stuff extra batteries in storage areas.
Virtual CEO for a complete virtual world. What did they expect?
I agree. Although part of the challenge is that people are accustomed to jumping in their car for a roadtrip without thinking twice about their vehicle’s range. Once you’ve upgraded your lifestyle for the convenience of “not thinking about it”, well it’s hard to go back.
>The fact that any document can contain its own MD5 hash embedded in there should be hugely concerning enough.

I think that's pretty amazing, to be honest.

I don’t as many people follow Musk as closely as you think. Everyone in my circle is buying Tesla if they are buying EV. It’s the “obvious” choice because you see them everywhere; if you want an EV but don’t want to think too hard about it you get Tesla.
It's great when you have a charger capable of charging in 15 minutes.

Right now, that isn't reality for a lot of people. Chargers either aren't maintained properly, or wait times to get to a charger are horrendous.

> Especially given that most charging happens at home, saving time vs going to a gas station every week.

That's ignoring the parent post's point. The usual commute isn't what's causing range anxiety.

Some day, I'll own an EV myself, but it isn't likely to be soon.
So if you're a Java shop you pick Scala because it seems amazing until you read about real world usage/find out for yourself, and then you pick Kotlin.
> I mean, in many cases that’s grounds for dismissal and legitimately the job of a manager.

Its also probably because Elon's companies do insane shit brazenly, without even trying to hide it. Shotwell said they were fired for being involved with the letter, in writing.
Neither of you has given much hard information. No dog in the hunt here, but it sounds interesting.
great! i don't care about partisanship or politics here, anyone that took part in the activities that is still alive should be forced to testify publicly on TV about the extent of Epstein's operation as they knew it, may those same people be sentenced to death.

Normally i'm a pretty peaceful dude...but this sort of thing makes me wish vigilante justice was still a thing.
> If someone were to ask you how far your office is from the airport, I bet you’d respond with how long it takes to get there, not how many miles it is away.

To be fair, in this case, time makes way more sense. I need to know when to leave to get there in time for my flight, and I don't care about the actual distance.
I meant silly to use exploits find while performing a pentest for malicious purposes.

“Right to work” is the new speak for “at-will”
SEEKING WORK | REMOTE (Americas)

10 years of cybersecurity expertise. I can help you automate your processes and document things you didn't know you had.

I've worked with most types of security appliances, and in doing so I've noticed that many of them aren't a great fit for smaller businesses. I believe in the "holistic security" concept and working out your organization's security priorities from first principals. In other terms, I'll figure out how the bad people will try to hurt you, and we'll talk about what tools and methods your team can use to avoid that without damaging your productivity. It's generally best if we do this before the bad people do their thing, but I've done a number of remediation jobs before and I'm willing to do more. My focus is not on compliance (standards) security, but I can help you with meeting standards in addition to your (real) organizational goals.

I'm also part of a team that does physical security testing. Obviously these assignments can't be remote, we'll come to you. Our team is diverse in skillset, with backgrounds in IT, military and the regular old non-cyber security industry.

If something's got you worrying, just come talk to me. I'd also like to hear if you have some sort of unusual or interesting problem.

What will happen?

Some pharma company will vopy the antibiotic.

Farmers will give it like candy to animals and in third world countries they will dump it to rivers.

Bacterias get resistant. So the antibiotic becomes useless for humans and then ants stsrt to die off.
I fly a couple times a year but don’t own a plane. (Of course, that would be impractical)

I think the issue is largely around having to adjust the mindset to plan in advance.

For the roadtrip scenario, it might be better to just rent a vehicle for a week. For transporting large or heavy items, renting a truck beats owning one.
“Never cross a river that is on average 4 feet deep” comes to mind here, to borrow from Taleb.

Most people I know take annual or more frequent road trips for travel, sport, or to visit family in neighboring states. These aren’t edge cases, they’re normal and predictable parts of peoples lives.
MD5 has/had a well-known "media" surface - lawyers/genomics folks had heard of it. Libraries had it as an accessible function (command line utilities, even).

Sure, there are better non-cryptographic hashes, but, again the concern of lawyers and genomics folk is neither security nor efficiency - simplicity and "works most of the time" are the two metrics at stake.

If either laywers or genomics folks cared about document forgery of this nature (spoiler, they don't), they would move to something like SHA3. If they had a need for high-scalability hash algorithms (spoiler, they don't), they would switch to another faster algorithm.

This is a concept I understand security folks struggle to understand - sometimes we _just don't care_. And we never should.

Maybe, something a struggling security enthusiast could understand - a video game.

