Show HN: EdgeKV beta – A key-value store at the Akamai edge
Hello HN!

I'm Jeff Costa, product manager at Akamai for EdgeKV (and a few other things). As a CDN running hundreds of thousands of servers in 135 countries, we know something about caching, networks, and distributed computing. After we launched EdgeWorkers, our serverless compute product, we quickly realized that where data was located was critical. If you run JavaScript functions at the edge, but have to reach back to a cloud database or a single datacenter, the round-trip latency could negate the performance benefit. EdgeKV was built to solve that problem.

We decided to start with a key-value store layered into the CDN model. The focus was making database reads as fast as cached object reads, while writing data quickly. We built a new cache layer for EdgeKV to ensure that when EdgeWorker code needs data (ex: to make a decision inside a function), it pulls that data from the adjacent data cache in ms. For writes, we landed on an eventual consistency model as it provides reliability via redundancy. When a write is made, we send it to multiple nodes in our persistent backend, then update any copies of it that exist on edge servers - without impacting read performance. This means that when you write a value, it may return stale data for a short period of time when you attempt to read it - but will eventually return the latest value in subsequent reads. The period of time between write and read convergence is called the "inconsistency window," and our goal is complete global data writes within 10 seconds. Ten seconds.

Think about what apps and data can benefit from living closer to your customers. Beta signup form, GitHub, and docs listed below. EKV is beta, so expect a few warts. We're excited to hear your questions and feedback on what we've built, so please reach out or leave a comment below. Thanks for reading!

Has any rigorous study shown that blacks are more likely to die in police encounters after adjusting for income level and crime rate of where the encounter takes place?

If so please provide a cite or link.

Although out of thousands of cops in the USA I am sure there are some genuine racists the notion that in 2020 cops would be killing blacks intentionally at a higher rate seems ridiculous. 99.999% of cops want to have an easy shift, get a donut or two, write a couple tickets, watch the years go by, retire early and collect a pension. Plenty of poor and middle class whites have been killed by abusive individual cops over the years and yet the reaction is not tribalism, rioting or generalising the actions of few bad cops to the police force as a whole. I agree America has massive problem with overly militarised police but this is not a racial issue. It stems from the drug war and the ease with which criminals can get high powered weapons in America. See North Hollywood Shootout.

> Building an audience with a cheap tool

Absolutely. It's a common startup tactic to release a product that costs more and does less than existing alternatives to get market share and brand awareness. This is just basic stuff. Marketing 101.
I had a brief panic about it the first time I took the train to NYC (in high school) because all I knew was that I had to get off the train at "Penn Station" and I saw that on a sign as we were pulling out of the Newark station.
Inherent worth only provides a price floor in a market. It only plays a partial role in determining the ceiling.

For that you need to incorporate a whole manner of values.

Cost, direct, indirect, amortised nor not.

Value proposition, both yang ble and intangible.

Scarcity, uniqueness and availability, time to produce, time to reproduce.

This is why it was so abhorrent when bankers and media brought up inherent value of GameStop, it's one small part of the equation and has very little to do with the situation.
I doubt you can 'fully comprehend it'. Folks peddling new-age advice thrive on misunderstanding. They get more folks interested if they don't exactly say what they're saying. Everybody has a different interpretation of bad writing. That's why its bad.
The right are not the ones cancelling people. It's better to have everyone fighting like hell than one side censored into oblivion.
"everything would be perfect if only EU stopped interfering with our perfect country" will disappear from political speech.

That doesn't seem to be disappearing. My guess is we will be hearing a lot more about the EU for the foreseeable future.
> who let themselves be underpaid

So what should these people do instead? Stay where they are and get paid much less?
This is a mis-understanding of the OP. The internet is inherently a very __useful__ tool. The problem is that social-media companies have turned the need for social interaction into a crack-like addiction (by design) where peoples attention-spans are being sold piecemeal.

Social media is often a junk-food version of social interactions designed to sell ads to people. This leads to short attention spans and social anxieties. How many dinner tables have you sat at where couples sit there on their phones, and scarcely talk? This seems commonplace now...
I wasn't listing problems but ways governments can regulate crypto-currencies even if the network itself is out of reach.

I'm myself in favor of cryptocurrencies (though, definitely not Bitcoin) AND for some level of regulation.
I’ve spent almost a decade in the productivity space (founded Shortcuts at Apple, fka Workflow) and everything is always confusing.

Everyone is seeking the holy grail of computing (“the computer does exactly what I want and it’s a seamless experience”) and there are a billion and a half ways to attack the problem. Starting with a “hair on fire” problem and expanding to other hair on fire problems is not a wholly unreasonable way to go about it. It’s important to have a larger vision, but execution is perhaps the most important in this space (as with most consumer tech).
The EU isn't perfect, but you'll struggle to argue that it hasn't expanded peace, prosperity and human rights across the continent. This is motherhood-and-apple-pie stuff.

