markbnj··on Ask HN: Do any discussion boards that aren't Facebook/Reddit still exist?
This is an odd question. There are tons of active discussion boards that can be found with trivial effort. Other replies have mentioned forums for specific auto makes and models, and you'll find they get spun up quite quickly when a new model comes out, and attract a lot of traffic. I don't think anyone has mentioned Steam discussion boards yet. Heck, Facebook is a discussion board in many respects.
markbnj··on Replay-based attack on Honda and Acura vehicles
I own a 2021 Honda and it definitely shuts off after 10 mins for me.
markbnj··on Replay-based attack on Honda and Acura vehicles
Fwiw, on current Hondas the engine will only run for a set period, I believe 10 mins, unless the fob is used to reset the timer or the driver enters the cabin with the fob and presses the brake and start button.
markbnj··on The End of Social Media
Fair enough, and yeah searching for 'crocs' unsurprisingly returns a boatload of shoe results. This is a broader issue I think, in that coming up with good search terms that are likely to return the results you need is a bit of a skill.
markbnj··on The End of Social Media
>> Some time ago I tried to find information about Crocodiles, the animals. Instead, I got results about Crocs shoes and zero information about the actual crocodiles.

I just entered 'crocodile' into Google search while signed into my normal private account, and got a ton of useful information about crocodiles. Shoes were nowhere to be found in the first 30 or 40 results that I scanned. I don't know if the OP is using a different search engine that is more blatant about ads.

markbnj··on Software is eating the car
I'm not sure that the difficulty of performing a trick is related to its utility, and it doesn't really make sense to compare the usefulness of high beams and foglamps since they are indicated in completely different situations. Foglamps are mounted low and are usually yellow and meant to illuminate the road surface in heavy fog. High beams are counterproductive in fog.
markbnj··on Software is eating the car
Two months ago I sold a dead-simple Toyota truck I'd driven for 14 years and bought a new, loaded Honda. The difference in the complexity is of course astonishing. The yota didn't even have usb. You could climb into the engine compartment and sit there. The Honda has pretty much everything a modern car can have, and you can't even see empty space in the engine compartment.

I _could_ get on your "just give me simple" bandwagon. A part of me was proud of the low-tech, rusty durability of the Toyota, I admit it. Still, I'll also admit I like most of what the Honda can do. I like the phone integration and that I can toss it down on a pad and it will charge while I drive. I like that the wipers, headlights and high beams all activate when needed without input from me. I like that it remembers my seat and mirror settings and restores them when I enter the car. I like keyless entry and remote start. I like the backup camera. I like adaptive cruise control, collision mitigation braking, and lane keeping assist. I like torque vectoring all wheel drive. Heated and ventilated seats are awesome.

Of course, if I were to try to keep this car for 14 years I might regret it, I don't know. Honda makes good cars but there's a boatload of stuff to break, lol. I think I might be better advised to trade it in at five years or so, but I do like the tricks it can do.

markbnj··on The Heathkit Legacy (2013)
Heathkit was my intro to electronics in the 1960s and early 70s. My father gave me a Heathkit electronics lab that consisted of a board with a bunch of components, spring connectors, various lengths of pre-stripped and tinned wires, and a project book full of fascinating experiments that I did over and over. He also built our family color television and stereo receiver from Heathkit projects. I remember watching him work on them in his shop after dinner, soldering components into place for hours. Both of those units lasted a good long time, too.
markbnj··on San Francisco’s tech fiefdom is dying
There will always be a cohort which values living in the metropolis as opposed to just working for a company that has an address there, but clearly the growth in remote work is allowing workers in all sorts of industries to spread out somewhat and live where they would like to live. I can't help but think this will be a huge boon for smaller communities.
markbnj··on The Slander Industry
Let me get this straight: someone posts slanderous lies about another individual in order to defame them and perhaps profit from the defamation; google is exploited to drive the slander to the top of the search results; and you think any attempt to remove the slander would constitute censorship and compromise the purity of the information you have access to? Really?
markbnj··on 'World’s most powerful' tidal turbine sets sail from Dundee
That's for sure. I don't know anything about this specific application but having worked in the shipping business and in commercial fishing I can attest to the problems with marine growth and corrosion, not to mention electrolytic issues for any contacting dissimilar metals that are immersed. Presumably all this is accounted for but I have to think the maintenance requirements for a long-term floating installation like this are no less than they would be for a commercial vessel, i.e. about 10% of the "hull value" per annum at a minimum.