If you implement e.g. a caesar cipher, you can have fun, accessible puzzle. Implementing AES in your game as a puzzle, while much harder, fails desperately at the "accessibility" metric. In your single player game, if you want to see some "identifying hash", if you see an md5 one, that's enough. No, you should not worry about people forging documents for your ad-hoc identification system, if you don't have people attempting to forge in-game items. Maybe its even a feature that you need to forge such a hash, as a way to solve a puzzle.
I can’t work out what comfyui is about. What’s it’s purpose?
B2 has a web interface that you can use to download files.
I don’t know. I generally haven’t seen these be a problem. I think I’ve seen accidental n^2 complexity a couple of times at most and it wasn’t code written by juniors but rather just an oversight in adding nested loops somewhere they didn’t need to be. Now I have seen juniors who couldn’t figure out what was n^2 and how to fix it when given it in an interview, but slowness and big-o being related is generally rare. As you mention poorly considered sequences of network calls are more common). Additionally, the relation between the big o of a data structure and the big o of the overall algorithm solving some higher level problem tends to be more decoupled except for some very specific problem domains. I’m a systems engineer having worked in OS, embedded, mobile, and distributed systems and have seen big-O analysis of the high level code documented about 0 times (and it would have been helpful about as many).

Again, not saying it’s irrelevant and it might be highly relevant in some problem domains. But in general big-O of the common data structures should be memorized with the rest being trivia that should be accessible in the documentation for the data structure (or by looking at the implementation and doing it yourself).
Is anything negative that happens to/is said about Musk his own doing, or is everything just a ploy by external entities to bring down a great man?
Love my 38-mile summer / 31-mile winter PHEV for exactly this reason. I’ve bought maybe a dozen tanks of gas over the past two years.
Agree with everything you said.

> One thing that concerns me with making such a system is that one should be really careful when collecting people's data and preferences and then recommending based on that (thinking of YouTube recommendation slippery slopes).

The plan is for the entire recommendation system to be open source and customisable. Because it's using LLMs as opposed to traditional ML models, it can be more easily reviewed by the end user and customised with natural language prompts. You can see the repo here if you are curious: https://github.com/OpenPipe/open-recommender
B2 is great if you don't test your backups.
When making a dupe detector some decades ago, I kept the filesize outside of the hash.

No need to compute the hash until there's at least two files with the same size.
I agree with you.

I watched some students prototype a simple diplomacy type game on paper first, targeted at phones. On paper people got it, talked to each other, negotiated. On the phone, people just stared at their screens, made choices entirely in isolation, no "diplomacy" what-so-ever.
My advice: Start your own cybersecurity company. No one will hire you for any IT position. So you need to create your own. A niche that isn't being addressed is cybersecurity offerings targeted to small nonprofits. You'd make a killing.
> On-device AI excites me far more than relying on yet another cloud-based API.

Agreed. The huge leap-forward in capability already boggles my mind, the fact that I can run it _on my desktop cpu_ and have an interactive, natural-language oracle of the internet in a mere ~11GB file.

Everyone seems to be chasing the network-accessible API approach because lock-in is easy and if you're at the bleeding-edge (training) you've got the compute for running it anyway.

But now with accessible, local models my bet is on bored young hackers coming up with the best use cases and killer apps, not Microsoft.
> finding one should be like kicking down the door to a whole room of related possibilities

You actually agree with the GP, you are just being more specific about what “one working” means, and providing more criteria for what getting “closer every year” would entail.
Just ban older GA aircraft from most airports. Why do these things need to be tolerated?

I completely echo the sentiment of being frugal. (We are a competition to both retool and airplane and bootstrapped)

One of the companies we sold earlier was around leadership learning content and I was attending one shoot where the CEO of india unilever business was recollecting lessons from professor Ram Charan. one of them broadly equated inverse relationship between aspiration and resource as a determinant of entrepreneurial mindset. And they at unilever used to artificially starve resources to create such an environment for out of the box thinking. Net net there mostly exists a way to achieve things with minimum resources. And tough markets calls for such measures even more.
> SpaceX probably just wasn't aware.

They filed a Supplier's Declaration of Conformity without actually measuring unintended emissions? Seems a bit hard to believe, and rather disturbing if so. It's not like Part 15 Subpart B is in any way obscure!
It was called the Chevy Volt. GM discontinued making them because the Bolt is sooooo much cheaper to produce.

Everybody knows that hybrids are a stopgap and will go obsolete. Consequently, there is negative motivation to produce hybrids.

The problem is that nobody knows when hybrids will go obsolete. If you recommend manufacturing them and they go obsolete during your corporate political tenure, you're screwed.

Govenments need to start subsidizing charging stations just like they subsidized filling stations along interstates and turnpikes. That way we can just make the jump to pure electrics.
Pascal pointer notation was so logical. Dereferencing a pointer was just a caret to the right of the variable.

A double pointer was just two carets. And so on.