The ECSC then EEC did that, and of course NATO, ECHR, Schengen and various other institutions and agreements. The EU came into existence much later and claimed credit for things that were set in motion decades before. Noone would have voted to leave the EEC, the EEC was great.
Is the card available in Colombia or Mexico?
Yeah, that's what I was thinking - people are mixing up GDPR with the "cookies law" that mandated the [Accept All]/[Maze of Settings] choice on all websites that want to use cookies. The cookies mess was pre-GDPR.

I'm an American in Western Canada and I'd agree with this. Absolutely nothing I couldn't get in the US, save for Nanaimo Bars and Letterkenny, and you can get both if you're in a border state like WA or ND. There are Tim Horton's in the US (and they suck these days anyway).

The culture is basically the generic pseudo-leftist stuff you get via pop culture. They love their virtue signaling here, but most of the talking points aren't anything you couldn't get in any big, US city; hang out in Boston, Seattle, or NYC and you'll get the same thing. For all of the progressive talk Alberta is Snow Texas, the Prairie Provinces line up pretty well with Indiana or Kansas, and Ontario has it's own mini-Trump in the surviving Ford brother making it to the Provincial-leadership level.

In exchange for healthcare you've got a housing and business climate that's basically owned by either 1) Big Oil / Big Gas / Big Mining, or 2) Foreign firms. Housing costs are insane -- Vancouver is the most unaffordable city in N. America since, unlike SF, salaries didn't keep up with housing, and it's basically a place for Chinese / Russian / Indian / Saudi citizens to park money to get it out of their respective countries.
You could say the same of a high quality replica of the Mona Lisa or a Picasso. It's all about the status of having the "real" thing.
If you wanna argue it's vain, I agree, but many people find it impressive at the same time they look down at any copy as pathetic no matter how close to the original, even when to the point to being identical.
Let the spam kings rejoice.
Agreed. More services does mean more context switching. The most pure microkernels will have many, and the more practical ones may consolidate some services to reduce context switches. Also, some types of IPC can have a very lightweight context switch; they typically transfer only a few words of data, but this is usually mitigated by shared memory.
It seems that there is more of an emphasis on defense in the NCAA vs the NBA. Makes for a more interesting game.

We could let users sign a bill of sale. That could either be packaged together with the original proof of purchase in a private transaction, or published to avoid a "double-spending" situation where both the old and new owners claim the item.

Or, have the users do the transaction on one of these participating websites and create a new proof-of-purchase and revoke the old one.
You don't see far left communists setting up autonomous zones and executing Trump supporters who come near?
What's your expectation for how effective that would be? Let's compare some existing bans, say prohibited cannabis farming:

* Large energy use (lights, fans, pumps?)

* Very characteristic energy use (high, relatively invariant)

* Massive government budgets/surveillance to attack producers

* The need to move non negligible amounts of physical goods

* Moral campaigns by governments and social groups that it's bad for society

And yet the banned-market drug trade revenue is something on the order of 80 billion dollars per year or 220 million a year.

Bitcoin miners, currently:

* Large energy use (fans, HVAC, ASICs)

* Very characteristic energy use (high, relatively invariant)

* Mix of jurisdictions banning or allowing it.

* Only need about 2G / Shortwave radio worth of bandwidth to produce blocks

* Moral campaigns by governments and social groups that it's bad for society

Miner revenues need to be on the order of 10-50 million USD per year to sustain themselves. That's almost 10 times less than the failed (relatively global) "war on drugs"

Add to it that by defecting from national socialist forms of storing one's wealth, rather than just momentarily indulging in vice, one improves their position, I'd suspect your hypothetical ban won't work that well.
Thanks. It looks like .NET core works (but is unsupported) on FreeBSD. That’s future proof enough. I have a gripping day of LastPass migrations ahead of me. :-)
I think you are forgetting what it was like when the "black lives matter" slogan was first becoming popular. If hadn't already been exposed to it, it was very easy to respond "incorrectly".

For example, here's a case of a Democratic governor, running for president, getting caught by this:

https://www.cnn.com/2015/07/18/politics/martin-omalley-all-l...

And here is Hillary Clinton, falling into the same trap:

Is there any actual evidence that the paradox of tolerance is correct? I suspect people stopped taking it seriously (and mentioning it in discussions on speech) because it’s advocates always seem to expect everyone to take it on faith, instead of providing a real argument to support their claims.
Exactly, these comments would result in bans if they were about black people instead of south asians.
No, at the point of being identical, the distinction evaporates. That's my point I guess.

Imagine for instance that I register the image with a different blockchain. Do I now 'own it' too? Yes, I do, by this modern tortured logic.
Thing is under the veil a lot of caste sentiment is around. There is much closing the ranks among upper castes even in well educated circles. Peoples surnames and colour of skin seems to matter in social interactions, and there is considerable 'them' and 'us' mentality.

Also upper castes continue to propagate caste names in naming children which acts as a badge to upper caste identity.

Important positions in both government and industry seems to be filled with people from the upper castes.
>Stocks, gold, Bitcoin, a house you live in (not rent) don’t produce anything (unless your stock has a dividend).

