high availability systems can counter this and if properly implemented you could share certain workloads with both the primary and HA systems; basically anything which doesn't change data.

the its memory and storage would be a boon to dynamic indexing and common table expressions.

maybe this new technology will bring single level storage as IBM has employed on some machines to the public. Where all storage is treated as one resource and only the machine knows the difference.
Does is support allocating memory from HugePages? I couldn't find anything but it should be easy to add for *nix systems as it is already using mmap to request memory from the kernel.
Fortunately, Musk isn't involved too deeply with the Hyperloop bubble.
Blockchain-based, so pure bitcoin-style blockchain implementation isn't necessary. It probably wouldn't be that big of an obstacle adding a trimming mechanism by, for example, maintaining a group of sub-chains.

To limit the granularity of data being stored, it would only be used at authentication endpoints, to create a private session. Once you've identified yourself as reputable with a OTP that doesn't reveal anything about your actual internal ID, you can transfer secrets and further authentication is not necessary.

The system would employ paranoid homomorphic encryption [0] and a fuzzy API. Hardly a worthwhile vector for analysis compared to the standard MitM attacks applied today by state agencies and ISPs.

I took a look at the thread I think you're referring to, and both those comments and their upvotes are by established users with no signs of fakery that either we or our software could pick up on.

What you observed is probably a different phenomenon: early comments in a thread often start off negative, and only later do other users show up to post positively—their motivation being to balance things out. Often the positive comments to get the most upvotes in the end, but the whole process takes a while to play out. If you've ever run across a thread where the top comment says, "I can't believe how negative this thread is!" and proceeds to make a positive case with great fervor, this dynamic is probably why.
It wouldn't type-check, since `object` is expected to be a noun and not a verb. :)

True, education is to help realize one’s full potential. It’s not about credentials.
These aren't clients.

An analogy:
Many in the tech industry are happy to offer advice to random people at the start of their careers. But the onus is on the person looking for advice to make it convenient for other person.

If you received an email that said someone was looking for advice on some tech topic you were familiar with, but in order to see the details of the request and respond you have to create an account and log on to this unfamiliar website, how would you respond? I'd delete it and move on with my life. I'm happy to help, but I'm not a circus animal and I'm not going to jump through hoops for free on behalf of random people that I don't know.
We use NXP/Kinetis chips (Cortex M0+) and have been relatively happy with them from a cost and hassle point of view. When developing we use SWD with a kinetis dev board as the programmer hooked up to the target MCU. We have had strange issues with the MSB bricking things when updating the bootloaders but thankfully they're cheap enough to replace.

Considering that J. F. Queeny[1] founded Monsanto, that seems like a strange choice for a covert shill account. While I don't read much about other issues you may be referring to, being a farmer[2], I end up coming across the GMO and pesticide topic fairly often and I've noticed it tends to attract a lot of misinformation about agriculture. I expect, in many cases, these accounts follow these interest groups because they are easy targets to make fun of. Bullies perhaps, but unsurprisingly the internet has them just like the real world.

Starting with a beefy ARM chip! Try Arduino. If you are not familiar with micro controllers you might as well stick to something that is made for beginners. Plus as you get more advanced you can always use the raw AVR chip without the added Arduino bootloader.
That's not an "untreated lawn", that's a garbage dump; I don't think anyone is defending that.
"Whenever my deepest beliefs and my desire to get out of work both point in the same direction, from here till the grave there’s not a force in the world that can turn me the opposite way."

That's only half the equation. The other half is the complexity of the design along with its assurance activities. It's why the security and separation kernels with user-mode VMM's either had no or few flaws in pentesting. Whereas, VMware's techniques take a pile of complexity, are built with less assurance (see parent comment), and process malicious inputs in privileged modes.

