Just curious on what’s the best way to do market research for the product

This is tricky - there is no one right answer. I would start by building something that you need ("scratch your own itch" as some people say). It's much easier to build the right thing when you need that thing.

But also good to "sanity check" your instincts by checking in with people whom you respect and whom you think will understand the market better than you (which is what my parent comment is trying to get at).
I played it a bunch. It was a real fun game. I liked how easy it was to come up with and execute your own crazy heists.
Yeah — they totally butchered it.

The removed op codes are the ones essential to make cool things:

Arithmetic, string manipulation, and bit manipulation.

The remaining ones are substantially less useful... and why I’m long in ETH rather than BTC.

If a car never breaks down, then you don't need to waste time at a mechanic, either.
But, but...the data structures were all lock-free! Who cares if throughput sucked?
Gitolite/gogs/gitea should all be capable to enforce policies like what you described.

If your concern is data loss/malware, anything on the git level is going to be insufficient (but can still be useful of course, as you said)

I’d echo the suggestion of zfs snapshots replicated on a separate mirror of disks. I can recommend zrepl to set up the snapshotting/replication/pruning part. Syncoid is another popular one.
If she thinks this needs to account for other things dark matter has glommed onto, it can only be because she is confused.

It wholly suffices for it (it being GR!) to account for rotation curves, and nothing but rotation curves. It doesn't even need to account for all curves, just a bunch. The more it does, the less DM there is room in the universe for.

It will then be Dark Matter advocates' problem to explain why it exists almost nowhere except in places that needed fudging.
This seems like an interesting business-model, charge for the open source software because it is worth the money for your customers, and nobody could do the same as cheaply, and because you fly under the radar.

But assume profits are increasing and competitors arise. Then what would you do? How would you compete with them? Would you try to make the publicly distributed software less maintainable by for instance reducing the amount of documentation that comes with it?

You might have multiple versions of your source-code, some with comments and some without. You could then choose whether to distribute the version with code-comments or one without.

You might go further and apply some kind of "minifier" to your source making it harder to understand and thus modify.

As far as I understand it GPL gives rights to the users of the software but puts few if any restrictions on the provider of the software. So would it therefore make sense to distribute (only) a minified version of your source-code? That would make it easier for you to compete against your competition.
Me too. If it helps OP: https://paste.sr.ht/blob/a9c9431df20e51106c21834abc321e64c23...

Edit: oh, so looking at strace, right before it crashes, the program is looking for sox, which it apparently needs to play audio. Installing sox makes the segfault goes away.
> In Rust adding a new special-purpose background thread with some standard-library channels is 30 lines of code and I can probably even access the same logging system from the other thread.

Do you happen to have a link to code that does this? This sounds similar to a problem I have right now and I’d love to see what solution you’ve arrived at.

The gold standard's deflation was associated with pretty good results:

In any case, in a multi-currency world with low-friction electronic exchanges available, it stands to reason that deflation is less likely to be damaging, since the switching costs to more inflationary currencies are low.

Latency hiding is a a way to substantially increase throughput by queuing massive numbers of requests or tasks while waiting on expensive resources (e.g. main memory access can have latency in the hundreds of cycles for GPUs). By scheduling enough tasks or enough requests that can be dispatched in parallel (or very soon after one another), after an initial delay you may be able to process the queued requests very quickly (possibly once per clock cycle or two) providing similar overall performance to running the same set of tasks sequentially with very low latency. However, such long pipelines are very prone to stalling, especially if there are data dependencies that prevent loads from being issued early, so getting maximum performance out of code on architecture that heavily exploits latency hiding techniques can require a lot of very specific domain knowledge.

Panels tend to have one of a few common interface standards: https://www.digitalview.com/blog/lcd-panel-interfaces-a-quic...

I recently came into a pile of V-by-one panels, and discovered boards for them are significantly harder to come by than their eDP or LVDS brethren. But I've found a few on aliexpress and we're up and running:

https://www.aliexpress.com/item/32860791745.html

The nice thing about VBO is the connector is more-or-less standardized, and it's a very durable JAE series, so plugging and unplugging isn't such an issue. (Prototyping with LVDS or MIPI DSI tends to run into fatigue issues unless you're scrupulously gentle.)

