I think this is largely a non-issue now due to spectre mitigations. e.g. Chrome is enabling site-isolation by default which would run the new page in a separate process anyway. I think the other major browsers are also doing something simil

The problem is that clients won't be supporting 103 for a long time, I would guess it'll be 3-5 years before you can realistically push the 103 to a browser and I don't thank any currently support it. It's also not a par

In my example there would be only a single connection from the client, to the CDN edge. The CDN is acting as a reverse proxy for the main request and pulling Link headers out of the response(s) to decide what static assets to push to the cl

Crystal bears only very superficial resemblance to ruby. What makes ruby unique is meta-programming and it's object model neither of which Crystal supports in a remotely similar way.

I assume that MikusR was talking about the i7-8650U. Apple doesn't down-TDP the processors in the MBP. I don't know where this idea even came from and it's trivial to prove it false.
319.
by mbell 9y ago
i7-8650U is rated at 2.1Ghz @ 25W in it's TDP up config, so running it at 20W may get you 2.0Ghz instead of 1.9Ghz. But this doesn't tell the entire story either. Modern processors are constantly adjusting their frequencies across

by mbell 9y ago
That seems to depend on the task. The highest end CPU available, even the 15", is the i7-8650U which is a 1.9Ghz @ 15W part. This is also how they pull off 17hr battery life, they are putting an ultrabook processor in a 15" laptop

There are a few SLS printers that are approaching home/SB use pricing, <$10k. I don't think CO2 lasers are that expensive to build so I would imagine pricing can drop a fair bit if the volume gets there.

I don't see why FTP is any more valid than HTTP for this. Uploading from the browser directly to S3 isn't difficult. You can support resume and whatever auth strategy you want as your backend generates the signing key.

Ruby does something similar, but all Fixnum (native sized) values are 'fixed objects': a = 2**62 - 1 b = 2**62 - 1 a.object_id == b.object_id # true a = 2**62 b = 2**62 a.object_id == b.object_id # fal
