That's one (important) aspect. When looking at a team or individual I check wiki contributions, design documents, commits, code review feedback provided to others, ticket queue depth/volume, "cm" volume, customer forums,

No, it works both ways. Ive personally been in the room where my VP and ~2 others favor product/feature A. The other ~6 people favor product/feature B. Everyone reports in to the VPs org. A round of discussion and it ends with &

Too late to edit, but thought I should clarify. Nice introductory post and demo code for the concept. I wrote the parent in a hurry after work. I meant it as a mix of earnest questions and comments that came to me as I read through. Apologi

A few questions. Have you looked at doing batch token assignment or "leases" from the centralized source to the workers? Ie request 10 tokens from the central "bucket" when the local "bucket" reaches zero. You

Id be very surprised. I worked in infinite loop for a couple years. The central courtyard was full of people every day around lunch time, with constant singletons & small groups. And big organized events used it every couple of weeks.

Its not about encryption, and real world concerns are echoed there. Radio (or other broadcast) gives up lots of signal intelligence; times, location, correlation with other events etc. A tightly collimeted/focused media (like laser)

Im personally not a fan of the new review & promo process. There seem to be some obvious, and some hidden, risks. In my opinion it reduces depth of the content, breadth of the review, and broader exposure/evaluation inside the org.

Is it really any different in practice? TPM is installed in basically every computer used in basically none. Even though its been a uniquitous "standard" for two decades its effectively impossible to correctly do attestation. Simi

Check out "Opal" and "SED" https://en.m.wikipedia.org/wiki/Opal_Storage_Specification . Many (most?) drives support it these days. When I briefly looked a year or two ago basically all drives had the

Disclosure: I currently work at AWS and have a bit more than passing familiarity with large scale storage systems. I know what erasure encoding is. I know from experience just how wrong things can go. The passing comment of distribution of

The exact values may be off, but that is how to think of it. Losing any specific object is less likely than earth ending. But these are providers with many trillion objects. In that case there are a handful of objects that are going missing

There are a couple of interesting infrastructure/business trends driving this across providers. The call out of 12ct for throughput and 2ct for storage actually reflects a typical blended data environment. In short, data access frequen

WRT to "the cloud" are you conflating infrastructure, systems tooling, and operations? Theyre not the same thing. For example I cant imagine why a monitoring system would necessitate more "operations" costs than an email

I've been a bit perplexed by the industries obsession with "operations" for the past decade. Constantly striving to decide what is it, who does it, and whether it's shunned or exalted. My current workplace has convinced

Ah. I dont commonly see this use case called out. If a CDN supports verbs like POST PUT this should "just work." I dont know what support for write through vs write back etc looks like.

by donavanm 10y ago
Can you clarify "crn", whats the use case? From context I think youre looking for "PUT/POST" support and or layer 3/4/5 termination closer to the end user to bisect latency/loss/windowing?

Ah, i must have missed the thread intent. I thought you were responding to the utility of limiting/optimizing cache write rate.

"It Depends." If youre doing "random" writes down to the block dev, like updating a filesystem, it can be very bad. You'll end up hitting the read/update/write cell issues and block other concurrent access

I believe the term youre looking for is "cache admission policy." This is an adjunct to cache eviction, both are needed for success. I'm very curious what a highly efficient insertion policy and trivial "eviction" p

It sounds like you were missing the "Content-MD5" header on your put requests. As i recall S3 will return an HTTP error response if the complete object does not match the Content-MD5 the client sends. The other issue with the HTTP

Are you starting from a false assumption? Delegation seems like the logical answer. Content publishers already delegate out a DNS label/domain for CDNs. Why wouldn't they also delegate a DNS label/domain to a third party for

Fundamentally you dont. Or ive never seen an actual solution in practice. Physical hardware comes down to trusting the layer one/two domain and (usually) the mac address. With virts you trust your infrastructure to pass through some bl