Definitely designed and assured to be shattered. I'd like to see what results they get on mCertiKOS or Muen.
Why ‘Network Effects’ are so important to trivago, and its users
I don't think you can expect a daily practice to have "an equivalent effect" to a 60-day retreat. I know there are 10-day retreats for vipassana meditation just about everywhere in the world (probably for many other types of meditation too), though I've never been to one (scares the hell out of me to be honest, must be so incredibly hard - both mentally and physically).

I recently started meditating for 20-30 minutes at a time, once or twice a day, and the eerie calmness that settles in when I'm done (for the "good" sessions) is a great feeling. I can only imagine what 10 and 60 days can do.
1. You can't topicalise the subject of a subordinate clause. 2. Only plain form is valid for verbs in a subordinate clause. (maybe the particle "kara" could be seen as an exception here)
It probably depends on what your subreddits are. For me, it's Science, Space, Askscience, ELI5, and Aww.

By no means! We invited gus_massa to repost it. This is part of our ongoing experiments in recovering good stories that fell through the cracks the first time round—described at https://news.ycombinator.com/item?id=11662380 and many other posts linked from there.

Also, it's fine to repost a story if it's good for HN and hasn't had attention yet. Otherwise too many great submissions would languish unseen. This is important enough to be in HN's FAQ: https://news.ycombinator.com/newsfaq.html.
Without getting into all the details about what Berkshire is and what their methodologies are, the author merely wants to be nothing more than a "conglomerate" of tech/internet businesses, and was emphasizing his ability to close fast(er).

I think we can all agree thats about as similar as it gets to Berkshire Hathaway, and what the author is doing is not really that unique or similar.

I view the article as nothing more than a way to get press and hope to try and improve the author's deal flow in case anyone who reads the article is interested in selling their business, and if I had to guess the author got at least a few leads from it.

The cost profile for data structures is different in Go, though, since it tries to stack allocate very aggressively. GHC, like Java and many other classical GC'd languages, tends toward heap allocation.
Right. And you may not mind if 'the government' helps them out, but the people who fund 'the government' might.
Well, many of us are ready today for the new era, writing software differently: not optimizing for memory, throwing out the window ACID databases in favor of quickly hacked together in-memory ones, not knowing any disk-based algorithms and data structures, etc.

Funny part is that when I see now the article I read this

I enjoyed Moonwalking with Einstein, but I felt that it was more story than technique.

I found [Unlimited Memory](https://www.amazon.com/Unlimited-Memory-Advanced-Strategies-...) a nice follow-up to the former.

Not surprising. I've grown increasingly tired of reddit over the last few months, but I haven't found an adequate alternative. Any suggestions? What sites do you commonly visit?

Maybe this is my own bias showing, but whenever I read a Microsoft article on reddit, my shilling senses start tingling. I've seen a few confirmed examples, although luckily they usually end up getting banned.
It is a little extra upfront work, but I found it valuable to support a diversity of Lua VMs in Javascript because little impedance mismatches can really derail a project. Being able to switch from one to the other can isolate bugs, compare perf, memory footprint, or different interop schemes. There is literally no way to know at the beginning of a project whether any one runtime will be sufficient.

This was a pretty good overview. I get asked this same question a lot because I have been working with microprocessors for decades and I have used many different ones from the old 8051 to Microchip, Arm and even FPGA embedded. The way I usually start is I ask this "will you need an OS like Linux ?" (there are a bunch of follow on questions on that issue to decide that.

If the answer is yes then that steers you to a much bigger and more expensive chip, usually and increases the complexity significantly. For beginners who need an OS for their project, I steer them to the RPI simply because there is just a ton of resources on the web to help them along. There are other really good boards but I steer them to an off the shelf solution like that and the RPI seems to be really well supported.

If you don't need Linux or RTOS or similar then that narrows it to a lower end simpler solution. For beginners I almost always steer them to the Arduino even though I rarely use it myself but for the same reason, tons of support on the web and you can, over time move to C or C++ on it as you advance your skills.

I am not a big super fan of those platforms I personally have my own dev system using my own boards and system that I have evolved over the years to be able to get designs done very fast. But I just think those are good starting points for a beginner.