If you're interested in shipping I highly recommend the YouTube channel of Chief Engineer Makoi https://www.youtube.com/c/ChiefMAKOi. He has been talking about Mr. Aisha's situation for some time now. Really awesome to see that he's been relieved.
markbnj··on ParkMobile Breach Exposes License Plate Data, Mobile Numbers of 21M Users
I've used ParkMobile to pay for parking around Rutgers in New Brunswick, NJ where one of our daughters was enrolled for a time. Was recently receiving an unusual amount of SMS spam. Seems like this might be a possible explanation.
markbnj··on How fit can you get from just walking?
Guess I'll share my own story: close to seven years ago now I was nudging up against 270 pounds and had a 44 inch waist. I decided to make some changes and started walking 2 miles a night. This is less than half the distance spoken of in the OP, but in compensation the route involved several decent hills and I walked it briskly. I also did a couple of other things that I think were important: I stopped adding sugar to coffee and I stopped drinking soda and having desert every night after dinner. Over a period of around a year I dropped from 265-ish to 215-ish and shrank my waist to 36 inches. I'm still walking the two miles every night, seven nights a week. Coming out of the covid-19 year of sloth I've put about 15 pounds back on, so I am considering adding another mile or two to the routine and perhaps doing a few other exercises, but just walking those two miles a night worked wonders for me.

markbnj··on Discovering WW1 tunnel of death hidden in France for a century
As a history buff and occasional amateur explorer of ruins in the U.S. I think that if a thing that has any value is left lying about humans will loot it. The majority of people don't care much about history at all in my experience. They have their own pressing daily concerns, and one person's sacred history is another's material resource. A fortification becomes a source of building stones, an old barn yields timbers for a new floor, and relics are a source of cash. In New Jersey there is a place where archaeologists uncovered a colonial-era iron furnace and then had to re-bury it to prevent people from carting it off piece by piece.

Given all this I suspect the French will now have no choice but to excavate and inter the remains in the Winterburg tunnel. It would certainly have been better if the location had remained undisclosed, but I think that is really too much to hope for.

I've got a 486 chip if anyone is looking for one :).
markbnj··on What happens when investment firms acquire trailer parks
For what it's worth my in-laws specifically chose to buy a second home in a mobile home park. I don't know all their reasons but the low cost of the land was part of it. I've seen their "trailer" and it's quite nice, so I wouldn't necessarily assume everyone who lives in one of these places does so out of desperation or lack of choices. People have different needs and wants.
markbnj··on US Pipeline Caused Biggest Spill in Decades, We’re Just Hearing About It
Agreed. The statement also caught my eye and the only thing I could find that seems even remotely relevant is http://www.earthdrx.org/specificgravitylesser.html. This is very specific to lighter fluids injected into a subsurface ground layer below a water layer, and theorizes as to why the lighter fluid may not percolate through the heavier fluid above.
markbnj··on Take a look at Nomad before jumping on Kubernetes
We're all-in on kubernetes and cri where I work, but Nomad is cool and if we were starting out now we'd certainly take a close look at it. We use other Hashicorp tools, terraform for example, so we're already familiar with HCL (which I don't necessarily prefer over yaml or json for declarative tasks but that's another debate). Most of the simplicity argument comes from the single server/worker binary and ease of deployment on the ops side, which if you use managed k8s like GKE might not mean all that much. If you're going to implement and run your own clusters that's a bigger deal.

