Kalepa | Senior Backend and Full-Stack Engineers | New York, NY & Completely REMOTE| Full-time | VISA https://angel.co/company/kalepa

Software engineers at Kalepa are solving interesting and challenging problems at the intersection of data engineering, distributed systems and microservices, and machine learning. You will be working across the stack, building intuitive and performant microservices, robust data pipelines, beautiful frontend apps, and everything in between. You will be working with a small team of full-stack, data, ML, and DevOps engineers working in a modern stack.

Kalepa is eliminating deadweight loss in commercial insurance underwriting. Kalepa's AI-powered Copilot enables underwriters to rapidly evaluate and optimally select risk. By analyzing trillions of points of structured and unstructured data, Copilot augments underwriters with insights and recommendations on every risk: is that business a family restaurant or a dive bar with a mechanical bull? Does that contractor have an excellent safety record and merits a better rate? Does that motel represent a sex trafficking and prostitution risk? Copilot answers such questions for underwriters in seconds through a battery of NLP and computer vision models on a massive, and fast growing, data set of businesses in the US.

Kalepa's team members bring experiences from Facebook, Google, Amazon, ClassPass, Atlassian, APT (acquired by Mastercard for $600M in 2015), MIT, Berkeley, UPenn, NYU, and the Israel Defense Forces. Kalepa's HQ is in New York City and we have team members around the globe. We are backed by IA Ventures, investors in Datadog, TheTradeDesk, Transferwise, Flatiron Health, and others.

Cool let's implement a distributed database when it turns out there's no reason to.

That's not crazy - most people dont have access to enough stuff to leave one or two datastores, a consistent approach is fine.

Yes, but those are subjective as well; there's no objective test for who is virtuous and who is not. Everyone has to judge that for themselves.

For my purposes I've often found that static-binary+cgroups+chroot+permissions gives you 90% of the isolation benefit of various container systems (docker) with like 10% of the pain.

I'm also not happy with Ubuntu's move towards snaps which also seem to increase complexity and overhead with minimal benefit.

An app-as-directory setup, like the one that was used in NeXTSTEP and is still used in macOS, also seems to work OK.

> If you come to a situation where a prize hasn't been claimed and there's few cards left to be sold

You'd have to also account for cases where the prize-winner just hasn't scratched their card yet? (Or, as you say, whether and how this has been accurately reported)

> If that happens you need to do a bit of optimizing risk, assuming you have a limited amount of money to potentially lose. Kelly Criterion will have something to say here.

It seems to make sense that they've set up as an "investment fund", since they need a bunch of cash to buy the tickets in the first place, and even more cash to reduce the fund's risk enough to get an OK from the Kelly Criterion.

(In extreme cases full-Kelly can advise you to borrow cash at your own risk, but the odds have to be wildly in your favour - if they were dependent on one ticket for a net profit, that doesn't appear to be advisable)
Eh, that depends on how you define "win".

If you mean sell as many units as Apple and never get bought? Sure.

But as someone who also owned an OG Pebble, if the "Pebble-way" was actually better, it would have won.

Winning might have meant getting acquired, or even just competitors making devices similar in spirit to theirs, but it'd still be a victory.

The "Apple Watch way" was the anti-thesis to the Pebble philosophy with it's needing daily charges and it's color screen, and trying to be a second phone on your wrist with beefy specs. While the Pebble was trying to be _literally_ a smarter watch.

And Apple's way won out. People just preferred that.

Ah yes, people already waste fucking hours putting in the most ridiculous menial data into the CRM because management forces them to because Salesforce convinced them it would somehow help their business to know what color the customer's underwear was.

Now instead they can get more efficient at wasting time by using both slack and crm at the same time!
I would argue a traditional education in the humanities with the internet era is a moot point. You can do that without going into debt slavery via college loans. Instead of learning from a professor, watch some guy on youtube. Practice a lot. Make stuff. Join the literally endless communities that do the stuff you're doing.

The reason kids go to college is to get a good paying job. I hate to say it but if you're a kid who does not have affluent parents or don't live in an area where there actually are legitimate jobs in that field, it's 100% on you for doing that. I mean the opinion that those jobs don't exists isn't a stereotype for a reason. Students can get those jobs, but there most definitely aren't where they went to college typically. If you live in LA, Chicago, NYC; sure those could very well be viable career paths. In the middle of Idaho? Maybe you should reconsider who in Idaho is going to hire an artist outside of the small town that is their capital.

