PoW is not required to have a blockchain. What you need is any consensus algorithm. For example you could use Proof of Stake.
I think the more interesting way to do this would be to create a border that's roughly circular to frame the giraffe, and fill that border with noise. Then do the incrementing thing, and your 12 or so bits of noise at the end will blend in better, making it harder for the average person to reverse engineer.

I'm imaging something like this, but with a giraffe instead: https://6d4be195623157e28848-7697ece4918e0a73861de0eb37d0896...

It’s pretty much the same thing - take some arbitrary data, and add some bits so that the result is prime. Not surprising from a mathematical point of view since primes are very common, but it’s a fun thing to see.

Because every node in the network must be able to verify all transactions all the way from the genesis block. In order to ensure that this is possible, everyone who keeps the history must keep the full history.
The thing about llvm ir is you get a code builder "for free" from llvm, where you're just calling functions to build your ir. However, when emitting C you have to build that yourself and take care to always emit valid code. Not sure how much difference that actually makes though.

Are you contending that those products often run unvetted code? There's a world of difference between the likelihood of these problems being exploited on a servers that aren't shared, routers, small internet devices, and IoT devices compared to shared hosting environments, end user systems (whether they be mobile or desktop) and cloud/virtual server services. Of the latter, I'm o ly aware of FreeBSD being used in any frequency for shared hosting, and even that is relatively rare. FreeBSD just doesn't have the same exploit exposure as the others. But Google compute cloud, AWS, windows, MacOS, and Linux (including Android) definitely are ripe for exploitation.
Having implemented CBOR [1], it's really only an issue for the x86, which can do unaligned reads. On most other architectures (even little-endian ones like RISC-V) it's less an issue because you will either have to copy the bytes to be aligned, or just read byte-by-byte (sorry, octet-by-octet) and shift.

Well there are several issues with Cassandra:

- it is not ACID the worst possible way

"Cassandra is not row level consistent,[21] meaning that inserts and updates into the table that affect the same row that are processed at approximately the same time may affect the non-key columns in inconsistent ways. One update may affect one column while another affects the other, resulting in sets of values within the row that were never specified or intended."

"This is true, to a point. I'm firmly convinced that AP is a better way to build distributed systems for fault tolerance, performance, and simplicity. But it's incredibly useful to be able to "opt in" to CP for pieces of the application as needed. That's what Cassandra's lightweight transactions (LWT) are for, and that's what the authors of this piece used. However! Fundamentally, mixing serializable (LWT) and non-serializable (plain UPDATE) ops will produce unpredictable results and that's what bit them here.Basically the same as if you marked half the accesses to a concurrently-updated Java variable with "synchronized" and left it off of the other half as an "optimization."Don't take shortcuts and you won't get burned."

- there are several things that needs to be tuning (like GC) that is not trivial to do

- modeling is challenging say the least, easy to create hotspots that the developers are not aware of

Can't say I know much about womens clothing, but there a wider selection of less expensive fashionable clothes.. Like H&M, which I'm sure also compromises on quality.

Obviously, women can also get highend, quality stuff. But for men it's either highend or the supermarket, there's few things in between.

In the US my experience is that high-end stuff is being VERY high-end, and low end is becoming very low end... likely as a result of incoming inequality.

Generally speaking, when a language developer adds really useful, special syntax to a language — that language users cannot define themselves — it seems like a good idea to stop, and consider whether it makes sense to restrict the usefulness of this concept to just this special case.

I.e. the Java boolean type, which can only be true or false (and not default). Could it be that there are other valuable uses of this ability, instead of using enums where you always have to handle the default case?

Can it really be the case that true/false is the only case where not having to worry about default is extremely helpful?

"Whatever the mind can conceive and believe, it can achieve"

I'm no expert programmer (Jr Rails dev), but am interested to see how difficult this is to do. Perhaps if not too difficult, I can try and help you with a prototype or point you in the right direction?

More than anything I believe in the power of vision for change which you seem to have found in your idea.
I completely agree with the sentiment. To me we are destroying society for ads and likes. We value moving homescreen backdrops more than long lasting batteries,
useless web games more than reliable medical applications,
mining crypto currencies more than curing cancer with scientific computing.
Our tools are boring and lack imagination, our hardware architectures and the way we program them are the same dead horse beaten to death.

We branched off somewhere in the 80s and forgot that there is a timeline where things just work, where they serve a purpose for the greater good and where form follows function.

Programming right now is 90% wasting everybodies time by creating stuff that nobody really needs in a way that nobody really deserves.

But it's a hole we dug ourselves.

Afterthought-

I find it telling that everybody in this thread exclaims that they love "the puzzle" or "facing themselves in times of hardship", but nobody talks about creating stuff. Programming shouldn't be a crossword puzzle that you do for it's own sake, it should be a means to reach a goal, and produce something meaningfull. And as with every means the less you have to do of it, the better.

The best line of code is the one never written.

> we cannot know the world as it is, independent of the structure, capacities, and limits of the human mind

This resonates with me. For example, I feel that even though mathematics and physics are perfect systems for describing nature and the universe, I am not convinced that mathematics is a property inherent to the universe itself as many people often say. Rather, I think there is a significant chance that these systems are tied closely to the structure and operation of the human brain.

1. Do you find this useful?
2. Is the usage simple?

Sure the US has addressed gun laws. It has maintained that firearm ownership is an individual right and the laws reflect that.
>>Does this not seem absolutely absurd to anybody else?

