There's a zillion things you can estimate this way. A lot of sites use sequential cookies, user IDs, etc. Until about a decade ago UPS tracking numbers were sequential for each shipper which made it trivial to estimate output for onli

Seems like for C++ builds you are always going to want the most cores for the money, even if the single core performance is a little worse.

True, Intel's part numbering scheme has passed beyond all reason. Think about the i9-9900K/KF. Existing SKU, in stock at Newegg for $479. You don't get quite as many cores but you get a lower price and higher single-core per

The 9980XE is just a really large/fast Skylake CPU. Skylake is years old. If you wanted this level of performance from Intel you could have ordered the Xeon Gold 6154 way back in 2017. It seems fair to call this a 2-year-old part. A

These railguns also have synchronized pulsed power systems that are quite complex. The University of Texas has been researching this stuff for decades. Here's a simple paper I Googled up https://apps.dtic.mil/dtic&#x2F

In the West most "ranchers" are just running herds on BLM leases. It is not "their property" by any definition. By contrast virtually all ranches in Texas are on private holdings.

Article doesn't indicate the road is private. How do you know? As a backcountry motorcyclist I'm accustomed to coming upon roads that are "private" because some rancher decided to hang a sign but in reality it's a

Is that true across the nation? I know California isn't the whole energy market but their renewable energy mix is solar, hydro, fission, wind, geothermal, and biomass in that order. It's true that non-hydro, non-solar sources are

That can’t really be the reason because SF has approved numerous such mergers and expansion of gigantic single-family structures and they steadfastly forbid subdivision of buildings no matter how large into duplexes in the vast majority of

It isn’t city policy to prevent such mergers but it is city policy that you must get a permit for such a merger before actually doing it.

Sure. In this specific case of a kv store it's hard to imagine how to simplify it dramatically from protobuf. As a proto you might have: tag-length-key-tag-length-value. Instead you could store the key and value lengths in host form
21.
by shereadsthenews 7y ago
For simple protocols protobuf decoding has no taken branches. I.e. if you only use the first 15 field numbers (all your tags are 1 byte) and if all the types are the expected types, and if all the variable-length items are < 128 bytes l

by shereadsthenews 7y ago
If you knew your keys were uniformly distributed you would never use a varint encoding to store them because you'd stand a very high chance of encoding them into a field longer than a primitive integer. A varint can only hold 28 bits

Encoding an image as a repeated sequence of variable-length integers would obviously be a poor choice.

by shereadsthenews 7y ago
I don't know but how does complaining that it takes a microsecond to encode 256 random numbers lead to the conclusion that remote KV caches are unworkable? That's just a non sequitur.
27.
by shereadsthenews 7y ago
I think it's irrelevant. In fact the protobuf might be the best choice. If it was just defined as so: bytes key = 1; bytes value = 2; ... your overhead can be as little as 4 bytes and you can alias the memory of the key and

An interesting take. When borg was written the main machine class was dual-dual-core opteron. Now I imagine the typical borglet has dual Haswell or Skylake CPUs with I guess between 40 and 88 cores. Do you think (or do you have data that

Yeah, the only thing we can really learn from this paper is that the authors aren't very familiar with protobuf. Anybody who claims it takes 10 microseconds to decode a 1KiB protocol message is either intentionally constructing the wor

by shereadsthenews 7y ago
I have some real beefs with this paper. Their number about how long it takes to encode or decode a protobuf is wrong and misleading. It seems to be based on this benchmark[1] which encodes a huge repeated int32 stuffed with random numbers
