> I feel forcing login to Facebook is going to kill oculus adoption

I'm hoping you are right, but I feel like the average consumer is not so privacy aware and wouldn't mind using Facebook as their login. It's probably even more convenient since they already have a Facebook account and don't need to create an additional account for Oculus.
When I've seen GA used or recommended to people, it's because their use case is tracking the marketing performance of their website.

Tackling the privacy focus for GA is great, but they're a good deal of products out there that already fill that niche, not to mention the requirements of the privacy crowd usually being a venture into itself.

If you wanted to make it relatively competitive for marketing, the simplest addition would be adding labelling via regex for referrers.

i.e. - Some users want to be able to group Baidu, Google, DuckDuckGo, into a single bucket for comparison. Some users want to break them down into common market segments by country.
"https://www.baidu.com/link?url=FyYbCZqj65Vc7A4XeSNrOcQCS2qFX...

is from your live demo referrers, and makes it difficult to actually assess the amount of traffic from Baidu. Using a regex label means that users can break down traffic from Paid/Organic marketing fairly quickly, and start to build up dashboards they can use.

If you ever extended it to allow multiple labels for each hit, could re-run the regex over past data, and could build reports off it, you'd easily have a benefit over GA that would start to wean the marketing crowd off it.
>So they're not 'forced' to per se - but if they don't sell they'll lose a large part of their market. Or am I wrong?

Correct.

>you have to delete backups, can't keep them forever

Not for a file hosting service, the customer trusts you to do your job.

>If it gets destroyed, is it a backup?

Destroyed means physikal interaction, since it is not possible to make a reallife backup this is you last line of defence.

>Can your backups be accidentally destroyed?

Well if someone "accidentally" breaks into my bank opens the right tresor and "accidentally" uses a flametrower..the you are right.
This is one thing to try to find out when one applies for a job. What kind of stupid requirements are there and is this company prone to senseless prescriptions? Even if one thinks that a particular senseless prescription is not very burdensome to oneself it still indicates an inclination to senseless prescriptions. One should avoid such places when one looks for a job. And that actually is a risk that management is perhaps not very aware of. The people who have the most choice of places to work can just decide not to work for you if you like to push your employees around.
It concerns biotech.
The reason contractors and consultants have silly requirements like this placed on them is because they’re service providers, not employees. The managers are the customers in this arrangement, and customers often want silly things, like your physical presence in the office, because perhaps that just makes them feel better, and it’s fine if some silly thing makes your customer feel better.

The broader issue he’s talking about is simply the inefficiency of large organisations. There are many things that start to become much less efficient the more you scale up the size of an organisation, including risk management. This is because the feedback loops between decision and outcome starts to get much longer, the causal relationship between decision and outcome starts to become much more blurry, the distance between decision maker and impacted user gets bigger, and management starts to be comprised of less leaders and more bureaucrats.

Not only is this unavoidable, but it’s a good thing. Large businesses benefit from the economies of scale, but smaller organisations get to compete with them, because smaller organisations have the potential to be orders of magnitude more efficient than large ones. It also creates market opportunities for other B2B companies to come along and address some of their efficiency issues. I’ve done lots of consulting and contractor work, and one of the primary factors that drives demand for my services is enterprise inefficiency. Even if you put aside any consideration for how slow they are to adapt to new technology, a lot of demand for my contracts has been driven by strict corporate salary bands. The board sets the maximum rate that an engineer is allowed to be paid, and any team in the company that requires skills that the market has priced above that rate can only access them through external contractors/consultants. I’d bet the same is true for the OP, even if they don’t know it, so perhaps they shouldn’t be so quick to deride enterprise inefficiency.
>Article asserts that bitcoin transactions should be processed in a more socialist "fair" ordering, as opposed to a more capitalist style "user pays" priority based system:

You've mis-interpreted the article. The authors are saying the opposite. The paper is somewhat hard to read maybe because the 4 co-authors are from Germany so their English-as-2nd-language isn't the easiest to parse.

For the specific paper, the authors are using "fair" to label fee-based-user-pays-priority which is the conventional expectation of how Bitcoin behaves. However, they analyzed a bunch Bitcoin transactions and noticed that priority based on "user pays" doesn't always happen. They're not exactly sure why but put forth some guesses. They considered that some miners might be "altruistic" (i.e. "socialist") to consider other attributes besides fee payment but they discount that. The other guess they feel is more realistic are "transaction accelerators" that don't broadcast the same blocks to every miner. Excerpt from section 7.1:

>We hypothesize that mining pool operators might be sending a different set of transactions to each miner (or perhaps changing this set every a fixed time interval or event) to reduce the network overhead, avoiding miners to request a new task often. It is possible due to the stratum protocol.

