It is possible, but you need to carve your own path. If you do the full startup grind, you won't have time. If you run your kids through the grind of various after school activities and classes, you won't have the time. But if you think carefully about what you really need, the project needs, and the kids need... you can still meet all the needs.

Set aside time for all of the above. When it is time to spend time with kids, really spend time with them instead of chauffeuring them around to have other people spend time with them. Do things with your family, and then sit down and focus on the project.

I'm not saying it will be easy. It will be harder on all fronts, and it probably is not the answer for most people. But it can be done.
Thanks for correcting! For a moment I started wondering if I exposed any confidential info here, phew!

I didn't say they were cavemen, but they were much closer to a conglomeration than a unified nation with a central government.

> E.g. just knowing some inputs and outputs of the secret model allows you to train your own classifier which behaves similarly enough to let you find perceptual hash collisions.

This seems highly unlikely. You could train a model to find those exact known hashes, but I highly doubt you could get it to accurately find any other unknown hash.

> You'd have to keep all of the following secret: the model, all its inputs, all its outputs.

These are all, in fact, secret.
For users who are fine with the single-host scope, this looks great. Definitely easier than working with systemd+$CI, if you don't need it (and for all the flame it gets, systemd is very powerful if you just spend the time to get into it, but then again if you don't need it you don't)

I could also see this being great for a personal lab/playground server. Or for learning/workshops/hackathons. Super easy to get people running from 0.

If I ever run a class or workshop that has some server-side aspect to it, I'll keep this in mind for sure.

If anyone wants a visual breakdown of the Zettelkasten method, I have created two popular videos on YouTube

I generally agree and don't know how well this holds up, but reading this article when I was around 20 really broke me out of some entitlement and helped me start working on myself. I think it made me view things less selfishly and think about other people's perspectives more. So I do think it works for the question asked here

What you can’t say by the owner of this website. Really helped me understand my own reluctance on posting about certain topics or why my friends shied away from discussing certain things.

My principles on this are:

Recycle and reduce your energy use at home.

Reuse, repurpose and repair everything that just requires some effort or to learn a new skill.

Buy less plastics and vote with your wallet.

Use public transport (big one here which America seems reluctant to adopt)

Focus your effort on 90% changes that make the 90% impact for the 10% time, rather than wasting time searching for the 10% that costs the 90% of time and effort.

Be the change you want to see. Back groups who aren't being controversial and getting famous for shouting at idiots and back the companies developing new useful tech to turn a profit based on the above.

Nothing changes people's minds better than clear action and benefit. It's louder and better than hundreds of hours of arguing.

So. Yes. My principles are intact. My money and foot are behind them.
And yes, with popularists in charge who will avoid talking about China except to cover their own failings yes, we're all doomed.

Really interesting conversation about the nature of happiness. For a lot of my life I was convinced that if I achieved my goals then I would become happy - "if I get into this uni, get this grade, get this job, etc...".

Then when I started working I couldn't work out why career success wasn't translating into feeling better. In hindsight it's obvious that getting paid more money doesn't automatically make you happy, but it was only after reading this article that it really clicked for me.
>> Maybe? It seems to me the overheads of establishing a fab process anywhere near the incumbents are astronomical.

It depends which parts are in short supply. A lot of automotive parts are still on 20+ year old nodes. 90nm to 130 or even 180nm. I would guess those are not the parts experiencing shortages though. So that leaves the fancy stuff. Bummer if a car can't be built because the infotainment SoC can't be obtained because it's competing for production with crypto mining GPUs.

Ask HN: What is a fair price for a CTO and 4 SW engineers?
SITUATION:
2 non-tech founders founded startup “digital trading platform”. The two non-tech founders agreed with a tech company that tech company builds the prototype and develops/maintains the trading platform for four years for startup. Tech company invoiced salaries for devs working on the platform. Tech company has 2 offices - one in Eastern Europe and one in Western Europe. Startup sales team is headquartered in Western Europe.

In return for this tech company got 10% of shares of the startup pre-funding. The five engineers working on the platform are employees of the tech company. The CTO of the tech company acts as the fulltime CTO of the startup.

The startup got seed funding at a 15 Mio USD evaluation leaving the 2 non-tech founders with 51% of shares and the tech company with 7.5%. Startup is ramen profitable now with a revenue of 0.5 Mio USD in the first half of 2021. Expected growth of revenue +50% in 2nd half to 0.75 Mio USD in H2.
Contract between tech company and startup is expiring. Startup wants to insource the CTO and 4 engineers. Also the tech company will offer managerial help by opening a new office, hiring devs and hire an administrator/manager. The new startups tech office will be in Eastern Europe while the startup operates in Western Europe.

QUESTION:
What does the community think is a fair price for moving the CTO and 4 engineers from a tech company to the startup and offering managerial help for 2 more years? Looking for indications in % of shares or cash.

