Weird. The Square readers we have in Australia support both chip-and-pin and contactless (+pin for purchases > $100). Were they only using the cheaper audio-jack swipe readers in the US? (Not allowed here any more)

I've been using Apple Pay recently, and one annoyance I had was that one store when I paid (for a >$2k purchase) didn't ask for my PIN... it asked for a signature. And then of course I was meant to present my card for verification. And I couldn't... what?

Knowing this about yourself is half the battle. Good for you for now trying to address it. I've had to fight off this tendency a great deal too. The effect of "pride" will always lead you to a fall, sooner or later.

Perhaps the best way to overcome pride is to study the neutralizer for it, humility. This as opposed to learning about all the many negative effects pride causes.

I respectfully disagree with you. Most people (in the US) do not care. I used to work for an adtech company which engaged with all sorts of third party vendors (like Axciom, BlueKai, etc) and every time I would explain my job to most friends or strangers, people often rightly assumed that shady data dealing is what was going on behind ads and services like Facebook and seemed not to care. There has been little appetite to change this until recently, and frankly only because of Donald Trump. No one seemed to mind the Equifax hack, and no one wants to change their lifestyle or stop using services they enjoy just to support privacy. Until a company like Google or Facebook gets completely hacked and some truly incredibly embarrassing personal information gets made public on a mass scale, I think that sentiment in the US will continue.
Works well. Folks are mostly honest, you’re going to meet in person eventually.
I have a fairly specific question - I'm in the process of migrating a large array onto another disk using zfs send and receive (6TB). It's been at it for about 2 days now. After the migration, I plan to destroy and recreate a larger array and send it back. If the pool is not being read/written to by anything else, am I safe? Or should I stop the send and receive and downgrade? Thank you for the hard work.
The odds that you could perfectly pull off such a stunt are very low, approaching zero asymptotically as time passes and scrutiny grows. For the thing to work everyone involved would need to be perfectly able to keep a secret and consistent with their stories. All of the forensic evidence down to carbon dating of dust particles would need to be consistent, and you’d need to foresee decades of developments in archeological techniques which might uncover your plot. The moment your scam is uncovered your reputation is irreparably destroyed, you become a pariah and your professional life ends. Given that it seems wildly unlikely to be an outright scam, although anything is possible.
I think these bikes miss the mark on two major fronts:

- Why do they need to be electric? Bicycles are phenomenally efficient, even for people who aren't in "good shape." In SF you can find routes around the really crazy hills. Furthermore, electric bikes reduce the barrier to entry for douches to "go cruising". Every day (NYC) I almost get hit by one of these things buzzing around. I'm sure these bikes are less powerful, but come on, exercise!

- Dockless. There is plenty of room for docks, USE THE ROADS. This video does a great job showing how inefficient cars are with space: https://vimeo.com/223171024. It's not right for a company to co-opt public space with their bikes. These should be designed into cities. It's not hard; make space.

Eh - you only have to read forums to realize that it's a lot more to do with the taxes.

I have heard more BS excuses from servers on forums: "The government demands we pay tax on these tips, even when we don't get them". No, the government recognizes you're in a cash-heavy industry, and would like you to document things. If you do, you pay tax on the tips you get, not the default amount. Quick way to get banned from said forums? Ask if they are sure to supply documentation when they get tips above and beyond that amount to the IRS.

They also like to claim that "20% is cheap, you should be aiming for 25%"... eh.
I'm kind of curious what the little blue system on the front page is. It looks very similar to a CuBox (speaking of; I'm kind of sad there are no iMX6 images), but with slightly different port placement.
Does this matter? We (not just IT people, everyone in the world) always lack the imagination of what could happen, and every time we're caught off guard by the creativity of malicious people. Sometimes a government is to blame, but eventually it's just us. Again, security is a process and a never-ending game of arms race. When you stop playing, they'll get the best of you.

Hey Jaye,

Although I wrote Full-Stack Web Developer right under my name I will add it to the about me section. I haven’t applied for any jobs yet. Updating my resume and LinkedIn profile for the first time in years to start the process this week.

