None of that is saying bad things about Solar City's balance sheet in the 5-20 year horizon -- quite the opposite.

You addressed my first 5 words and ignored my further 3 sentences to justify those first 5 words, here. Could you do me and readers a favor and engage the argument here?

No, he/she didn't say that and that's not true. We've oscillated a lot on the matter, between the gilded age, the new deal, the postwar years, and the reagan years into whatever the heck is going on now. QE definitely b

I'd limit your case to "highly-concurrent environments where want lots of shared, mutable state". There's always cases for some shared or global thing that you're transacting with, but I think 99% of code in highly

Ah, well that's super cool. Doesn't completely counteract what I was saying but that's interesting, thanks for the tid bit.

Compare the cost of optimally, expertly built STM-using code to, say, just assigning some byte values in a *char array. Instruction count? Cache locality? Allocations?!? EDIT: Oh, and isn't STM typically just a wrapper over immutab

by jbooth 10y ago
If someone is asking for mutability for reasons of performance and clarity, giving them STM is like a kick in the teeth.

A lot of American writers and even academics who should know better immediately reach for "communism" when describing China as if there weren't over 2000 years of confucian governing philosophy established before Marx was eve

Fortune 500 are all sitting on record amounts cash right now, they apparently see no place to invest it profitably. The thinking behind trying to pump up demand is that if people are buying more, the Fortune 500 will put that money to work

More like 3 tiers of support: Scala -- native API Java -- java wrappers for Scala API, slightly clunky but same implementation Python+R -- janky process involving forking a process and feeding strings back and forth between JVM and python&#

Don't know if you'll see this, but: If only one host at a time has access to a given virtual block device, there are some opportunities to buffer outgoing writes with a write-through cache. That might be the way to go if you expl

Well, good luck with it. Don't get me wrong, I'd love 1.5x redundancy overhead instead of 3x. But even if you have to downgrade to offering either replication or XOR, it's still a huge missing piece of the typical container

Ok, so that plus a little MVCC can make you consistent, but you've still got the read-many-to-write-one thing from the perspective of your block device interface, right? And block devices, if I'm remembering right, don't lea

by jbooth 10y ago
How? I thought you're exporting a block device, not a filesystem? You can't append to a block device, and certainly every filesystem out there expects block devices to be random-writable, right?
196.
by jbooth 10y ago
Yeah, but they have to read several data/parity blocks, and then rewrite all parity blocks plus one data block, for any write to a given block. This creates big difficulties for both consistency and performance, and fixes for consisten

Any bias in the article is probably about 4 levels of reporting away from Bezos. More likely that the author found various defense contractors being extremely available to chat, living in the DC area and all, and trying to get an article o

What triggered me was just throwing out "reed solomon" when talking about random writes. How does that work? We'll read from 5 places to complete your write?

"So" Google lost potential business for a while from people who wanted to spin up VMs rather than wanting to ship code to a proprietary execution framework.

If I recall correctly, it took Google a while to actually offer the boring stuff. For a while, you could get a Google Compute Engine but you couldn't just get a dang VM image, because Google knows better than you and you should do t

Sure, but duplicating Kafka? How many man-months did they put into building this, proving it out, and dealing with fallout from any bugs or production issues? What's the point of retaining an engineer who's doing nothing for the
206.
by jbooth 10y ago
Yes. Depending on use-case, of course, there's lot of places where scala is preferable to Java. A byte-shuttling service where performance is important, mutability reigns and expressiveness is irrelevant.. not one of those places.

People have been saying the same exact thing as you since 2008 though.. we're coming up on 10 years and no expected hyperinflation. I'd suggest we need to revisit the macro models that predict it, especially considering that commo

I think the most cutting criticisms of Scala are the ones that pointed out your exact quote here: "If you wrote a clean new version today, there's a lot you'd leave out" That said, the Scala community seems to be moving

Force isn't what keeps the US government in power, established norms do. If those norms were weaker, or if enough people were upset enough to upset the norms, you'd see how much force can do without all the softer stuff around it
