dbenhur··on Okta’s Investigation of the January 2022 Compromise
"Prior to Okta, David was the Senior Vice President and Chief Security Officer at Symantec" So, his prior experience is as CSO at a company who's principal business is selling fake security products. Ho, boy.
dbenhur··on 911 emergency services go down across the US after CenturyLink outage
If someone dies due to inability to summon emergency assistance, this will truly be a post-mortem instead of a badly named incident retrospective.
dbenhur··on At Blind, a security lapse revealed private complaints from tech employees
You can read plenty of behavioral signal from how candidates interact with interviewers while solving hard technical challenges. But many companies don't really invest much into training interviewers how to effectively interview and gather useful signal or calibrating their evaluation to the goals and standards of the organization.
dbenhur··on Amazon move off Oracle caused Prime Day outage in one of its biggest warehouses
coe.amazon.com if you're inside. Larry must have paid for this article. Some things it doesn't say: Large database migrations are hard -- especially so when there's been many years of accumulated dependency on the prior data store/model. Amazon conducts a lot of CoEs -- I suspect more than 1000/yr. Hundreds of prior CoEs implicate behavior of relational databases (and particularly Oracle) at scale -- there's a reason Amazon has an expensive multi-year program to get off Oracle.
dbenhur··on A Spectre is Haunting Unicode
Wikipedia remembers: "The Scroll Lock key was meant to lock all scrolling techniques, and is a vestige of the original IBM PC keyboard. In the original design, Scroll Lock was intended to modify the behavior of the arrow keys. When the Scroll Lock mode was on, the arrow keys would scroll the contents of a text window instead of moving the cursor. In this usage, Scroll Lock is a toggling lock key like Num Lock or Caps Lock, which have a state that persists after the key is released."

dbenhur··on The Peril of the Laptop Sticker
I agree, and I work to preserve the historical timeline... The seed for my next pristine macbook: https://photos.app.goo.gl/h3Fx2DEe5cD7Mkqw6
dbenhur··on What I Learned Working for Steve Ballmer
Incognito window is your friend
dbenhur··on Amazon EKS – Now Generally Available

dbenhur··on The Cult of the Root Cause
Yes, root cause analysis and corrective action should only to be done with Cook's insights in mind.

"Post-accident attribution to a ‘root cause’ is nearly always wrong." "Post-accident remedies usually increase the coupling and complexity of the system. This increases the potential number of latent failures and also makes the detection and blocking of accident trajectories more difficult."

How Complex Systems Fail is short but loaded with value; if you haven't read it, go do so now!

dbenhur··on Another reason why Docker containers may be slow
Not only that, but glog authors observed the overhead of frequent fadvise and added rate limiting almost a year and half ago. https://github.com/google/glog/commit/dacd29679633c9b845708e...

+1 perf. -1 stale library use. -1 misdirected learning

dbenhur··on OpenStreetMap Is in Trouble
> "you'll find no statues of committees"

Well, maybe one or two: http://theenchantedmanor.com//wp-content/uploads/2016/07/Nat...

dbenhur··on Meltdown Update Kernel doesnt boot
Most vehicle recalls are not of the form: return your vehicle, we give you a new fixed one; but rather: bring your vehicle to one of our dealers and they'll perform some action to repair the defect.

The later is pretty analogous to issuing firmware and OS patches to mitigate the flaw.

dbenhur··on Is abstraction overrated in programming? Chess, interviews and OOP
If you aren't argu^H^H^H^Hdiscusing with the interviewer, you're doing it wrong. If that results in unfavourable evaluation, that's good data for you whether you should take that job.
dbenhur··on Detailed Financial Histories Exposed for Thousands
No. The exact opposite, in fact.
dbenhur··on Amazon Neptune – Fast, reliable graph database built for the cloud
Janus is a fork of Titan, BTW. The core Titan devs got acquired by Datastax and redirected to their graphDB offering. Titan stagnated, then got forked as Janus under the Linux Foundation.
dbenhur··on Slack is offline
Yeah and they've had service degradation and availability issues long before Slack also. ;-P
dbenhur··on Wind Energy Is One of the Cheapest, and It's Getting Cheaper
You make no sense with your statement about depreciation. Depreciation is expense which lowers profit. It's the accounting mechanism we use to spread one-time capital cash outlays over the service life of an asset so as to more realistically calculate profit and loss on an ongoing basis.
dbenhur··on I’m 35 and I may suddenly have lost the rest of my life
If someone stabbed you in the rectum, the bleeding is explained. You should still probably get it looked at.
dbenhur··on Linux Load Averages: Solving the Mystery
No, long time past to discard it. Measure what you actually care about, not some synthetic, poorly understood "load"
dbenhur··on Ageism is forcing many to look outside Silicon Valley
> Over the last 8 weeks leading up to defense we still worked our normal FT employment and completed revision and defending our individual dissertations while averaging 5-7 hours of sleep a week.

Cool story bro, but utter bullshit. People who do that die, they don't have the mental capacity to defend a dissertation. Eight weeks at 1 hr/night is not something humans can do.

dbenhur··on The Google Memo: Four Scientists Respond
Alternatively: his membership in a privileged class is unlikely to grant him especially accurate insight into the experience of individuals in less privileged classes, and more likely to reinforce his bias to justify his own privileged position.
dbenhur··on A theory of modern Golang
It's the method of DI known as Constructor Injection. https://en.wikipedia.org/wiki/Dependency_injection#Construct...
dbenhur··on Be Careful with UUID or GUID as Primary Keys
And people act outside the bounds of the law. SSN seems like a good natural key candidate, until you discover some of the people your business interacts with are illegal aliens.
dbenhur··on Comparing Bandwidth Costs of Amazon, Google and Microsoft Cloud Computing
Restaurants operate on pretty thin margins. You're confusing the cost of raw materials with the cost of prepared and served meals.
dbenhur··on “Users will only be able to view patents via HTTP. HTTPS will no longer work”
I know! I takes at least three rewrites to make it that terrible.
dbenhur··on Brains Sweep Themselves Clean of Toxins During Sleep (2013)
My cats figured this out quite a while ago.
dbenhur··on Fact Check now available in Google Search and News
Curious you drop the adjective "overwhelming" in your quote and confuse scientific theory with hypothesis.

https://en.wikipedia.org/wiki/Theory "In modern science, the term "theory" refers to scientific theories, a well-confirmed type of explanation of nature, made in a way consistent with scientific method, and fulfilling the criteria required by modern science. Such theories are described in such a way that any scientist in the field is in a position to understand and either provide empirical support ("verify") or empirically contradict ("falsify") it. Scientific theories are the most reliable, rigorous, and comprehensive form of scientific knowledge, in contrast to more common uses of the word "theory" that imply that something is unproven or speculative (which is better characterized by the word 'hypothesis')."

dbenhur··on Summary of the Amazon S3 Service Disruption
> One would only actually test the backups about twice a year just to be damn sure they are still resulting in restorable data.

Nope. Nope. Nope.

You test every backup by automatically restoring from it in a sandbox and verifying its integrity and functionality in the restored state.

Backups are worthless unless verified for their intended use of recovering a functioning system.

dbenhur··on “CPUs are optimized for video games”
Yet Intel sells essentially the same microarchitecture to both
dbenhur··on What Marissa Mayer Brought to Yahoo That Can’t Be Bought or Sold
This right here. Saving Yahoo was impossible. If I had been an investor I would be quite satisfied paying the CEO $200M to secure $12B increase in valuation.