I disagree. Historically there are plenty of examples of communities that have managed to get along for extended periods with reasonably good outcomes. What we humans don't (yet) have a good handle on is how to protect such communities against invasion from outside--other people outside the communities just won't leave them alone, but insist on trying to make them part of some larger social experiment.

It's also to maintain the capability. You need to keep people continuously employed in that area or else you run a high risk of losing the ability to field new aircraft.

It is not so different from subsidising farming (similar pros and cons) to ensure food security.

There is a lot going on in the supply chain that you need to maintain at a baseline level if you ever expect to have to fight.

From a very macro level whatever airframes get shipped may matter less than maintaining all the specialised knowledge and suppliers that you need to produce them. "Looking after the machine that makes the machine".
OMSCS by Georgia Institute of Technology is by far the best course I have come across. You get a degree too in the end. Caveat: It takes a lot of effort. It is like doing a full time course and the degree they award in the end is indistinguishable from a full time degree.

This sounds like how stat() normally works. You can read a directory if you have x permission on it.

Is the sandbox supposed to block stat() if you don't grant an explicit permission like 'full disk access' but it isn't doing that properly?
> If you are working with AWS your application and your whole organization is at the whims of Amazon.

Part of freedom is the freedom to do stupid things.

> You will not even be able to migrate if you are tied into those API's and services because they are not same across cloud providers.

VPCs, Instances, Load Balancers and Storage are roughly-equivalent everywhere and the differences between are mostly-trivial. For the rest of the "shinies" they offer, well, see above.

> You don't even own the data or compute resource hosted on such cloud services because just by a single notice from a government agency your account will be blocked without access to your own data or compute resources.

If you think this doesn't also apply to your physical racks in datacenters, you've got another thing coming. Ask Lavabit.

Design for this in your strategy. You can still "own" your data and have it hosted in the cloud too. There's no reason to have to be exclusive.

> In terms of technical freedom you will have less of it and will be tied into proprietary extensions, API and services offered by those cloud providers.

As mentioned before, stick to running in instances and you're no differently off than anywhere else you can operate.

> On the other hand for self-hosted infrastructure government notice will not block access to resources owned by you and data in those resources. You can respond to notice and continue using those resources until court rules.

Absolutely not. With a warrant, the authorities will come and take your shit. They have guns. You don't. Ask Lavabit. Ask The Pirate Bay. Ask any blockchain drug pusher.
They'd have to acquire so much more - it's AD, Office and Exchange that keep Microsoft embedded in the enterprise.

Depends on element size and some other stuff, but if it is a singly linked list, and truely random insertion location, iterating to that location is N/2 on average, where inserting and copying the rest of the array is also N/2. Small elements and the array could still be much faster since they are all prefetched during the copy, vs jumping all over memory during the list iteration and potentially stalling on each for ~200 instructions waiting on main memory.
Maybe I can explain this in computer terms.

Think of DNA as read-only. It's a series of molecules that represent data. Cells read the topology and molecular interactions of those molecules and determine information from them.

Now, because the DNA is read-only, the permissions are super restrictive. Which means if you want to access that data in the DNA, you need to go through an intermediate, which, when it leaves the restricted area, is ok if it gets destroyed, because that original copy is still intact. That's where RNA comes in. RNA is designed to be mutable and temporary. I think of it like system memory. Reboot the system, and you lose it all. Want to protect it? Write it to the disk (DNA)., Similarly, you don't mess with files right on the disk - first you read them to memory.

So, RNA is basically DNA that's been read to memory, and can now be messed with. You can do something like execute it, which would be analogous to translating it to proteins. The process is similar. While 0s and 1s might translate to microcode calls (i.e. physical action on part of the computer sending electrons around), RNA translates to amino acids, the building blocks of proteins, which are the physical components of cells, and do things like...well...move electrons around, among other things.

