A number of Linux kernel developers have been working with a subset of the Usenix FAST (File systems and Storage Technologies) community. We hold a Linux FAST workshop after the FAST conference for the past few years.

A few years back, some of the researchers (professors and graduate students) claimed they were interested in more testing and possibly taking some of their work (Betrfs[1], specifically), and productionalizing it. In response, I spent a lot of time with kvm-xfstests[2] and gce-xfstests[3][4] testing infrastructure, cleaning them, making them work in a turn-key fashion, and providing lots of documentation.

Not a single researcher has used this code, despite the fact that I made it so easy that even a professor could use it. :-)

The problem is that trying to test and productionalize research code takes time away from the primary output of Academia, which is (a) graduating Ph.D. students, and (b) writing more papers, lest the professors perish. (Especially for those professors who have not yet received tenure.) So while academics might claim that they are interested in testing and trying to get their fruits of the research into production code, the reality is that the Darwinian nature of life in academia very much militates against this aspiration becoming a reality.

It turns out that writing a new file system really isn't that hard. It's taking the file system, testing it, finding all of the edge cases, optimizing it, making it scale to 32+ CPU's, and other such tasks to turn it into a production-ready system which takes a long time. If you take a look at how long it's taken for btrfs to become stable it's a good example of that fact. Sun worked on ZFS for seven years before they started talking about it externally, and then it was probably another 3 years before system administrators started trusting it with their production systems.
Hey there, I'm the PM for Google Cloud Bigtable; if you want to talk about your experiences with Bigtable, I'd love to hear what your use case was, what your experience was, and your thoughts on how we can make Bigtable better for you. Feel free to follow me on Twitter (see my profile) and we can chat over DM if you wish.

If we chat and decide that Bigtable is appropriate for your use case, maybe you'd be willing to give it another shot? :-)

My company is in the online form builder space and usage of our MySQL RDS instances are nearing the limit of what is offered. I looked into moving certain high-volume/high-traffic data models to DynamoDB and realized we could not because each record is limited to a measly (for our needs) 400kb.

Which, depending on toxicity, is exactly appropriate.

You're arguing that there are no options, but that's clearly not correct.
I used to like facebook until it wanted to know where I was and what I was doing at all times. It's just creepy. A goldmine for stalkers and other criminals.
Interesting. It seems their pledge is structured to not do anything until an exit occurs. It's worth reaching out to them though.
Is it still compliant to the EcmaScript spec? Whats the latest spec it is compliant to? And how fast is it now compared to V8, etc...
The article forgets a very important detail:

> A single partition can hold approximately 10 GB of data, and can support a maximum of 3,000 read capacity units or 1,000 write capacity units.

DynamoDb will also split your data if you provision more then 3000 reads or 1000 writes. And the caveat is that it will not join back the shards if you later reduce the throughput back down. Instead, each shard will just get even less throughput then you might believe.
Oops, past the edit window.
*diluting you out.
He was hyperbolic but there most definitely is a ton of pressure to use Facebook and other forms of social media, especially if you are young. In some cases, people perceive the absence of a Facebook account as a red flag and even a sign of weirdness, or as an outright lie (similar to giving a fake phone number).

>People don't need lots of friends. They don't need 100s of possibly useful people on a website they have to maintain and update in order to "fit in".

I can guarantee that if you have the gregarious personality type that suits this type of lifestyle, having a large network of acquaintances that are conveniently accessible in a single location can indeed improve the quality of your life in a significant way. This is especially true for people who travel a lot or those who are in a university setting. It's not so much about social capital or social climbing but rather the simple availability of making plans and doing fun things with other people that would not happen without the specific dynamics made possible by Facebook.
You can always use the Internet Archive.

Right. The flag and the Republic.

Individually and collectively perhaps, but not only the Republic.
"how long is the subsequent startup?"

It depends. Fission is complex. Factors include reactor design, fuel age, xenon accumulation, which parts of the RPS tripped, whatever axles the resident NRC inspector(s) wrap themselves around... those are few I can think of as a layman.

"Do they have any sort of fast recovery procedure?"

While operators do strive to minimize outage there is no general "fast recovery" procedure. There is a startup procedure and that's what you follow. If everything is optimal then 12-ish hours to begin the restart, several hours thereafter to become critical, then a relatively slow process of pulling rods until full power is achieved. "Hot xenon" startups are something you study and practice in a simulator.

The military has other prerogatives and naval reactors see rapid and frequent transients. Naval reactors are built (at great expense) to do this. They're also smaller than civilian power reactors; a 165 MWe naval reactor being thought "large" whereas a 600 MWe civilian power reactor is on the small side.
Haha, I actually bought my house through Redfin while working there. My place was new construction and I felt I learned so much about real estate that I probably didn't need an agent :P

Which part of Seattle did you buy in? Was it somewhere hot like cap hill or Fremon/Ballard?

Were your agents well reviewed or new? I suspect they don't let loose the rookies in the more competitive areas.

> can you offset capital gains against income tax in the US?