>Stratum is a pooled mining protocol that focuses on reducing network communication between the mining pool and its miners by allowing miners to change some bytes on the coinbase transaction and consequently changing the Merkle root. Another reason is that some clients might be using services like transaction accelerators to speed up the commit time of a particular transaction. They pay the mining pool to use this service off-chain (i.e., with another cryptocurrency or via credit-cards) to, hopefully, increase the probability of their transactions get included in the next block. One example of this service is the BTC.com transaction accelerator.

Near-IR, which many of the available ToF (Kinect2, K4A, Basler/Lucid/Sony), active stereo (Realsense D4xx, Mynt, plenty more), and many some structured light (all Primesense derivatives, some older Realsense) cameras use, as well as close UV frequencies, suffers much the same issues as visible light. Farther wavelengths in shortwave IR start to have different/better properties, but the costs of cameras are just astronomical (~$20K/camera). Farther UV is also possible, but eventually we're dealing with frequencies that are actually harmful.

I do think there's a lot of open possibility in using more than the traditional visible spectrum. Using polarized sensors to remove reflections, or hyperspectral cameras to reduce noise that only appears in certain bands are good ideas. The problem is that we've got lots of cheap imagers that are really well built for visible spectra, and not a lot outside that. Small hyperspectral cameras for things like agricultural drones do exist, but they tend to work by combining multiple sensors (one for each band) which works fine for the ranges a drone operates at but not very useful at the close range indoor robots need.

Ultrasonic has a rather bad name in the field, a lot of people having used absolutely terrible robots with basically useless ultrasonic rangefinders early in their careers. In theory sound could be really useful, and there are some very nice (and very expensive) imaging sonars for underwater robotics use, but I'm not aware of any high-resolution ultrasonic sensors for land robots. One minor challenge with ultrasonic sensors in real products is ensuring that they are inaudible to people and pets - when they are almost-audible they are extremely annoying or even painful.
Even the best manager is faced with a bandwidth problem. It's impossible to collect accurately everything that the engineers are doing. And each layer of management is applying its own compression on what information they get from the levels below.

What is frustrating when having the feet on the ground (or in the code), is that we clearly see the issues on our level. But conveying that in a understandable and nuanced manner would require too much context.

IMO a good solution is to leave breathing room in the agenda and trust that the engineers will work on fixing those issues. By making them somewhat autonomous they can skip the politics and get right down to make their lives and the product a better place.

That was also a pebble bed reactor. The kind of reactor generating all of the latest hype is a molten fuel salt breeder reactor. There's a really substantial difference between the two and the MSRE was basically a mock up of the core running on Uranium fuel salt that would have been generated in a fertile Thorium blanket salt around the core and been reprocessed into the fuel salt.

Pebble bed reactors have tons of drawbacks that don't apply to most modern Thorium reactor proposals. The biggest drawbacks to proposals like e.g. LFTR is corrosion risks which were largely addressed by the MSRE ages ago, and the chemical reprocessing equipment which again is mostly a chemical engineering problem more so than a nuclear engineering one.

The US is 10% of TikTok's user base but 50% of revenue. Most of TikTok's most-followed users are American (https://en.wikipedia.org/wiki/List_of_most-followed_TikTok_a...). Canada, Australia, and New Zealand are probably another 5% of revenue. The UK may be not included because TikTok has stated that it wants to establish its global headquarters there.

There has been talk that Microsoft is interested in buying all of TikTok worldwide (TikTok isn't available in China; ByteDance has a separate, similar business there), which would be easier technically because TikTok's operations and algorithms would not need to be divided. India was TikTok's largest userbase until the recent ban; presumably a non Chinese-owned TikTok could quickly reopen there.

I'm not sure how true that is for sectors other than software/AI, but in AI most academic researcher complain that all the moonshot research (often not even commercially applicable) is now solely coming from corporate research labs e.g. Deepmind, Facebook etc., as opposed to universities. They attribute this to poaching of faculty by companies, lack of resources in universities, lack of motivation in grad students to stay in academia.
At that point, is there really a benefit of having it all on one wafer, as opposed to just using chiplets?
It seems to be very common to not understand, or misunderstand, the difference between power (watts) and energy (watt-hours). Even amongst technically-minded people who should know better.