I didn’t think anybody would pay much attention to what I did on my previous career so I abbreviated it. However it seems a good idea to provide these kind of details.

And I do plan to start blogging ;)

Good points. Thanks a lot for your help.

LVM can do snapshots and Redhat is working on its own hybrid storage management solution based on xfs called stratis[0]. Redhat deprecated btrfs recently. I don't think that means anything more than Redhat has lots of xfs devs and no btrfs devs.

You should be fine. The DMU that handles send/recv is unaffected as long as the snapshots at the source were not taken after 0.7.7 experienced an ENOSPC on file creation.
No?

And you're forgetting the double parking, bad parking, standing cars, building construction, street construction, etc. Streets of Manhattan are chaotic. Trust me when I say that there is often not any room for motorcyclists to filter past cars, especially not when bicycle lanes are present.

Not to be that guy, but I’m really starting to question the accuracy of dating techniques when they publish finds like this.

This finding is only significant because of the age, but have we ever verified our dating techniques over 5k years? 10k years? What’s to say that the hot desert sun and strange weather patterns, radiation or whatever couldn’t skew the dating and mean this bone is just some traveller from a mere 1-2k years ago.

It seems further unlikely that such a bone from, 85k y/ago as they say, would be so close to the surface.

Ftn In mechanical engineering we don’t ever “trust” the calculations until they are thoroughly validated with ie strain gauges. And more often than not we discover our assumptions were wrong. So I suppose a similar thing applies here in dating science, except, it’s impossible to validate for another thousand centuries. It seems backwards to hinge all our science on it when (AFAICT) it hasn’t even been validated itself!

When I'm very sleep-deprived, I tend to be better able to focus on the present, and not worry about ambient anxiety-causing topics. My mind has less resources to wander as much as usual. Between that anecdotal experience, and previous stories about sleep deprivation as a treatment for depression, I wonder if there's something to be set about forcing your mind into a single-threaded mode, to avoid the usual distracting worries.
Can't they do destructive testing of a part of the fossil using some isotope with a longer half life than carbon 14? It's described as being in a field of bones sticking out of sand so it's the only possible way it could have been accurately dated - no surrounding sedimentary rock formation to do additional testing upon.
I relate to your usage scenario, and my requirements are similar, and so are my frustrations with older filesystems: little or placebo protections against silent data corruption, lack of CoW semantics, pain of deduplication.

But on the other hand, over the years, I've heard so much FUD -- or underwhelming rumours that may-or-may-not be FUD -- about both ZFS and btrfs that have made me very reluctant to jump ship, and instead lean on an extensive suite of homemade processes and procedures that badly try to replicate subsets of features I'd expect a modern filesystem to provide. This is likely a Bad Idea, but my trust model right now can better stomach me losing data due to my bug, than someone else's.

I think what I'd like to see is widespread deployments, deployments-by-default, and better, persistent press and/or marketing surrounding *ZFS or brtfs, such that I wouldn't feel like an early adopter when using these filesystems. I'm actually glad Apple secretly wrote a filesystem with some of the same ideas, and deployed it to production on millions of (users') devices in the wild, because it raises the profile of modern filesystems and increases the likelihood that comparable alternatives will see more attention.
Ooh, good point with Wakefield, what a piece of work! The harm he did will almost certainly outlive him, so I guess that’s a legacy?!
I know HN is rather negative toward cryptocurrency in general, but for me it's fun. I run a small mining farm in my basement. It keeps my sysadmin skills sharp and more than pays my electric bill.

News sources are reporting the warrant was VERY broad.

So, now Mueller (through proxies) is applying more leverage, as expected, attempting to get yet another confidant of Trump in his snare. Cohn has reams of docs and provided plenty of testimony under oath - - now agents will examine all the docs they raked from the raid to determine if they can press the most common of all gambits: Lying to the FBI (or a court of record).
If they can prove this, then they apply elbow grease to Cohn to try get him to desert and testify against Trump in exchange for a lesser sentence. But now Trump smells blood and could actually push the nuclear switch option and give the apprentice battle cry to Mueller "YOUR FIRED !". Trump could also pardon everyone the FBI snares, that is, if he doesn't get impeached, which seems unlikely with precedent being Clinton's brush with impeachment where the vote came down along party lines (failed).
For the record. Yes, a lot of money was spent developing this codec. However, a lot of creativity and risk-taking was involved as well.