Beyond the panel interface, there's also the matter of the backlight. Sometimes the backlight driver is separate, sometimes it's built into the scaler board. The connectors for these are almost always evil and you have to hope your supplier can include the cables, because you'll never find them yourself.

I would loooooove to find a source for the SDK to build the software that runs in the scaler chip. When I buy the scaler boards, they come with random firmware that the supplier isn't particularly interested in updating. Other builds of the same board support DDC/CI but don't have the backlight driver on 'em, and cost more. There's so much stuff about the firmware I'd like to change...
Omni is a completely different blockchain than BTC. That's what powers the Tether network. It's far from decentralized though. It's a cartel of exchanges that operate the network.

Colored coins were a neat idea but completely impractical in practice. Hence, why they never took off. Bitcoin script is far too limiting to build expansive applications on.

Everything that I talk about is internal to the router.

Some of us think that the architecture of big routers is plenty important. It's those routers that hold up the backbone of the Internet and a whole lot of other places.

Yes, you can build distributed routers. The supernode that I discuss is one such example. But that doesn't mean that you want to build it with a bunch of tiny home routers that you bought off the shelf at Fry's. You still want to start with fairly chunky building blocks, otherwise you end up suffering from a lot of inefficiencies just interconnecting things. Jonathan Turner calls this the 'small switch penalty'.

AR Racer – RFS Game
Improving the store of value functionality of the Ethereum base currency will drive more demand for it, which increases its market cap and thus improves Ethereum's Proof of Stake security, makes more capital available to the DeFi system, where ETH is the primary form of collateral, and allows more inflationary currency that's backed by ETH, like DAI, to be issued.

Also, most Ethereum based projects depend on ETH reserves to fund their operations, so ETH appreciation provides more resources to develop Ethereum applications.
> Developers love building developer tools, often for free. So while there is massive demand, the supply vastly outstrips it.

This is key, and plays out over and over again in different forms. There are no points for difficulty, only supply and demand. PG puts this well [1]:

> That's the essence of a startup: having brilliant people do work that's beneath them. Big companies try to hire the right person for the job.

Think Einstein designing refrigerators.

Gravitomagnetism [1] a new thing I hadn't heard of until reading this. I played with the math a while, and it seems that a fast spinning object in the lab would generate a field 2.5E-12 times that of the earth, if my math is right. A 2" trailer hitch spinning at 10,000 RPM, should generate a field of 2.5E-26 Hz

That's an incredibly small effect. I doubt it will get measured on the ground in a lab.

The Ethereum community consists of thousands of application developers, tens of thousands of ETH2 proof of stake validators (who have been operational since December), and millions of users. There's no debate in the ETH community about the shift to proof of stake. It's already half done.

What Ended Indie
What is reality?
Indeed there's always some secret sauce in finding product-market fit - but it's always specific to every product! One can only discover it by toiling hard with customers and be opened for unbias evaluation of inputs coming from all the sides. There's no guarantee that you'll discover it for your product before you run out of the inner drive to toil.

Yes, there will still need to be more charge points than there are fuel pumps but your charging won't necessarily be exclusively at DC fast chargers. It will be a mix of DC and AC charging.

For example, if you're on a road trip you might DC fast charge during the day and then slow charge overnight at a hotel so you start the day with a full battery.
> Do people in America seriously consider it an acceptable trade-off when "Binance blocks U.S. residents from its website"? This just looks like own goal after own goal.

I've been a part of many for-real security audits. This is largely incorrect scare-mongering. Separate admin workstations are symptomatic of a bad security posture and check-box security, they are absolutely not necessitated by nebulous concerns about the directory being readable.

Of course a server process which is designed to modify (among other things) group memberships needs different permissions than a user, why would that not be the case...?

If you don't like it being highly privileged, don't grant it the permissions. Or hire someone who can.
Do you think the headline is correct in labeling this as a 51% attack? The other argument would be that developers are trying to push through a contentious fork (mostly but not only contested by miners and mining pools), and mining nodes are planning to not adopt the proposed change?
The bigger issue is coordinating these threads ("workers") with threads from other processes, there is nothing on Windows and Linux to do so, then again I haven't had much experience with Grand Dispatch (OSX) to know if it's worth. Windows has new thread pool API, but even TBB or ConCRT do not use it. (though the new par-support in STL (msvc) does).
The Laws of Durability
"original" is a matter of debate. For example, which chain is the original Bitcoin: BTC or BCH? Prior to the fork, they both share the same history. The community aligned more behind BTC but surely there's a fork of the multiverse somewhere in the space-time continuum where the community rallied behind BCH and gave it more hashing power.