It does, and it's shit like this that makes me absolutely convinced that US is a 3rd world country, where people have to weight their own health vs the financial cost. There's plenty of people saying they don't want to call an ambulance because they are worried what their bill would be. That people would risk their lives and that of their new born baby because there is a financial cost associated with staying at the hospital for another day is beyond absurd, it's like bad fiction about some distant society where things have gone horribly wrong, except that this is real and calls itself the greatest country in the world.

If you get high latency on a Linux machine when doing audio stuff you probably have hardware problems or software is misconfigured. Years ago I moved everything I had under XP (Reaper+plugins) to a Wine directory, reinstalling those plugins that didn't like to be moved, and never looked back. I'm using the kxstudio repositories software (RT kernel, Wine etc). http://kxstudio.linuxaudio.org/
Latency is very low, even on old PCs such as Core Duo ones, and compatibility is very high.

The only problem I encountered with Reaper under Wine is that it needs a lot of time to buffer a very big audio track when it's being added to a project. Say I record my band on our portable recorder then I drag and drop the big sample (2-3 hours stereo 44.1khz x16bit stereo uncompressed .wav) on a Reaper track, it starts eating all PC's memory to buffer it hanging the machine for a a good minute. Once the track is added, the memory gets released and it works perfectly though, so it's not technically a bug and I have no idea if it depends on Wine or Reaper.

A few months ago I also started to use the native Linux Reaper port which is fantastic and lately got a lot more stable, but all my attempts to have Windows plugins working in parallel with it through Wine failed although they say it is possible, so although there are some interesting plugins out there, they're not remotely comparable to what is available for Windows (but that would be the case for every other native application): using Wine is still the best option if you are not just strictly recording and need external plugins. I also explored the possibility to have musical software working on a Windows VM with disconforting results so far: computing power is there, but latency is a nightmare. As of today, to me Wine still offers the best options if one needs both low latency and compatibility.

> primes are very common

Isn't it thought that they get more and more rare the further you go away from zero in the positive direction?

By the way I just realized why no negative numbers are prime and that's because -1 is a factor in all of them. Quite obvious but I just never thought about it before.

The physical area is virtually the same. They merely appear to be taken from slightly different vantage points. Both show the area where you might reasonably expect people to observe from. They are taken at the same time of day differing by a matter of 5-20 minutes.

No, Bob's misconduct would potentially be provable in court based on the trustless data ledgers in the blockchain.

Really, this example just shows one way how developers could use blockchain technology to develop applications that utilize trustless data.

Imagine this same technology applied to the transfer of human organs, rather than easily replaceable ice cream.

However, another important aspect is that currencies around the wolrd fulfill the same functions whereas when it comes to crypto - each token will represent anything that the creator intended it to be PLUS what the community uses it for (e.g. store of value). And each token will have a different 'design', different functions - from being tokens to enter the platform (e.g. Ethereuem itself) to tokens representing fractual ownership in assets (e.g. Maecenas art tokens or our RAT tokens representing a rat mascot, more about it here: https://medium.com/@katdum/what-did-i-learn-from-tokenizing-...).
So there will be coins that will be fulfilling the descirption of a currency (apart from the government requirement) but there will be only a few ones compared to the vast amount of tokens with different functions.
Reading philosophy has been an enligthining experience for me. I was no criminal, but a depressive teenager. As I read my first philosophy books---dialogues of Plato initially, then Schopenhauer, Freud, Lao Tzi, etc.---I learnt, not much from the actual informational contents of these texts as most are now outdated, but critical thinking. Through that I defeated the feeling of being abnormal, and the depressive state itself. I proceeded to answer many basic, existential questions with confidence, and to acquire a consistent, secure outlook to the life.

We suffer quite a bit because we are not able to, by default, deconstruct what the worlds does before our eyes and to us, and understand the mechanisms that govern the pheanomena. Knowing how the universe works, as far as modern science can explain it to us, and being able to think and observe objectively, are key to living a "free" life, i.e., free of lowly things like being a robber, or being too greedy or too aggressive, etc. The knowledge of the heavens does transfer to the execution of an ethical life: lest one leave himself to the command of "destiny" or dogma. I think thus, for example, astronomy must be a mandatory topic for the younger students as soon as possible, so that they are not raised with the outdated idea that something "up there" governs their life.
This doesn't seem too unlikely to me. Fighting Trump has become something that seems to override concerns about democracy or any other principle for a wide swathe of people. Supporting intelligence agency meddling in partisan politics is one of the milder, more widely normalised and expected parts of being anti-Trump today; the more extreme fringe views involve support for tactics like a literal military coup.

I wonder, if mass media existed at the time, whether this is what the Church vs Galileo affair would have looked like from the outside.

There have even been arguments that the "verdict against Galileo was rational and just" because they took into consideration "the ethical and social consequences of Galileo's teaching too."[1] This has been a major argument in the Damore debate also, that even if his entire menu was true, it was right to fire him because of the social consequences within the company.

Galileo's opposition also used less well-supported opposing theories (like geocentrism and others) to discredit his work, and on a personal front tried to shame him as a religious heretic for going against dogma and established "moral" order.

I’m curious why you think this. When last I looked, a very large percentage of medical care was urgent care; in several demographics, it was a large majority.

There are a variety of ways of measuring ‘how much’ medical care is given, which has a big impact on how things compare. Cost per capital, for example, is a fairly intuitive measurement and it skews heavily towards urgent care.
