I had a wonderful Heisenbug once.

The machine was several hundred thousand £s worth of lasers, optical table and stepper motors moving a stage that must have weighed half a ton. The purpose was to print digital holograms, line by line, on glass plates. Between each line there was a delay of some seconds, during which time various calculations took place; even the smallest 3"x3" holograms took half an hour to print. Larger ones could run overnight. Once printed, the (expensive) plates needed another half an hour of darkroom wet processing, after which they could be briefly viewed (the image disappeared again until the plate was completely dry - uneven shrinking destroys the interference pattern).

The byzantine hardware control software had been written long before my time - my job was merely to write the imaging software that fed this machine as it ran. There was an elaborate startup procedure to follow, and just before you'd hit "start" you'd run my little C program, which would synchronise with a timing signal from a serial port. Then, as the stage whirred back and forth, it would feed images to a little display - 30 Hz, pixel by pixel, line by line.

One day, just as we were getting confident of the rhythm of operating the machine, a larger hologram came out "back to front" in a strange way - one of the parallax axes was reversed. Perplexed, we carefully tried again with the same file - and it came out fine the second time. Unable to reproduce the issue, the matter was dropped.

Some weeks later, just as our confidence had begun to wax again - boom. Another inverted hologram. Another large plate wasted. Another careful investigation, another failure to reproduce. A Heisenbug!

This continued happening, off and on, most vexingly - and of course, never when I was there, and only with the larger, more expensive plates. Eventually one day I came in and it had happened again, and this time I noticed something peculiar - the hologram had finished printing, but my little C program was just sitting there, waiting on seemingly the last line, for a timing signal that would never come. And the light began to dawn.

My C program had the basic structure "buffer line, wait for signal, display images, go to start". It turned out that what was happening was people were hitting "start" too soon after launching it, before it had had a chance to properly buffer the first line. It thus missed the "start line" signal of the first line - which caused it to print line 1 as line 2, line 2 as line 3, etc. And because it was a rastering stage, this meant that every line was printed in the opposite direction to what was expected.

The really treacherous thing about it was, it only manifested when I wasn't there because I knew instinctively to allow the program enough time to buffer. It only happened with big, expensive plates because they had longer lines which took longer to buffer. And it only happened at all when the operator of the machine was sufficiently confident, or in a hurry, to perform the final two tasks of the checklist within seconds of each other.

The fix? A note in the checklist.

I miss the job, but I don't miss debugging that darned machine.

Jobs do not fill magically. Most of us is too busy with work, side projects or family to track if your amazing company have new hot opening.

Above average people are usually treated well in theirs jobs. If you want to hire them you need to actively approach and lure into applying. Even then, they will not bother to refresh algorithms questions for whiter-boarding.

Below average people are looking for jobs because they are on PIP or they have toxic relationship with management or they will never get promoted in current role and need to change jobs.

If, like me, you read that quote and wondered what exactly the song is about, then here is another fragment of the quote that might help:

They don't realize that 'Street Spirit' is about staring the fucking devil right in the eyes... and knowing, no matter what the hell you do, he'll get the last laugh...and it's real...and true. The devil really will get the last laugh in all cases without exception, and if I let myself think about that to long, I'd crack.

One would think in 2017 there would be some kind of solution that allows to track all certs in the org and raise alert well before the cert actually expired (of course, nothing can prevent admins from ignoring the alerts). But given how many cert screwups happen around, looks like it's not happening. Maybe somebody should create a startup doing this? ;)
The "PDF language" itself is not that complex per se and ofc. executes in a VM. PDF also allows to embed various stuff, including Flash and JavaScript, which both execute in a VM as well.

No PDF reader was supposed to just execute x86 instructions from a PDF file (wouldn't be very Portable, would it?), although many PDF readers had enough security issues that it's an arguable viewpoint.

Docker has taken the direction of a loose collection of tools tied together by an integrated interface. So you have the choice of using the platform as a whole, or standing up your choice of individual components on their own, without any dependency on Docker.

Based on your comment, you're probably not the target audience for the platform. I recommend checking out some of the components to see if they meet your criteria of simplicity.

A few examples:

https://runc.io

https://containerd.tools

https://github.com/docker/swarmkit

https://github.com/docker/notary

https://github.com/docker/infrakit

https://github.com/docker/hyperkit

We are continuing the work of carving out more and more usable components from the platform.

The frightening part about your post is that you might not even be trolling.
>You assume now that metric is conclusive because it fits your conviction.

No, you're now walking back your claims because the one metric you have quantified doesn't fit your conviction. At the time you claimed that by simply looking at the feed you could tell it was biased. You initially made the claim that the lifeatgoogle twitter was related evidence to your claim that google wasn't interested in hiring men anymore. I'm not silly enough to claim that a brief perusal of a twitter account can be extrapolated into a claim about a company's hiring strategy.