A respected UK newspaper once printed a dramatic article claiming "20 new nuclear power plants" would be needed to power electric vehicles in the UK. This was nonsense and all based on confusing the estimated energy use of an EV fleet (in GWh) for instantaneous power (in GW).

They did publish a tiny sheepish apology several days later[1], and changed the online version of the article, but the damage was done and the claim still gets repeated today.

It is a common idiom for dealing with deterministic resource management, and takes advantage that in ML all functions are single parameter actually.

So you can partially specialize, and then the lambda gets the already allocated/opened resource, thus acting as region/arena resource allocator.

And you can combine it with currying to apply the concept to multiple kind of parameters.
As far as I can tell it’s replicated (by default - see “reduced redundancy storage”), not backed up.
Just a quick clarification. My comment wasn't clear I wanted to talk about waste from reactors specifically, but yes there is more nuclear waste if you do include all sources.

Why don't we talk about the difference between high level nuclear waste(HLW), intermediate level waste(ILW), and low level waste (LLW)?

The volume breakdown for nuclear waste is roughly
LLW 90%
ILW 7%
HLW 3%

"Radioactivity" contribution breakdown is like so.
LLW 1%
ILW 4%
HLW 95%

> This allows different observers to reasonably disagree about which came first. Basic relativity.

that happens all the time. Lets set aside the Earth being curved for a moment - I'll use real cities but these could be asteroids floating in intergalactic space at the same distance.

I'm in London, I see an event happen in London, Moscow, New York and LA all at the same time, at 12:00:00.500 UTC according to me.

London-Moscow 9ms
London-NY 66ms
London-LA 103ms

Lets imagine they are in a straight line too and all in the same reference pane.

The events actually occurred in the follow order, at the following milliseconds past 12:00:00 UTC, according to our NTP synced clocks.

LA: 397ms
NY: 434ms
Moscow: 491ms
London: 500ms

From LA's point of view they would see

LA: 397ms
NY: 471ms
London: 603ms
Moscow: 603ms

From Moscow's POV
Moscow: 491ms
London: 509ms
NY: 509ms
LA: 509ms

From NY's POV
LA: 434ms
NY: 434ms
London: 566ms
Moscow: 566ms

So LA thinks LA was first, NY was second, London and Moscow co-timed third.

NY thinks LA and NY were co-timed first, then London and Moscow co-timed third.

Moscow thinks Moscow was first, everywhere else was second.

London thinks everywhere was first

So we disagree. So what.

Now sure, if your wormholes are in different reference frames you can get confusions, but why would a wormhole with two ends fixed in the same reference frame and neither end accelerating allow passing information backwards in time?

I know relativity says there is no universal clock everyone agrees on, but isn't that only applicable for points in different reference planes (and even then you can surely adjust if you know your relative velocity to the universal point)?

Back to cosmic scales. Point A, B, C, D, all 10 light years apart, same reference frame

Point A event happens at t+0

B sees at t+10, C and t+20, D at t+30.

D also has a wormhole to A, so sees the event in the wormhole at t+0, and causes a separate event (light up a sign saying "A event just happend")

C would see that D is flagging the event at t+10, but have to wait until t+20 to see it. Why is that bad?

How would D get a signal back to A before t+0. I guess a spaceship in a different reference frame (say v=0.99c) at D could see (old fashioned looking out the window) the "event just happened" message, then use a separate wormhole to send a message to a spaceship at A travelling in the same reference frame as spaceship D. Spaceship A could then light up a message, which planet A could see, but would planet A see that before t+0 on their local clock?
Aren't all rules imaginary?

> Every time someone in the management chain has axed the proposal with some variation of "this policy can not be changed because this is our policy and thus can not be changed", possibly with a "due to security reasons" thrown in there somewhere.

That's circular, no doubt there. We've decided this rule must remain in place, because it's a rule. This decision-making process doesn't make any sense, but I still don't see the sense in calling the rule 'imaginary'.

Is the real point here that sometimes bad rules remain in place until some external event forces a change? Doesn't sound so profound.

Not sure why you think it is impossible when Epic literally did it. They hid the payment infrastructure in the version of the app that went through review, therefore it wasn't rejected during review. Then after it was approved, they enabled it it via a server side mechanism.
"and thinking obviously changes"

Sometimes it doesn't - sometimes people vehemently insist on application of policies even though what they produce is ridiculous.

At a former employer I was quoted £70K (yes seventy thousand) for internal hosting of a not particularly business critical single static HTML page that would be accessed by maybe 100 people. I actually got a breakdown and it all made sense if you applied the policies the infrastructure team had invented - it didn't matter that the result was nonsense.