You can offset charitable donations against income tax. The personal capital gains is avoided by transferring shares directly, without selling. (The charity typically then pays the capital gains via unrelated business income tax.)

> Alternatively, have you tried selling part of your stake to the new investors in the round, at a discount?

Unfortunately, no. I tried :(

Yes, I absolutely agree that good URLs are extremely useful, although personally I don't really like the long-string-of-text pattern, especially if it isn't actually significant. A short identifier is useful when sharing them offline: "HN article 14723409" or "YouTube video AQcSFsQyct8" or "forum thread 5705591"

For a blog, news, or other chronological content, I'd like to see a timestamp of some form. If it's rigidly hierarchical content, then a hierarchy (of which I should be able to remove 'subdirectories' to see the parent content) makes sense. Otherwise flat IDs are OK too.

Too bad browser developers seem to love hiding or mutilating them...
Judge rules Utah law banning undercover farm filming is unconstitutional
So was the Internet, broadly speaking. Same for a lot of technology we rely upon; the question is: what changed it from a one-shot proof-of-concept into a product?
Those two in Philadelphia did, because the ruling wasn't applied retroactively. The dissenting judge argued that it should have been. But there's nothing in the opinion about immunity for future violations.
You could, but that seems like a transformation of the program itself, not a feature of the type system.
We're working on a decentralized dispute resolution mechanism to address that. You could add it into your smart contract, which would call our contract that has voting pools that make decisions when a dispute arises.
Scale API (S16) Is Hiring ML Engineers, Sales, and BizOps
I agree that makes sense in order to prioritise your career at that company. If we look at the bigger picture though, many people reach their later stages in life without having met a partner they can share their life with. It's not easy find, and IMO orders of magnitude harder than finding a new job.

To me, if I were in that position I would ignore the basic ground rules and see where it goes. Take a chance on love and if it doesn't work out then go find another job.
It’s partly just coincidence that dynamically typed languages tend to have less expressive type systems. You could run any typechecker at runtime if you wanted. There’s no reason you couldn’t have a Python-like language where the “list” type dynamically keeps track of the types of its elements, function types keep track of the types of their inputs and outputs, and so on, to give you more precise & useful dynamic type errors. That would let you do some interesting things like creating a type from runtime data, such as a database schema.

It’s just that historically people have found it markedly more useful to have that information available statically, because it lets you prove things about your code that hold “for all” cases (universals), not just “for some” that are executed (existentials). And static information can be used for optimisations because of those guarantees—if you have proof, you don’t need a fallback.
we don't know the exact phrasing, but considering she "called the data scientist out on her transphobic survey" does imply she indirectly insulted the data scientist
Sort of, you can always find someone to write you an offer for a flat fee.
This article, like Turnbull, is incorrectly equating cost with price. Emissions are a cost. Price + emissions = cost. Renewables have been beating coal on cost for quite a while, only now they can start to win on price.

FYI: 129 MWh would be about 1300 42U-style racks for batteries alone.

Source: there's a guy in socal (Jehu Garcia) building a reclaimed peaker 1 MWh pack in about 10 racks from used batteries and equipment (50 kW 480VAC inverter) on the cheap in order to store energy off-peak (plus possibly charge using solar) and use it at peak supplemented by grid power. This is how manufacturing and other heavy industry / large electrical consumers can save money right now in US day-of-use billed grid systems.

Absolutely true, and also a problem.

The fact of the matter is unskilled people are always going to be designing websites. This is OK!

However, it does mean that we should require them to do as little as possible so they have the best chance of getting it right. Asking them to design a second UI right from the start on top of the first HTML/JS one -- and then telling them never to change it(!) -- is a little much.

Instead of URLs, websites should have UUIDs to identify each resource. They should also have metadata describing what that resource is. The metadata (eg "articles/urls-are-uis") should be able to change without breaking links to the resource. Browsers should be intelligent enough so that when you hover over a link you see the metadata, not the UUID.

(This has one downside which if if you link to thing X and the UUID is later changed to point to thing Y, it may look like you linked to something you didn't mean to. This can be trivially fixed by including a "what the metadata was when I made the link" field in links along with the UUID)

EDIT: I'm actually not set on UUIDs specifically, they're a little long. Any random, non-meaningful identifier is fine.

Really I'm just saying that points 2 & 3 of the article are so good we should have made them the default (and perhaps only) option from the start.

I think that's still an open problem. You could render a few random tiles from a few frames to build some confidence in the result. You could also build a reputation system, also running on ethereum, to establish who is trustworthy.