Houses: https://en.wikipedia.org/wiki/Imputed_rent

Stocks: You're literally owning a share of a corporation that produces stuff. Producing a dividend (or buybacks) isn't guaranteed, but that isn't that much different than owning a farm, which can also fail to produce a profit (if costs exceed expenses).
Nope, it's a DDoS:

"A DoS attack is a denial of service attack where a computer is used to flood a server with TCP and UDP packets. A DDoS attack is where multiple systems target a single system with a DoS attack. The targeted network is then bombarded with packets from multiple locations."

Multiple apps engaged to notify 1 human, multiple systems attack -> single system.... DDoS.

You could hardly call it a democracy.
I never truly understood that - prohibiting companies outside of US from getting American customers. If the US govt doesn't want that to occur maybe they should police their citizens instead and see how that goes? I mean, an American citizen signs up for a service that he's forbidden from using and somehow that's the company's (that's offering that service) fault? Looks to me like trying to pass off doing your bidding to others.

Thank you very much :-) yes you can put anything you want into the search space. Even pandas dataframes, numpy arrays or classes. Here is an example: https://github.com/SimonBlanke/Hyperactive/blob/master/examp...
And ironically, that's when we get into fragmentation issues for arrays!

Growing the array from size 8 -> 16 -> 32 -> 64 ... 1024->2048 makes it harder, and harder to find contiguous, exponentially growing chunks.

If you have a fragmented memory allocator, you may run out of memory due to fragmentation. In contrast, if each of those elements were a small and constant-sized 8-byte chunk (or 16-byte chunk), then you'd be able to fit that small chunk anywhere.

-----------------

Anyway, I agree with you that vector.push_back() is an outstanding methodology on modern systems. But Linked-Lists aren't as bad as people make them out to be.
With the option of using a burner sim, I thought about the fact that at least in the US, most places you would buy a prepaid sim will also have you on video surveillance when you purchase it.

Maybe I've been watching too much TV, but would it be better to pay some random person to go into a store and buy my sim/chromebook/phone in cash and then bring it to me at a location I know does not have video surveillance?

The speaker doesn’t mention any blackouts, she only describes how they shut down few illegal crypto farms (only 230 units of unspecified model or power consumption).

I believe there is more to the story and that doesn’t mean that there is no blackouts, but for completeness sake this video is incoherent with this thread’s headline. Blackouts may be caused by e.g. shitty, cheap, unmaintainable grid, or by local corruption that feeds from these farms and doesn’t officially demand higher loads from energy providers to cover the difference. My (completely subjective) opinion is that not taking it at the face value is a pretty safe move. (Disclosure: russian, non pro-crypto guy)

You're right, I'm sorry. I fear what these trends could bring, but I understand that we have a community and culture that we have to maintain here.
Except that society has a mechanism for for enforcing social norms: laws. Premarital sex might seem like an evolutionary advantage, unless you live in a society that murders you for such activities.

You are right though, which is why high-status in a society are "allowed" to break social norms with no consequence.

Does anyone know how the things provided by .DS_Store worked in classic MacOS? Before OS X? IIRC there weren’t such files but folders would remember icon placements and custom folders/file icons
CS6 was the last. But even on Intel processors, running it on Catalina or later is crash-prone and requires a fair bit of hacking around. The main problem is that there were still chunks of 32-bit code in there and macOS has stopped supporting that.
Also if an intellectual property law is passed to benefit the silicon valley establishment as a result of silicon valley lobbying it is apparently not "cheating". Cheating is when those bad foreigners don't care about those intellectual property laws.
Sorted linked lists are also especially-not-useful, because you can’t binary search them, which is often the main benefit to having something sorted.

The only thing a sorted linked list is really good for is being able to cheaply peek/pop the lowest- or highest-valued item, and a heap is almost always better for that use-case in practice.
Yes, I think altering the number of players on the ice is way more radical than changing the size of the goal by a few %... I wouldn't think they are even comparable!

Yep, for me the peak right now is an IDE that has a great VIM plugin. You get the best part of vi (the insane productivity and wrist health increase that is modal editing) with all the best parts of a modern IDE.

> This problem is pushing a lot of people to go to department stores with their own installment credit, but with incredibly expensive interest rates (+70% APR)

Surprising. At least in Brazil interest-free installment payments are extremely common, so much that prices in stores are often advertised with the installment amount.

One question: With all the problems with credit cards you mention, why didn't you build a better credit card?
I think some of the furor over bitcoin power usage is overblown. It's true, as crypto folks say, that the power is doing "something."

It's more that...a system where you will pay anyone who finds any cheap power source anywhere in the internet-connected world no matter how they get it is obviously going to have awful externalities. Even though most people will be reasonably ok about it, enough people we be shitty enough to turn any worldwide no-checks system into a hellscape.
So I tried to put content on rarible. It was $900+ to create a ERC 721 token, $13 to create a rarible token. Will be looking into other options.
Agreed. I didn't suggest that supply control increases quality, and yes it does increase price. However in Canada it appears that the increase in price has returned a benefit to the consumer by the gov't restricting the use of certain drugs.
