Thanks. That book is a great resource.

You can try, but you realistically will never be able to convert all the finance/analyst type folks off Excel. Their workflows are too ingrained in how Excel does things (vbscript, proprietary extensions, even simple vlookup tables tha

I've been thinking about this too, but I believe that Vint Cerf's solution is not feasible. Or, rather, it's a typical technologist "solution" that only prolongs the problem. Imagine you're an archaeologist in

Let me clarify a bit: One of the things I love about Go is that I don't have to learn all kinds of conceptually heavy frameworks to get real work done. I read the stdlib docs and get to coding. I've also found that when I'm t

Generally speaking, Go is not a good fit for frameworks (which are meta-tools by definition). Implement the actual tool itself in Go, not a framework to build the tool.

Keep in mind that reads do not go through Raft by default, so it's possible to get stale data. They've added "consistent=true"/"quorum=true" URL parameters for GETs per https://github.com/c

I'm not surprised. I've never actually gotten replication groups and access control to work properly with MongoDB. So I gave up and relied on network/firewall-level security. I guess some people don't even bother with th

There are better, more reliable ways to do this than redis. NSQ for example, in a reactive (or log-based) pattern. Regardless, your goal should be reducing shared state as much as possible, since synchronizing it among distributed systems

TLDR: Adjust GOMAXPROCS if you want a speedup from multiple goroutines. http://golang.org/pkg/runtime/ "GOMAXPROCS sets the maximum number of CPUs that can be executing simultaneously and returns the previous

I have zero experience with rendering but I have never had an issue adjusting GOMAXPROCS for web apps.

I agree and share your cynical view of Agile/Scrum, at least how it's often used in top-down organizations. In my experience there are two factors required for a successful project: a) Developer autonomy sufficient to modify core

There exists a third party library called goamz which has been forked all over the place when people have needed to add random features not found in the original version. It works well but hopefully you don't need a set of features tha

You could do the same with LA. "Greater LA" also includes the Inland Empire, Orange County, Riverside/San Bernadino. Total population (according to Wikipedia) is around 18 million. I agree that you can draw the line arbitrari

Great article. I have the firm belief that Los Angeles is actually the largest city by population in the USA (as opposed to NYC). Due to an accident of history, what people colloquially call "LA" is still divided politically into

No doubt. "Big iron" for me is something like a $30k Dell R910 (pretty beefy for commodity x86). I'm guessing these mainframes go for at least an order of magnitude more per unit. A sibling post added some interesting facts (

In many ways I'm a hardware guy. I enjoy building infrastructure in datacenters from bare metal. Yet I can't think of a single use I would have for these IBM mainframes, nor even what they run (DB2?). IBM's product line just

Add to the list: - function annotations (allows runtime type checking via third party modules) - asyncio (not as easy to use as Go's goroutines but still vastly superior to the multiprocessing module)

My "citation" is my own experience managing infrastructure for several AWS-backed startups. I think public cloud services have a role and make sense in certain cases (particularly for very early stage companies), but I'm real

by bkeroack 12y ago
As have I. I'm not saying it isn't possible, rather that the performance pales in comparison to (and is much more expensive than) real hardware.

CPU-bound workloads are not particularly rare. Also, EBS is your only storage option for any data you might care about. 90% of the reason RDS exists is because I/O is so bad on normal EC2 instances.
354.
by bkeroack 12y ago
It's better, but only marginally useful for things like /tmp or swap. A number of instance types don't even support ephemeral volumes.
355.
by bkeroack 12y ago
My experience is similar. EC2 performance is mediocre in general and quite poor compared to dedicated bare metal. Disk I/O is abysmal (yes, even on "SSD" EBS).

In the narrowest sense your sentence is correct. Perhaps you mean that you think this can be expected on any computing hardware, which is far from correct. If all you've ever used has been public cloud services you can be forgiven fo

At the risk of being down voted, let me say that this is yet another AWS "feature" that is primarily a workaround for deficiencies in the platform.

My experience agrees with the general tone of the article (although I didn't dig as deep into the code as OP). I implemented an OpenStack private cloud for testing/QA purposes but never felt comfortable enough with it to migrate p

It means owning and controlling your own hardware. It's really, really nice to be able to reason about real hardware when doing performance optimization or deep bug analysis. If you're stuck in the public cloud ghetto there's

If your interview question has a correct answer, it's probably the wrong question.
