We're currently doing an audit, non-security audit though, but auditor salaries will probably not deviate that much. We hired a top-five audit firm and were billed roughly $400 per hour in total for two auditors (senior, junior) plus some work by the partner, mostly at the beginning and end.

The scope of their work of course is what drives the total cost, but a single full-time week would usually range $15-20k.

I'm not sure we've eaten at any other fast food restaurants with them! McDonald's tends to be very convenient on road trips.

In general, though they're adventurous eaters at home, they don't eat well in restaurants because they prefer that we are all eating the same thing. And booths are much easier to contain them in than tables.
> Since the advertising model isn't going to go away

There are plenty of people who would like it to, and personally I hope they win. With sufficiently widespread and robust use of adblocking technology, perhaps advertising will become sufficiently unworkable to go away entirely.
> There are some issues with McDonalds, but it is a pleasant user experience.

That's interesting, given that McDonalds purposefully designs it's restaurants to get customers in and out as quick as possible. The chairs are hard, uncomfortable plastic, the music is annoying, and the dining room is always set to some arctic temperature.

> Their power to do this or to forbid that is highly discretionary and essentially boundless.

This isn't true; the regulators are restricted by the law and by politics.

In the end, the power exists - political power is preserved - the only question is who controls it. For issues important to society, U.S. tradition is that power is allocated democratically. Americans take a vote; power is ultimately in the hands of the voters.

Every other potential authority is theoretically just as powerful and arbitrary, and usually in practice is more powerful and arbitrary (IMHO).

I agree about the risks; democracy is the worst possible system - until you look at the alternatives. What better alternative is there?
It's the same here in the U.S, bring your own or buy their plastic reusable ones. The locations I've been too sometimes had spare boxes you could use, but that was pretty rare.
You bag your own. Generally the cashier puts the scanned items in an empty cart sitting there for that purpose, then you swap your empty cart for the one with your purchases in it and wheel it over to a counter against the wall to bag or box them up - at the counter there is a stockpile of empty boxes that you can take.
Yes. We bag on our own. Also we have to deposit a quarter to use the shopping cart. And it seems these stores have only 2 or 3 employees at any given time.

You bag the groceries yourself in the U.S. too. The cashier puts them in a shopping cart which you take to a nearby long counter where you bag them. (They charge for bags but sometimes there are empty cardboard shipping boxes at the counter that you can use.)
Apache Groovy (around v 1.0 or 1.5) used to produce bytecode that could easily be decompiled to Java code, but since version 1.6, the bytecode generated was changed so it couldn't be decompiled with the tool I was using at the time -- I forget what it was, could have been JAD. I know the JVM situation has changed a lot since then, but that breaking change was just one of those many little things that put people off using Groovy for anything more serious than quick'n'dirty scripting. I wouldn't imagine it would be easy to write a Groovy debugger if the bytecode generated is still so non-standard it can't be decompiled to Java source.

Usually they scan items faster than you can bag them. The area after the scanner is very small and takes only few items so you have to move fast.

I saw below that US Aldi cashiers put the items into a grocery cart. That doesn't happen in Germany as you are expected to do that yourself.

Everyone has their own strategy of how to place items onto the line to slow down the cashier at just the right moment.

Someone might over-simplistically state: "fortune favors the prepared". Sure opportunity presented itself - and one might even call it luck - but in order to capitalize on it, it took Randy Brown's and his family's perseverance and intelligence to do so. Kudos to him and his family!

Some of the things mentioned struck a close chord with me. My parents are immigrants and - though they would have liked to help - they had no higher education nor any advice to provide me when I was doing things like choosing the college to apply/attend, filling out/submitting financial aid forms, figuring out how to pay for college myself, even choosing my major, let alone helping me with suggestions on my future professional career! I was born here in the U.S., so i was "lucky" to not have language as an additional barrier. And as other posters stated, being in certain geographic regions of U.S. is helpful...But still, navigating your way through some aspects of life without having sage advice from experienced people, and people who can help with things like careers, college, etc. is freaking really hard!

Again, congrats to Randy Brown - and all the Randy Browns of the world - for this kind of accomplishment. To echo @simonw's perfect statement: very inspiring story!