The way this works is that while 1010010101110 (I have no idea) might be some microcode call like OR or NOR, RNA bases (which are derived from the transcribed DNA) might say things like AUG, which tells the cell "OK go get the Methionine amino acid" or UUU which means "ok go get the phenylalanine amino acid". Chain enough amino acids together, and you get a protein, which essentially is a function in the cell. For instance, a protein of a specific sequence of amino acids might go fight off viruses. A protein of a different, but still specific sequence, might go produce energy.
Citing increases in fraud and retractions, this article makes the case that as funding has increased, scientific quality has worsened. (Which is counter to what I guessed above!) Pursuit of scientific knowledge for its own sake replaced by obsession with grant cycles.

https://www.jamesgmartin.center/2020/01/the-intellectual-and...

But lots of other things have also changed that may or may not be causes:

- many fewer tenure track positions

- many more jobs in industry that require or value a 4 year or advanced degree

- obtaining a college degree as a right of passage seen as increasingly essential to you g adulthood

- the rise of data science: more jobs in industry that have access to lots of data and demand scientific rigor

- the rise of private cloud supercomputing (is deep mind) vs, say, a public university's cluster

- the obsession in some foreign countries of getting advanced degrees from American universities, creating essentially a guest visa workforce that is easily abused

- rise of Big Tech which has money to throw at things like protein folding

The fact that this article is about “justice” based on “case” and the word “bias” doesn’t appear in the article is a pretty good indication that whatever navel gazing is below the fold is not fit for real world application.

I understand it’s on a philosophy site, but it sets out a pretty bold stance from the outset that is amply contradicted by real case-based law that has been established specifically because bias has repeatedly, systematically poisoned justice.
The overwhelming majority of consumers of enterprise software aren't devs, so you're correct to speak to your bias.

With P2P you still have to have a device that's always on, which most people don't already have, so that costs money. I actually think a VPS is cheaper than a home server. But either way it costs money and people don't want to spend it.

And software development costs are another thing that needs to be paid for but can't.

Camera can record video, 720p will probably be a limit unless you don't mind lower than 30fps framerate.

Here's my test recording from a few weeks ago: https://megous.com/dl/tmp/vid-720.mp4

You can only encode via CPU for now, and at best you may be able to encode to x264 at the ultrafast profile. (don't remember which one is fastest, but it's the fastest one) Encoding with the fastest available profile just happens to run at 30fps, so it's still not enough to for realtime encoding even via CPU, if you account for the fact that CPU will start throttling soon after you start loading all 4 cores at once to the max.

So I recorded the above by saving raw frames. :)

Video image quality sucks of course. (that frame counter is all white uniform background in reality)
I've been on google meets all day since march and have never froze. Plenty of huge conference calls, screen sharing. Works great for me. Missing some features of zoom, but the video/audio quality is just as good in my experience.
Some 20 years ago, when I was a kernel developer with high performance requirements, my favorite data structure was a linked list of smallish arrays. Each array was small enough to be cheap to completely rewrite on insert/delete, if you needed to e.g. preserve insertion order; most of the time, it was enough to preserve order only across the linked list, treat each array like a hash table slot, or sort at consumption time.

A question to those who know both Lisp and Python. What one you generally prefer for quick and dirty hacks? Which one do you prefer for writing applications that will be used and maintained over a long period of time?

I know both Python, Common Lisp and Scheme but I find myself reaching out for Python every time I have to write a quick and dirty hack. I believe this is due to more familiarity with Python which makes me more comfortable with Python. I am eager to know what others' experiences are. Maybe it will convince me to go all in and use Lisp all the time. :-)

While I agree with ‘learn the fundamentals’...

> These aren't college majors.

They most certainly are, at many colleges and universities, not just Purdue. Game Dev in particular is a very popular CS sub field that a lot of schools have recently developed complete programs in. Data viz & web UX majors are super common.

Each one of these has it’s own set of fundamentals. There are some overlapping fundamentals among them, parts that are common to Computer Science in general. And there are fundamentals in each of these that a general CS degree doesn’t cover.
How many people on earth can find and exploit something like this? Less than 100, maybe less than 1000?
“Most” is perhaps an expression of your experience. The actual most that objectively happens is such routine banal minor infraction enforcement and intrusive stops that affect a minority of the population that it’s understandable that you can’t see it or maybe even quantify it but it’s constant and it affects “case based” judgement severely. Many people under this kind of jurisdiction are already facing potential lifetime sentences before they’re adults.