That makes no sense. I wonder what they mean by "fake" chips? Are they simply not placing the chip on the board, or are they using a footprint compatible different chip (unlikely), or are they completely redesigning the board with another chip which has much better availability? (most likely)
> Vehicle assumptions: 200 000 km lifetime mileage

I was under the impression decent quality ICE vehicles are proven to last at least 320k km these days, and can easily last 15+ years.

Have electric vehicles even been in use long enough to have sufficient data to compare?
And here I was picturing a 4-axis machine...
The opposite is true - the manufacturing process is responsible for an average of 7-10 tonnes of CO2, while the same vehicle over its lifetime will emit more than 50 tonnes from the exhaust.

Moreover manufacturers have been reducing their carbon footprint lately. As an example VW reports that 70% of the energy the use in plants is provided by renewable sources.

That being said while emissions rules have been getting more stringent over the years, they're increasingly being followed through introducing EVs, not improvements in engine efficiency.

The AP story leads with the same wrongly arrested man, Michael Williams, but more broadly covers ShotSpotter's history and evidential failures.

> AP’s investigation found the system can miss live gunfire right under its microphones, or misclassify the sounds of fireworks or cars backfiring as gunshots. Forensic reports prepared by ShotSpotter’s employees have been used in court to improperly claim that a defendant shot at police, or provide questionable counts of the number of shots allegedly fired by defendants. Judges in a number of cases have thrown out the evidence.
This is brilliant tbh. Finally something for the developers who are more than responsible for moving the needle in the Crypto space!
One big advantage of low inventories is you do not have to fix or trash lots of parts if they were made out of spec. In the case of chips the odds are they are all good. It is just the cost of ownership but not the cost of refitting.
Nothing in this article makes any sense. You simply cannot use MAP_SHARED by default because then it will wreak havoc the moment anyone uses fork() (for anything other than to immediately exec). And I fail to see absolutely any reason why MAP_SHARED vs MAP_PRIVATE would alter the performance characteristics of multi-threading within the same process, since altought the multiple threads are technically forks/clones, they will all share the same VM space irregardles of whether you used MAP_PRIVATE or MAP_SHARED. And neither MAP_SHARED nor MAP_PRIVATE will alter the way entries in the TLB are prepopulated or not, which is going to be at the choice of the processor itself (after at all, it is a _cache_).

So can someone please explain? Maybe what he actually wants is madvise or hugetlbfs ?

There's an online beer recipe calculator (Javascript required) that can also be used for mead:

https://www.brewersfriend.com/homebrew/recipe/calculator

It calculates based on volume of the combined ingredients. I assume dissolving 1 pint of honey in 9 pints of water will result in less than 10 pints of total volume. I don't know exactly how much, but guessing 9.5 pints total, and using raw honey and raisins as the fermentables, I get 11% ABV with the high attenuation D47 yeast, and 8.7% with the low attenuation S-04.

Caramelization will reduce the fermentability of the honey, but I am not sure by how much. My guess is that it's a small effect.
Pitching this as a remote collaboration tool for business seems dangerously close to infringing on VMware's Horizon trademark (for VDI/app streaming).
The tone of GP is poor, but yes, the paint is really important if you want your car to last more than 5 years, especially if you live near the sea. And if you only take your car out on weekend and summers and can not put your car in a garage, a poor paint job will cost you even more.
Not sure you are missing anything. It sounds like a curated and personal miniweb.
I looked for a simple non-electronic car recently to buy, and found out that the government has mandated numerous safety systems requiring electronics like backup cameras, no seatbelt alarms, blind spot monitoring, lane assist etc, and in the upcoming infrastructure bill there is a rider to add breathalyzers to every new car made in America. (ref below)

Is there an officially designated cost/reduced risk ratio that policy makers can go by to determine if a regulation is worth while?

Is a regulation that costs 1 billion dollars to save 10 lives at 100 million a life considered worthwhile?

Is a regulation that costs 1 billion dollars to save 1 million lives at a cost of 1000 a life worthwhile?

Is there even an officially designated cost per life saved for new safety regulations?

If not it seems like a slippery slope, and the government can never overreach as long as it can justify the regulation by saying it saves a single life.

This has nothing to do with K&R or whatever new C standard there is. You're talking trash.

The rules around UB can be annoying, but I don't think this is a recent development, either. Probably compiler optimizations are to blame for some of this. For actual practice and pedestrian code, obscure UB bugs have little relevance.

Food for thought: C compilers are free to insert runtime checks to abort when UB occurs.
Oof. The author has my sympathy.

That's a big opportunity in itself.
I personally look at this method (and others) as means to help keeping track of discoveries and knowledge in general. I believe that it is useful for all knowledge workers, but especially for academics & content creators.
A far better way to reduce energy consumption is to not move mass in the first place.

Not building new cars certainly helps with that goal (since older working ICE cars do not junked anyway, they just go to someone else).
I find it curious that somebody so invested in recreating a medieval mead does not put in the extra effort of procuring long pepper and grains of paradise---those are certainly spices always present in my spice box.