It was far from clear 15 years ago when xiph released Theora (aka vp3, ancestor of av1) that going up against mighty MPEG, with their enormous war chest from a decade of royalties, and dozens of patents (and the money to defend them) that success in the end was even possible much less assured.

It's really a wonderful story of the triumph of open source philosophy over the IP licensing model.
I think I've used the source code control system mentioned in the article. It was indeed a pile of garbage. Took a couple days of training in it, and the folks running the class kept telling us not to use certain checkboxes and features of the UI "or bad stuff will happen".
As far as I know, it has never experienced an ENOSPC error. It was mentioned elsewhere that a procedure is being developed to detect orphaned files that arise from this bug. Would it be a good idea for me to keep the original array around long enough to run through that procedure just in case?

I'm not an expert in archeology but from my understanding, we can gain alot of information from bones that could lead such a finding.

For instance, carbon dating and analysing the ethnic origins of the skeleton could lead you to say that you have an Australian (Australoid) fossil from 20,000 years ago.

If you found that in Northern America that would raise serious questions about where exactly it was found and if it was moved since it doesn't fit within any of our current understandings of migration patterns.
But you only have to encode once, or once per client type as opposed to per-client. And the more efficient decoding is, the wider the range of potential clients and/or the better the quality for a given amount of bandwidth.

I honestly can't understand why this would shock anyone with experience in engineering. As a senior developer, I'm vastly more able to realize ideas than I was even three years ago. I also know vastly more. I'm able to understand cutting-edge systems and language research that I couldn't before. I'm able to design systems quickly and more reliably. I'm able to separate good ideas from bad ideas more reliably. I'm better with people and managing my own ego, and therefore able to navigate interpersonal situations more reliably.

I'm also financially stable and have deep savings, so I'm able to take time off to pursue ideas more reliably.

After a few more years, particularly as I gain leadership experience, I expect to be even more effective.

Carbon Black is far from the only player in the space. Tanium, Crowdstrike, Trusteer, Cylance, Cisco AMP, etc.

The way these "next-gen" endpoint systems work is by doing a deep analysis of every file, and like you said, uploading the hash to a central server for faster processing later. Your use case is atypical for CB customers but I fully believe you're having these issues. There's a drawback to every kind of endpoint protection. It does seem that the more general population is worse off with traditional malware protection than CB, but your use case seems non-traditional.

I should note that I am not affiliated with any endpoint product and AFAIK the absolutely massive company I work for doesn't even have an endpoint product that competes in the next-gen space. I'm just a security consultant who sees a lot of Fortune 500 companies and notices the trends they set/follow. It's trending away from Symantec and towards Carbon Black/Tanium/Cylance/etc.

> the only way for a spectral flux (SLF) to be optimal considering its spectral luminous flux (LF) is to be entirely concentrated at ~550nm, laser-like.

Yes, that's correct. For maximum brightness given a limited amount of energy, you want all the light to be emitted at a wavelength matching the maximum of the eye's luminosity function. Of course, if the light is very bright, it will saturate your green cones, at which point you would want to stop adding 550nm light and switch to a wavelength that matches one of your other cones.

I am the developer who volunteered to develop the code to fix things. Anyway, there is no reason to avoid send/recv with 0.7.7. Send/recv will neither trigger this bug nor make it worse if it were triggered.
A disaster for enterprise perhaps. I use only a subset of features (such as subvolumes and snapshots and a little RAID 1) and have never had problems. With the way some people talk about it, it sure sounds like it never worked at all.
Did they really have to include strong crypto?

Most secure protocols negotiate a cipher suite. They just had to add the ability to do so, and maybe some placeholder algorithm using the maximum allowed strength at the time.
