I found a nice compromise in Fuji's crop system. The cameras are about as small as can be while still retaining reasonable handling (having tons of mechanical knobs helps). My experience was that outside of some extreme special cases I

US appliance prices are ridiculous. I paid 689€, taxes inclusive for a top of the range 24" Bosch induction top. You could add an integrated oven and still end up below ~1k€.

That's not an option for cook tops integrated into the counter, which is the majority over here. But basically that is what I had in mind.

I think that's largely a function of how much the manufacturer is willing to spend on hardware. I have a Bosch Series 8 cook top and it has enough power levels and fast enough PWM cycle that I can't detect the pulsing even with a

The additional constraints are also what enable performance optimizations. And not the small ones, the ones that give orders of magnitude improvements. Whereas right now neo4j is slower for graphs than postgres, just with a nicer UI.

A similar product could be produced reasonably cost effectively with injection molded plastics and doing the unit adapted crossover in digital domain. I think it has not been done because the story of it being painstakingly manually crafter

It likely wouldn't be 15% with an 8-wide x86 decoder if such a thing would even be possible within any reasonable clock budget. So in that sense a fixed width ISA does buy something. Also, given that chips today are mostly power limite

Encrypting the volume the database is stored is pretty much equivalent in security offered to TDE and satisfies all of the security requirements that I have encountered. For field level encryption you should implement it in the application

Nightmare is bit of an overreaction. It's just a single command at the end signifying "Ok, done for now". It's not forced on users, the system works just fine if you don't do this. It just works better if you do let

It didn't have to be. If only there was some foresight into standardizing a marking system to indicate capabilities of cables and ports. And possibly reduce the number of options available based on educated guesses on use cases and cos

I did a set of benchmarks recently for multi-dimensional scientific sensor data. You most definitely don't want row per measurement in PostgreSQL, but you can get surprisingly good results where you store a block of results per row in

It makes no sense for AMD to try to compete on price while their market share is effectively supply limited.

There are plenty of manufacturers making glass fireplace inserts that are designed to be combined with a heat accumulating flue systems. Romotop or Hoxter are examples of fancier ones. The finished stoves typically are specced to retain 50%

I don't know of any database that supports multi column count. But even if one did, count(*) does not have the semantics that you would expect from that. If the semantics were equivalent to expanding the column list then count(*) with

What is the mechanism for this? From what I remember of signal processing, linear combination of waves of a specific frequency can only result in a combined signal of the same frequency but different phase and amplitude.

32" 4k monitor at a normal viewing distance (~30" seems like a good estimate without bringing out a measuring tape) is pretty comfortable for work at 100% scaling. At that distance 1080p video looks significantly worse when compar

Moiré effect is due to aliasing. If images are properly filtered (blurred) before sampling there is no moiré.

The trouble with VR video and Oculus Go is that 3-DOF has high degree of discomfort when you try to move and the world seems to move with you. There has been some interesting work on synthesizing new viewpoints using deep learning with rath

There exist other, larger ThinkPads that accommodate user upgradable RAM slots for those that need it. No product can be all things for all people. For example you can get the P1 with 64GB of memory. As someone who splits his work between a

In pg_upgrade documentation there is documented a way to use rsync to quickly replicate the upgraded contents of the new primary to replicas. So you would first move to upgraded base VMs running the old version streaming from old primary, w

If fsync is turned back on and a manual sync call is issued before considering the replica valid there will be no risk from this.

pg_upgrade would have worked fine given your requirements. Just using normal streaming replication to move database over to new systems and then performing an in place pg_upgrade there would be doable with most likely a couple of minutes of

I was really surprised at how well Timescales compression worked. It was pretty much comparable to best in class columnstores. Only the row-by-row query execution engine was holding it back. Perhaps something that future versions of postgre