That's a result of having the marketing department as the ones who interact with the public. Pretty much every industry has this problem.

To get at the truth you have to find some enthusiast website and find someone there who has done enough digging to find the real technical information and specs.

Speaking of LED TVs, the next one is QDLED TVs where again it is still an LCD TV but the backlight is now improved with Quantum Dots. Confused the heck out of the public who are looking/waiting for a true Quantum Dot display.

Good advice! Obviously the best way to deal with negative feelings is to invalidate their existence by making them verboten and immoral thoughtcrimes, and then burying them waaaay down deep where hopefully no one notices them.

One starts meditation due to past life patterns and inclinations. Then as you keep increasing the effort, it becomes enjoyable. The purpose of meditation is towards self growth and rest of things are side effects.
You played it well. Especially with that last name. Folks are bound to get alarmed and fact-check the source.
I see. I think an indicator like "[repost]" might cut down on the number of times you'd have to explain it. :)

And it's still a bad title given the content.
Many of us have always made the distinction between cache lines and system memory. While this will probably be a welcome improvement it's not like all of your latency problems magically disappear.
We've had __very__ different experiences with Kratom, then. I was an active Kratom user for 2 years and was very addicted to it. Tolerance, cravings, nodding, respiratory depression, histamine response, constipation, the whole nine yards.

I was also in your shoes and told myself the same things for a long time. I had quit a few times, for long periods of time, and told myself it wasn't that bad. But each time I quit, withdrawals got worse. It won't be a mild cold-like feeling forever.

If Kratom use isn't negatively impacting your life, your dose isn't escalating and it works for you, then I'm genuinely glad that you've found something to manage your pain.

My mom has been on low doses of hydrocodone for degenerative disk disease for decades now, that works for her as well.

However, both are opioids and they carry the same risks all opioids do: opioid addiction. It would be unfair to those who are opioid and Kratom naive to pretend that addiction and all the fun facets of opioid abuse are not something inherent to Kratom. I bought into the "Kratom is safe and non-addictive" sales pitch as a teenager and suffered immensely for my naivety.
On the other hand a hash function that works well in all scenarios that constitute a theoretically sound use of a cryptographic hash function is infinitely harder to misuse.
My uncle had an old construction truck that was so jerry-rigged it was hilarious.

It was a diesel truck, but the glow plug igniter (or heater, whatever you call it) had gone out, so it was wired to a couple of toggle switches, so you had to flip one switch, wait like a minute or two, then flip a second switch, wait some more, then flip them off, then start up. They were in some kind of pull out tray (probably an old ash tray or the like) from the dash, and the original preheater would still turn on the light on the dash, but not actually heat the plugs, so it was a built in theft deterrent, since you couldn't actually start that way.

Then at some point, someone either ran over his keys or dropped them in a cement pour (I don't remember anymore), but he had to move the truck for some reason, so he busted the ignition cylinder, so he used a stubby screw driver he kept in the cup holder to start it.

The tailgate was kept up by two chunks of rebar slid through holes in the side of the truck into the tailgate. The bed of the truck was rebuilt out of recycled lumber and plywood from demolition work. Grill was rebuilt out of metal mesh that broke off one of his backhoes I think. That truck was a hell of a sight. Wish I had a picture of it.
What would be a good way to start meditating? Nothing too intense - just to dip a toe in.
You can rent Amazon time and create an md5 collision for less money than people spend going to a movie. Restating the issue as "a perfect hash is perfect" may be correct in a limited sense, but it is also highly misleading.

64 bits of ideal security is about half the industry accepted security strength in bits for a hash function.
C Is Not Turing Complete
Is there a good teardown you know of online of a modern transponder-based system? I did some quick digging and came up empty.

The reason I'm curious is that every time I've looked inside a consumer-grade electronic lock, all of the "security" is in the part that's physically accessible to the user, and then there's just a pair of wires that goes to a relay or an I/O pin (+ground) in the main control system. i.e. it's generally trivial to just figure out what needs to be done with those two wires, and forget looking at the innards of the security mechanism entirely.

