The tweet doesnt mention dates or the coverage. Second I believe youre underestimating the scope of the problem. Amazon has thousands of teams, even more services, each with their own priorities, and innumerable different access patterns, d

Sure. Lots of companies and employees are located elsewhere. And software + services is a heck of a financial drug. I dont think that changes the underlying message of how to think about employee comp or business opportunities.

If you are an employee there is little to no relationship between your output and your compensation. Employer employee relationships are based on the cost to the employer to secure equivalent or better output. Secondly, yes $10M per emplo

There have been rare changes, like mandatory API version upgrades or some features being turned off. I do not recall anything being removed without a (better) replacement available beforehand, let alone entire simply services being turned o

It seems like target users would be something like industry and logistics handling? You need a moderate number of mobile clients, complex physical topology, and very good coverage? The number of sims, 10s to 100s, seems to low to get in to

Lately Ive been going the other way as an interviewer. I try to get the candidate to deeply explain their system design; starting point, requirements, conflicting priorities, compromises, etc. Alternatively we can pivot slightly to solving

That’s identification. It doesn’t account for other modes such as candidates having people “coach” them in real-time, either virtually or in the room. Yes, it absolutely does happen. The risk/reward of “cheating” a job interview is fan

AMZN is three global mega corps in a stock ticker trenchcoat; consumer retail, digital/devices, and AWS. These days you could put Ads in there as well. As I mentioned elsewhere those huge numbers are specifically about about retail ope

The article title from the editor is junk, or misleading at best. The attrition and hiring comments were specifically about retail/fulfillment/operations and the degree to which that scaled up in 2020-21. This was very clear in bo

Ignoring the “how publicly traded companies equities function” aspect. What would be the medium to longer term outcome of Apple “making better products?” In an open market I would assume that better products drive new users and/or incr

Optane is/was sold as pcie/nvme block devices. I use that for durability compared to TLC flash. It was also sold as DRAM format hanging off a memory controller and presented as (magically persistent) pages/bytes to the os&#x2

The “cheap” optane nvme devices work great as ARC and or Zil. I also use one as temp storage for streaming nvr data and post processing. Id buy another today for the durability properties alone.

Be careful on licensing anything that gets linked/deployed in to the customers environment. There are many large and small enterprises with “strenuous review” policies, if not blanket bans, on licenses like AGPL. This is not to argue

Hey Luca, some thoughts from working on similar systems. Visibility is the cause & lesson learned on duration. It's worth simply paying for 3P distributed RUM. Make sure you can get down to /24s & ASNs as well as breaking

I've helped build and run similar distributed systems with deep load balancing and network interactions. There are some packages out there that do bits and pieces of the problem. I don't know of anything COTS that is a suitable li

A lot of this can be from (un)intentionally trying to maintain separation of responsibilities between different teams or developers. Decoupling, interfaces, etc all add up and pretty soon you start building based on what's already done

Yes! This is also the issue that makes large cloud providers very hesitant to provide anything that even resembles “terminate services at a spending quota.” The cost of damaging an actual customers business is so so much greater than the

Hard rock mining is pretty insane when you look at the history. In california the Empire mine hit ~3.3km deep in the 1950s before closing due to costs. That's about 2.4km below sea level. https://en.wikipedia.org/wiki&#

Indeed, theyre almost always "residential security containers" at best. Which means the manufacturer can't even be bothered to assert that it would take 5 minute to break in to with hand tools.

Isnt this a bit reductive? The other side of the fence is “How would an independent SRE org be able to fund/influence/prioritize inside the product org.” And Im pretty sure the answer there is > A dedicated model can't wor

Also in case 1, of a sale, you can issue additional warrants to “friends” and key “investors” as an incentive. Which further dilutes the actual post merger equity pool that everyone is buying in to. SPACs are free money for early investors

As others have said, make sure youre using the local cache first. Once youre beyond that most CDNs support advanced “cache keys”. Beyond the URL you can use (parts of) the query param, cookies, or headers to construct a cache key. You could

Your summary is about right, but these can also be used to present (virtualized) nvme devices to the host computer. Imagine presenting arbitrary hardware to a host, and being able to control all of that entirely out of band from the host. A