Thanks to your quantification, we have some evidence to suggest the lifeatgoogle twitter is fairly representative of population demographics along gender and racial lines, at least in the US. I don't see the data as conclusive of anything more than that.

Then they just use what the military call an "anti radiation" method of target homing.

No one is assuming documents are safe.

Every now and then you'll see some av or email provider like gmail block PDF files in masses often ones that were generated by a very specific program or process and very often because their internal post script was iffy.

I disagree. I think it is in the benefit of the platforms themselves (e.g. Twitter) to promote equality, tolerance (to different points of view) and freedom of speech, especially to those they disagree with (e.g. Milo). IME it's the "tolerant liberals" that don't even try to engage in intellectually vigorous debate (they'd rather protest, ban, shout, fire their oponents, or call them "hate-mongering trolls").

Another cheap defence for the drone is simply to change direction or altitude radically when an appropriate sensor detects an incoming eagle. The eagle is in a dive and has limited maneuverability.

Or, if the eagle does grab you, simply explode (as already stated elsewhere) and take out the defence, while one of your swarm buddies completes the mission.

Assuming that trackers have this habit-building effect: While we then would expect the effect to have have been larger if they'd handed out the trackers at the beginning of the study, some participants should have benefited from this effect even mid-study.

One hypothesis here is that the trackers provided a frame of reference that anchored participants to some goal like 10'000 steps daily while the participants who had less direct feedback were free to expand their goals as their fitness improved. Some things seem much more arduous to me when I track progress while doing them.
Pizza places in the UK typically give a discount for collection from the shop, which presumably accounts for the delivery cost.

>If the product is inherently viral, you don't need to market.

Surely the "inherently viral" aspect of a product is a marketing strategy? (albeit one that is open to optimism)

This seems to be a larger part of the problem; one developer's marketing strategy is another's "just build it this way".
Then you will quite possibly be denied access simply because they cannot harvest your social media profiles for profiling.

Kennywinker's comment is right that technological cleverness won't help much here. Carry no devices, and you are suspicious and/or non-cooperative (unless you are over the age of sixty). Carry devices with no data, and you are suspicious and/or non-cooperative. Carry devices with carefully prepared fake profiles and datasets and you might pass muster… or be regarded as suspicious, non-cooperative, and/or actively resisting (if the border agent judging you suspects he is seeing fake data).

I wonder how they are trained to react to people without social media accounts.
Marketing is important, however more important is to build in a viral loop into your product, that for every new customer x>1 new customers are contacted.

This is how social networks work, invite your friends systems, etc.

However, even then marketing is still important. But too often marketing is seen as: Spend huge amount of money on ads.

No: marketing is market research, choosing your target audience, branding, image building, tone-of-voice etc.

I sell B2C software with a subscription of 1.99€ per month. I have 7,000 active users. I get 5-10 emails per day max.

Before I charged money for my software, I was afraid of the overwhelming flood of customer support requests. Except they never came.

> even one short email enquiry would wipe out a dozen sales or more (if you put a monetary value your time)

Per email, yes, absolutely. Sometimes I take 20 minutes to answer a more complex email. But since I know that I don't receive more than 5-10 emails, I take the time and this person might recommend my software to other people, because of the great support.

An easy way to mitigate customer support is to have FAQs and lots of written texts on the website. Most people prefer to help themselves I think, because its faster.

Sometimes I wonder if this is a mentality thing. My customers are all Germans. Maybe US customers are faster to send a short email than browsing through FAQ.
pfSense is good, I've used it before.

Ask HN: What to do with my Android app users
I have an Android app with around 800 users per months and I don't what to do with it. Any ideas?

The app is: https://play.google.com/store/apps/details?id=com.ym705.makeawish&hl=en

It's a simple app where people can make a wish, they type their wish (less than 200 characters), select an image that fit with their dreams and that's all.

I initially developed the app to practice with Firebase, and once the user made a wish he can explore the other people wishes and like them (act like favorites).

I have small ads on the app that bring few money and I was wondering how could I change this ap to a true income and also make it useful....

Maybe selling card/magnet or something with the wish printed?

Selling lucky charm that fit the wish type?

Thanks everyone!

Based on your quantification, there's now more evidence for the claim that you perceive an unbiased sample of people to be biased towards minorities and women, than there is evidence against that claim. It seems like you're struggling to reconcile this bias with the quantification of it.
Custom search has large maintenance costs--a lot of effort which really isn't interesting for any developer to work on. And apparently companies aren't willing to pay enough to overcome that. I don't think Google has any obligation not to shut down products.

Which is the problem in the first place.

Why are we taught by people to tip some personell and not to tip others?

Because the first group has a very low income. That's why.
Because corporations cannot be trusted to treat their people nicely. That's why.
Because the first group usually works hard and shows effort, while the others don't. That's why.

I don't mind to tip when someone has done an excellent service, but i always try to make sure my tip goes to that person directly and not some weird strange thing like a jar or a fund the corporation came up with.