Caveat: I have only examined a handful of such devices, not conducted an extensive survey.

In this case, what I'm imagining is that since the car half of the transponder pair needs to be near the ignition switch[1], there's a decent chance that it's a complete module with maybe 3-4 pins connecting it to the rest of the car - power, ground, and either "key detected" pin or relay power.

Obviously it would be safer to have the module simply route signals between the ECU and the key, so that bypassing the lockout would require tampering with the ECU, but my limited experience described above makes me think there's a non-zero probability that at least some manufacturers went with the self-contained module approach.

[1] In at least some configurations. For cars where the transponder works anywhere near the vehicle, this would not be the case.

That's a different concern. HN's culture has always been informal and implicit. That has upsides and downsides, but it's the way HN is and I'm loth to mess with it.

People invoke 'disclosure', 'transparency', etc. as if these were unmitigated benefits, but when you delve into a complex system like HN they turn out to be tradeoffs. On HN the culture is not to spell everything out. That doesn't have to do with hiding anything; the information is all out there. It has to do with respecting users' intelligence, liking minimalism, liking users to have to work just a little, and so on.

The downside of this approach is not that it obscures business interests—just think how excited the community would be to hit on something like that were we ever so dumb as to hide it!—but that it makes things harder for newcomers.

To some extent, that change has already happen.

The RAM is no longer fast: unless cached, it takes around 150 CPU cycles to access the RAM.

The RAM is no longer byte addressable. It’s closer to a block device now, the block size being 16 bytes for dual-channel DDR, 32 bytes for quad channel.

Too bad many computer scientists who write books about those algorithms prefer to view RAM in an old-fashioned way, as fast and byte-addressable.
Couple of thoughts after skimming the article. Consider weighing the importance of being able to upgrade or change uC. Don't choose a controller made by only one manufacturer (unless there is a level of certainty or confidence in their continued production/support and profitability). It would be unfortunate for example, if you used an atmega microcontroller and they went out of business, or changed their strategy and abandoned a platform, requiring you to switch to an alternative and rewrite some or all of your code. Having a codebase that can be made to run on different platforms easily would be ideal.

If there is a good chance, after a small order, you realize from feedback you are missing some crucial features and need to make changes, changes which require more it's higher or more precise clock, or whatever, make sure that the jump to the next size chip doesn't abandon or make a drastic jump in price or available volume. If you plan to manufacturer your product for a long time, ensure that you are confident in the availability of quantities at similar price for however long you expect to require it. Always be wary of jumping on board anything brand new. The Intel Edison/Curie for example based on the Quark ended up having an unfixable segfault, and was virtually abandoned shortly after it's release.

I don't know. I feel like instead of reducing memory tiers Optane will only add another layer in the stack. It is still 10x slower than DRAM, which sounds quite significant. Besides, I'm not sure if persistence is really the most important aspect of storage anyways, especially with modern-day always-on clustered systems.
> I don't really follow. If they are being charitable because of their faith, why separate the two?

Let me rephrase it: if being a christian requires you to be a good samaritan - by all means be a good samaritan. Charity is a good thing. But if you want to come across as doing someone a favor altruistically - don't preach.
No, I'm saying it doesn't. Your subreddits are much more focused, especially AskScience but not so much for ELI5 and Aww, and that's good. But they are still comprised of comments sections with opinions, questions and discussions that are put forward by other redditors that frequent other subreddits. They are part of that reddit culture where subreddits are not impenetrable silos.

Even if your only subreddit was AskScience with its heavily moderated comments section, you would only be less affected - not completely immune. That is the nature of culture.

If all things are made of matter and energy and matter and energy are limited, wealth is therefore limited.

You are correct, this is a fundamental truth of reality. If the root of all things is limited, everything that extends from it is limited.

In fact thanks to entropy one can say wealth is not only limited, but tends towards zero.