What’s with all of this seemingly whitewashing of history? Slava himself described why it failed. I mean as founder you have to be laser focused. Yet he was too busy trying to win over his “hot new employee” than focusing on the database.

There is an archive of his deleted tweets here where he describes it: https://gist.github.com/travisbrown/059310042193a2e143408b05...

And then there was an article that seems to be gone from the web (https://web.archive.org/web/20201130215752/https://threader....). It stands to reason this huge distraction played a role in the mismanagement of the database and why it ultimately didn’t succeed.

There are actually four spaces that can be filled by accounting for only a single pattern. Two of those are at the end instead of the beginning.

I agree it definitely feels imposing when you first look at it, but stick with it. Look for spaces that have a very small set of possibilities, and then try to map out what neighboring spaces could have for each possibility. If you really feel stuck, take a screenshot and mark it up.

I don't understand -- isn't what you are suggesting single threaded async code? That might be useful for servers, where you are mostly waiting for other things (like databases and networks), but in ithe places the point of parallel is to get all your CPUs doing useful work, and then (in my experience, happy to be shown counterexamples), coroutines aren't very useful. You just want to blast a bunch of threads (or rightly coupled processes)
> Not sure why a convicted felon away for life gets any credibility in the tech community.

Because the fact that he is a convicted felon or the duration of his sentence have nothing to do with his technical skill or ability? (Aside from the fact that his failure in opsec lead to his arrest and incarceration.) Just because someone is punished for doing something bad doesn't mean they suddenly stop having good ideas.

Another way to look at it, if you were in a room with Ross Ulbricht and he was telling you to not touch a wire because while you're standing in a puddle because the wire is electrified are you going to ignore him because he's a convict?

Think of the most terrible thing you've ever done, the thing you tell no one. Do you think that other people should instantly discount all your good ideas if they found out about the terrible thing that you've done?
There are many operations on data that are relatively slow from a CPU’s perspective — filling a cache line, page faulting, cache coherency, acquiring a lock, waiting on I/O to complete, etc. All of these add latency by stalling execution. In conventional software, when these events occur you simply stall execution, possibly triggering a context switch (which is very expensive). In many types of modern systems, these events are extremely frequent.

Latency hiding is a technique where 1) most workloads are trivially decomposed into independent components that can be executed separately and 2) you can infer or directly determine when any particular operation will stall. There are many ways to execute these high latency operations in an asynchronous and non-blocking way such that you can immediate work on some other part of the workload. The “latency-hiding” part is that the CPU is rarely stalled, always switching to a part of the workload that is immediately runnable if possible so that the CPU is never stalled and always doing real, constructive work. Latency-hiding optimizes for throughput, maximizing utilization of the CPU, but potentially increasing the latency of specific sub-operations by virtue of reordering the execution schedule to “hide” the latency of operations that would stall the processor. For many workloads, the latency of the sub-operations doesn’t matter, only the throughput of the total operation. The real advantage of latency-hiding architectures is that you can approach the theoretical IPC of the silicon in real software.

There are exotic CPU architectures explicitly designed for latency hiding, mostly used in supercomputing. Cray/Tera MTA architecture is probably the canonical example as well as the original Xeon Phi. As a class, latency-hiding CPU architectures are sometimes referred to as “barrel processors”. In the case of Cray MTA, the CPU can track 128 separate threads of execution in hardware and automatically switch to a thread that is immediately runnable at each clock cycle. Thread coordination is effectively “free”. In software, switching between logical threads of execution is much more by inference but often sees huge gains in throughput. The only caveat is that you can’t ignore tail latencies in the design — a theoretically optimal latency-hiding architecture may defer execution of an operation indefinitely.
Swift has a stable ABI at the cost of what amounts to runtime reflection, which is expensive. That doesn't really fit with the goals of Rust, I don't think.