I have never made mead myself however. Are the spices of so little consequence to the final flavour?
Exactly! Curation is underrated.
Maybe this is a dumb question, but does anyone still produce cars without chips? It's possible, and in the current environment it seems like it would be a major competitive advantage-- and might be more reliable in general.
Linux user, 100% LibreOffice, no choice & no complaints. But it is funny how MS office just always seems to have the edge.

Honestly this is one of the areas where I think a government sponsorship program to encourage open formats and the tools to work with them would be good. MS Office is one of the great productivity tools of the 21st century. It is unbelievable how much has been done with it. But the document locking will be long term harmful.

LibreOffice is competing with a software leviathan here. There aren't many beasts bigger than Office.

Supply and demand change is what increases or decreases costs. If demand don't adapt, there will be inflation to force it to adapt :)
Several paragraphs don't make sense to me:

>Our biometric datasets are sized at 1 GiB for easier file management as we could turn on transparent huge pages, if required. So it is guaranteed that mmap is being used under the hood by std::vector, so why was there TLB misses in the first place? That’s because the MAP_PRIVATE flag instructs the kernel to turn off VM_SHARED flag when creating the mapping in the kernel. This causes TLB to be cold and populate it only on demand, via page faults. As long as this translation is small, there’s no overhead. However as the memory pressure increases with concurrency, the kernel has to fight hard to populate TLB.

There is MAP_POPULATE flag to populate the mapping eagerly without waiting for page faults. I'm not sure what MAP_SHARED has to do with that.

> That aside, the reasoning behind glibc allocator’s use of mmap with MAP_PRIVATE|MAP_ANONYMOUS as defaults, is privacy and anonymity. Which makes sense, because we do not want other processes to peak into the memory region of our process. That would be a security nightmare. But I’m not sure I agree on this for inter-thread design. Threads inherently share the same process space and thus the heap. MAP_PRIVATE gets a copy-on-write mapping for performance reasons (may be). MAP_ANONYMOUS will ensure the mapping is initialized to zero. So the performance optimization is wasted away. However this doesn’t make sense for user-space data structures std::vector or malloc for that matter (FWIW, malloc, although a function, has it’s own internal data structure under the hood). No one is going to throw away a memory region after allocation without writing something into it, after all, why else will they allocate in the first place? As the size of memory being requested is large, it makes sense to use MAP_SHARED|MAP_ANONYMOUS as the default in glibc.

CoW is for separate processes, not just for any tasks. A different thread in the same process writing to a page won't trigger a copy. You don't need to pass MAP_SHARED to mmap to share memory between threads, the arguments to the clone(2) syscall which created the thread already made sure that you share the memory.

What I really suspect happened is that they didn't call std::vector::reserve at the start, so there was a lot of overhead when resizing (allocating new memory, copying the content, freeing the old memory) of std::vector, and when they moved to calling mmap directly, they effectively reserved memory at the start, as would happen if they called std::vector::reserve. Unfortunately the post doesn't contain enough details to really be sure about that.

> The problem I've always had with that story is that most people are struggling just to live on what they make.

FIRE obviously isn’t meant for someone trying to live in an expensive city on a $15/hr wage. However, there really are many career paths that readily allow the math. You’re obviously going to struggle to make it work if your goal is to work for a non-profit in Seattle or San Francisco, but it’s entirely within reach if you choose to work for an average tech company in an average city. It’s also trivial to make the math work out if you’re able to get a FAANG job anywhere and keep your lifestyle in check.

> Saving 50% of your income when you are trying to make rent is a pipe dream.

Depends entirely on your lifestyle and relationship situation. Many of us easily achieved FIRE savings rates by simply getting married to another professional, choosing to keep expenses within the limits of one person’s income, and putting 100% of the other person’s income into savings. Instant 50% savings rate, and it’s not even difficult to be honest. As a bonus, it was easy to transition to having kids and a stay-at-home spouse because we already lived on one income.

Obviously doesn’t work for everyone in every situation, but it’s not correct to say it’s a pipe dream or that it can’t work. It’s a choice that requires choosing lifestyle and career directions to match, but everything is a tradeoff.

The thing is, once there is a capability to search customer device without a warrant, why would you want to limit it only to CSAM? For example, this would be a great way to catch drug users, dealers (someone taking photo of using or their stash / stock), illegal weapon holders, tax evaders (someone posing with wads of cash while being poor on paper) and so on. Then you have countries with strong anti LGBT laws and they would certainly want to prosecute these groups. It's madness.
And it’s the same with our healthcare system and hospitals. Because they are run as businesses, hospitals are finely tuned to be mostly full most of the time. When COVID fills up 30% of your beds, it quickly overwhelms the system and it crumbles. This is why healthcare needs to be publicly owned, because robustness is necessarily inefficient, and inefficient is incompatible with capitalism.
FWIW Traefik is pretty easy to get running and configured based on container tags, which you cam set in compose files.