Looking at it from the consumer side and comparing like to like I don't feel its a _lot_ simpler. Task groups and pods, tasks and containers, config, networking, storage, it is all different on nomad but not, imo, tremendously simpler. That makes sense given the nature of the problem the systems are addressing. Over the last five years kubernetes has grown horizontally a great deal to encompass more and more enterprise features and use cases, and I feel in general this is a repeating pattern: a thing is created, it works well and becomes popular, more people use it and join the community bringing their own use cases, which drives the addition of features to the thing, which eventually gets complicated enough that people are attracted to a new thing that does largely the same stuff but hasn't had a lot of the new features added yet. Rinse and repeat.

On a somewhat unrelated note: I'm not very attracted to server-side features for tracking and manipulating versions of deployments and their history. I'm a fan of git ops, and what I want out of the server-side runtime is reliable, fast reconciliation of the infrastructure state with the release branch in my repo. If I want to roll back I would much rather revert in git and redeploy. It seems troublesome and error prone to rely on a cli command to force the server side state to a previous iteration that is not in sync with what master in the repo says should be the canonical release version. Interested in others' thoughts, but maybe its a separate topic.

markbnj··on Google admits Kubernetes container tech is too complex
"Auto industry introduces automatic transmission, admits manual transmissions were too complex." - probably actual Register headline from 1939.
markbnj··on 1977: Zork
Yeah I doubt the disks can even be read anymore.

I have Zork from Infocom in the original packaging with 5.25 floppies... wonder if it's worth anything?

I have regex101 open in a tab any time I am developing a regex :). It's an awesome tool, and I especially appreciate the mini language reference in the lower right corner of the window.
markbnj··on No support Linux hosting shutting down from hack
> Given that they shut down suddenly and you could not reach a human, it sounds more like Google Cloud ;)

On Google Cloud for over four years, with three kubernetes clusters and a few dozen VMs across three projects... and this thing you describe has never happened. Have you had a different experience with them?

markbnj··on Statement of SEC Regarding Recent Market Volatility
I don't get this. I can't imagine the professional investor class is still blindly following their shorts. They're all out by now, aren't they? If the "little guys" are making money I tend to think it's coming from other little guys.
markbnj··on Cracks are showing in Enterprise Open Source's foundations
True, but there are a lot more applications and use cases for an open-sourced redis than an open-sourced twitter. Let me try again: Twitter was built on an open source foundation, changed the way people communicate forever, and created a huge amount of liquid value. Without open source things like Twitter probably would not have come into existence. Twitter has in turn contributed a lot of important open source software back into the community. Elasticsearch or redis, by contrast, enabled many of these cool new things to exist, but by themselves those excellent software components changed very few lives. If you made redis and tossed it out in the world with a ta da! very few people would care. I always felt that open source was an explicit recognition that we care about and attach value to the big ideas that change the world, and that by making the building blocks freely available we caused more of those big ideas to come to fruition. Now that the big ideas are perhaps a little harder to find we seem to want to attach a price tag to the parts again.
markbnj··on Cracks are showing in Enterprise Open Source's foundations
> Perhaps I'm missing your point here, but as far as I know, there's nothing in the Open Source or Free Software movements that ever viewed FOSS primarily as the basis for interesting proprietary software.

Proprietary doesn't factor into it. Maybe a clearer way to put the thing I am positing: the idea behind open source is that it is interesting end user apps that have value and change the world, not the software components from which those apps are built.

markbnj··on Cracks are showing in Enterprise Open Source's foundations
> First, how can we make sure developers who build open source software are compensated for their work in a just way?

Honest question: isn't this a fundamental contradiction? If you are building a thing that by definition is given freely to anyone who wants to use it, how does compensation for that work become part of the formula? You can't be monetarily compensated for it, because you chose to give it away. There are other forms of compensation but that seems clearly not what we're talking about here. The author goes on to ask how you can build a business around open source? But isn't the answer that you can't? If its really open source then the software itself is not a business.

That, to me, seems consistent with the original idea of open source: that it was the cool things you could build with code, not the code itself, that had value. None of the iconic success stories in tech over the last decade have sold code, have they? They've built things on FOSS code that never existed before, and most of them have contributed a lot of FOSS code back. But they haven't sold databases, reverse proxies, and key/value stores, right? I've paid six-figure annual licenses to Oracle. Is that the world we're trying to preserve here?