Author here; well, PDFBox is good for simple text stripping. If I wanted to print all the text on the PDF, that would be very straightforward and not much code. However, the PDF chart here is in essence a representation of structured data. I wanted to get the content in that format so that I could both serialize to JSON plus have an SDK to boot.
Agreed entirely, I do wonder what kind of internal constraints led Amazon to have these limits. Maybe in the future they'll go away, as so many other seemingly arbitrary limits do.
Batteries are used in lieu of pumped energy storage for several purposes:

- emergency use: it's much faster than even the fastest pump sets which can switch over in seconds

- load smoothing to avoid spooling up/down expensive peakers too much

- daily energy arbitrage by downstream / middle consumers to buy off peak and use at peak in time-of-use billed electrical services

- store solar energy for night use

129 MWh is enough for a medium-sized town or charging several hundred Teslas.

Really though, the focus shouldn't be on huge, central systems. The savings and grid resilience is realized with many few MWh systems spread to local substation-level. This has the potential to smooth out the load to be more/less constant and makes large-scale demand more predictable.
Bulk of commission actually covers prospecting. This is how the Redfin model works. It saves the agents time by funneling customers to them through the website :)
Here is the problem with ethereum business model. All new token created by ethereum are whitelable tokens. Each ico token brings new investors to own ethereum boosting its price. These new whitelable tokens are the. Exchanged for ethereum to provide funding. Each new project raises funds and lists it's token on an exchange. This boosts the value of the white lable token at a multiple of the amount raises in ethereum. Now companies need to spend money on there projects have to sell ethereum to fund there projects. This selling of ether raised by ico is at a multiple of the original amount raises in ether from new investors introduced to ico investing. This means mass e inflation on value will collapse as up funded projects sell their ether for operating funds. Can anyone explain how this voodoo economics can work for investors as a whole?
I admittedly only have been in Seattle once, but it didn't feel very friendly for people without cars (I don't drive myself, and it was a pain). It's better than average, but average is not a very high bar.

Is it really a minority of people who have cars there? Even in NYC, while a lot of people don't have cars, I'm not sure it's the minority.

Regardless of all that, if you build up without car infrastructure, you need to up public transportation to keep up. If you do then there's no problem. Is that happening in Seattle? In Boston/Cambridge people are also asking for parking minimums to be done with, but the public transportation infrastructure is getting worse and worse, so you have areas like around Cambridge's Alewife that are becoming massive traffic bottlenecks as they're building up around it. That's just not scalable.

This is the best explanation of the phenomenon I've read. I think you're exactly right.
I have a similar story - one of our products at $DAYJOB is a kind of CRM/ERP SaaS for a specific niche.

It pays its way, but at a huge cost of time spent on support and maintenance. When non-trivial feature requests come in, we can't feasibly drop everything else for long enough to implement it. We signal this by asking the customer to pay a lot (compared to our SaaS subscription price). Usually this dissuades them.

Every so often, we lose a customer -> support dies down -> we can add some real direction and features to the product -> we gain more customers -> we get swamped under support and maintenance. The cycle continues. I don't know what the solution is.

With spreadsheets, the customer can always fall back to cobbling together a new report or visualization by themselves.
I would love to run the same benchmarks here, have you got a github repo or a write up somewhere that I could read?
The parent post is suggesting that 5 Million customers does not in any way imply 200 shards. It's much more likely that with 5M customers you have 1 or 2 shards. That's 4KB (one document) per customer.
Fraud is a criminal offense where you lie or deceive people about things. For example on contracts. Where you can end up in jail. Smart contracts don't fix this.

A contract dispute is where both parties are truthful, but disagree on the resolution of the contract. This is the part smart contracts fix.

And it's how insurance companies deal with these problems today.

I was reminded of Godel too. For me, it was the part of the article that described Russell's finding of statements that led to paradox, such as "I am lying." If you're allowed to talk about "the set of all sets", then you can state things that can't be dealt with logically. That reminds me of Godel's Incompleteness theorem.
You create a reference cell containing an empty list. Because the cell is mutable, it can't have a polymorphic type - it must have a monomorphic one. How do you determine at runtime the type of this cell, before the first time you mutate it?

This is not a good rule of thumb, it depends on what your research is. In most cases I've dealt with (security) the academic software displays terrible performance characteristics and is very buggy. The industry application that surfaces years later does not have these problems but it doesn't present anything novel.

Redfin is a big pile of nothing. It's a glorified real estate agency which is itself an anachronism or soon will be.

You can easily find online or other brokers ready to "sell" your house which just means listing it on the realtors' association multiple site listings for 1% or even a few hundred dollars. The realtors association still control everything in terms of having all the data on homes for sale.

They could have some opportunity in giving buyers rebates i.e. having a 1-2% margin for buyers which most agents don't give, mostly because it's a lot luck to find a buyer than to represent the sell-side.

The idea that it's worth around 8x revenues...a low margin business as a real estate agency is...is a stretch, though to be fair, their revenues are fast-growing without that much of a marketing spend.

Not sure how their quarterly sales vary (seems like a lot in their profitability at least) but their latest quarter was terrible with only $6 mn in gross income on nearly $60 million in revenues and then $30 mn in operating expenses.

They claim to have helped users buy/sell $40 billion in real estate last year but showed just $270 mn in revenues which is something like .8% of that market value (while it should be in the 1.5 to 2.5% range I think). Not sure why that it is.