There was a struct symmetry about the whole thing. C broke that, especially with strict pointers.
Thats not at all what this says lol. Its simply some research pointing out that Starlink likely has some unintended radiation at specific frequencies. Nobody is calling for regulations or anything, no need to instantly come to Musk's defense.
This is super true. It's why programmers like writing game engines. It's relatively well defined all the parts needed so it feels like you're making lots of progress when in reality you're just re-inventing the wheel and not doing the truly hard part, the actual design and content creation. I'm super guilty of it myself.
If it is a non-issue, why raise it?
+1 on the Bolt EV. I've been riding passenger in one pretty often lately, and it seems pretty damn good for a GM econobox EV. Not overboard in the crazy vaporware/unfinished tech garbage like a Tesla, and the 200hp/3500lbs is totally adequate. Could use a bit more range, but it's enough for most peeps IMO.
And they are relatively cheap on the used market. The Volt is still awesome. I'm considering upgrading our 2017 to a 2019 (the last year they made it). But at 130,000kms ours is still getting 100km per charge in summer (70km in winter). Ours is a family car and we do less than 10% in gas mode.
> The argument is a clear strawman; it's playing down what people have genuine concerns with and focusing on the range aspect that's obviously unimportant

It’s not a strawman if suddenly it costs hundreds more to rent a car to go visit the grandparents for the holidays. That doesn’t scale either because everyone will want a long range vehicle for holiday travel, making costs for them soar and availability drop.
I feel like I know you, lol
This post really resonates with me today because I started journaling this year, and the rule I set for myself is to write (or, in my case, type) for a minimum of 5 minutes without judgement. Even if one of the sentences ends up being "I'm not sure what else to write", that's fine, because I'm just getting into the habit of taking the action step. It's been rewarding.

Your point about the journaling being to an audience of yourself makes sense. When you write on the internet, you open yourself to criticism from strangers on the internet. But, at least you took the action step of actually publishing it. That's how you get better.

This was an inspirational read. Thanks for posting and congrats on your HN success.
It is even worse for people like me, despite having a charger in my home. I almost never drive short distances, I walk everywhere locally. When I do drive, it is very long distances, and in those cases range and refill time counts for a lot. On their best days EVs have inferior range and in many conditions they have markedly inferior range. Add on top of that the lengthy recharge time (topping off a gas tank is <5 minutes) and it fundamentally changes the logistics of long distance travel in a negative way. I have nothing against the idea of EVs, they are just really inferior for many common driving patterns in the US. Not everyone does 100% of their driving in the suburbs or has the ability to charge at home.

My minimum buying criteria for an EV is simple: high ground clearance, all-wheel drive, and 650+km range with a car full of people and luggage in freezing temperatures. Trivial to buy in a gas car for not much money and essential for many people in the US.

We will know EVs have arrived when Americans in the mountain west start trading their Subarus for Teslas.
Applying admin controls to Slack is completely different than firing employees for raising concerns

For starters, firing someone introduces legitimate damage and liability for those damages if done illegally

But also, firing a group of people who are organizing seems like it will run afoul of union protection laws.

And to your first question, Musk’s social media tantrums have caused a lot of collateral damage for his companies. I believe the Tesla board also raised concerns that his Twitter meltdown had negatively impacted Tesla. It’s not hard to see how.
Aren’t they orthogonal concepts? Right to work means you can’t be forced into playing Union dues (you have a “right” to scab) and “at will” means the employer can fire anyone at any time for any reason (other than protected classes).
Then I hope your boss isn't a racist troll.
Plot twist: He's a persona created by an AI, like Adam Selene.
There's a difference between finding a collision and finding a second pre-image. While I agree you shouldn't use MD5, and absolutely don't use a signature algorithm which uses it, finding a second pre-image is harder than finding an arbitrary collision with MD5.

An "arbitrary collision" here means you can find two inputs (pre-images) which hash to the same thing. Like you ran some code and discovered that "SDFKLHKLJxchjasdfgklhjaskdhjlf9" hashed to the same thing as "klhkasdfhjkl899078790". Finding a second pre-image means you start with one message, like "ALL QUIET. REMAIN CALM." and figured out that "ATTACK AT DAWN 051928" hashes to the same MIC.

I can't believe I'm defending using MD5. But... finding second pre-images is still hard. Sasaki & Aoki say it's got a complexity of around 2^116.9 and requires 11 * 2^45 words of memory (thought 1400Tb isn't THAT outlandish these days.)

Still... statements like "finding a second pre-image is hard" don't age well and will guarantee a tractable second pre-image attack will be published tomorrow.

But... if you have a bunch of docs and you're not signing them or asking people to trust the hash of each doc, you can (reasonably) quickly de-dup by sorting by MD5 hash and then looking for dups. Which is how many people use MD5. And they continue using MD5 because multiple organizations have similar lists and if you wanted to change it, you would need to get everyone to move to a different algorithm.

But yeah... at this point we should assume someone will publish a tractable second pre-image attack "any day now" and get to work migrating from MD5 to MD5 : Next Generation. But good luck getting more than 2 people to agree to what the next preferred hash algorithm should be.
That's new to me. I thought cold only impacted peak power, not total energy.