The issue is that nobody would ever do this because it's against their own interests. If one ISP charges per byte and you offer to pay the charge, you've deprived that ISP's customers of the incentive to switch to an ISP that doesn't do that (which you then wouldn't have to pay for) and given every ISP that doesn't do that an incentive to start, so that you have to pay for them too. And then the ISPs can raise their fees without having to worry about losing customers because the people paying aren't the people deciding which ISP to use. It's economic suicide. Which is why it's rational to presume that anybody who suggests it is in bed with the ISP, which is then the obvious antitrust problem.

But let's just put the final nail in the coffin here. Does the music service want to pay their customers $1 for every gigabyte of music their customers listen to? Fine, pay it regardless of what the customer's ISP charges for bandwidth, the same amount to any customer on any ISP. If doing that is profitable then it's profitable regardless of what the ISP charges the customer, it's better for the music service because it doesn't give the ISP any pricing leverage on bandwidth charges, and if paying the customer money to encourage them to use the service works for customers with per-byte billing then it should work just as well for customers with unlimited plans, so the proposal will earn them even more customers.

He was privileged to be a black man since this drastically improved his odds of getting into Princeton. It's not anywhere near as much of an achievement as you are making it out to be.

As of 2006, between 2/3 and 5/6 of black students in the top 25 schools are there only due to race.

http://www.jbhe.com/features/53_SAT.html

So with high probability, it wasn't that much of an achievement to get into Princeton.

It's certainly far less of an achievement than it would have been if he were Asian.

(If anyone has more current numbers I'd love to see them. I've seen more recent numbers on state schools, which suggest 23% of blacks are only there due to race. https://fivethirtyeight.com/features/heres-what-happens-when... But nothing at the ivy level.)

what's a good way to test the backups?

Here's a way to do it. You need to feel comfortable around the OS X terminal command line. You only rely on OS X's built in programs, so it's an independent way to check if your backup program is doing the right thing.

As root, I used to do something like this:

cd /
find -x \
. \
-type f -print0 \
| xargs -0 -n 100 -x md5 \
| sort > /tmp/src.md5

Then I would run the same type of script in the destination directory and diff the results.

There are some annoyances. E.g. (from memory) the ~/Library/Caches files aren't backed up, so they will be missing at the destination. I wrote some sed commands to first remove some of these from the result checksums to keep my diff's more manageable.

Instead of the above, I currently use a Python script that I wrote, that let me fine tune things. At the heart of it is (as root, of course) using Python's os.walk to traverse a directory tree. For each file I use hashlib.sha256 to generate a checksum. I also don't descend into certain directories. Etc.

Using a few Python scripts to generate and process the source and destination checksums allows me to, at the end, use a simple

vimdiff source.checksums destination.checksums

to quickly see the few differences that remain.

Keep in mind that the perfect is the enemy of the "good enough". Just using the basic 'find' (and not a custom Python script) is plenty good. I used that method for many years.

Many errors stick out right away. E.g. if you have 1,000,000 files checksummed in your source but only 250,000 in your destination, then you quickly know that you screwed up.

Based on your description it seems like we suffer (or in your case 'suffered') from the same condition. I've been suffering from panic-disorder since my mid-teens and it is only recently when I tried an MAOI that my doctor recommended that I've seen the condition lift a bit. There is some co-morbid depression but I believe that is a result of the anxiety and not the reverse. The MAOI is effective but my anxiety still flares up from time to time, and I've been thinking of other ways I can try to improve my state of mind. I'm not even sure how I would broach the subject of ECT, as I haven't experimented with enough drugs to know if they are all ineffective. However, these trials give me hope that in the future we will have better ways of dealing with anxiety / panic disorders.

> Looking at my wider family, this condition is so pervasive ... and inherited, it's not even funny in all the ways it wreaked havoc on people's lives in many ways. Glad I caught a break.

I agree, it is quite sad. Like right now I'm certain that my father is depressed although the reasons for this are somewhat interconnected with real life events like unemployment, loss of loved ones, etc ...
I read the Wikipedia page but didn't get a great deal of information. From what I gathered, they decided to use a structurally/mechanically unsound abandoned salt mine as an 'experimental waste dump', and now there are concerns that if the mine floods, nuclear waste byproducts will get into the ground water? You're probably more acquainted with the issue so perhaps you can fill in the holes here?

At any rate, shutting down all German nuke plants because of something like this is akin to shutting down all coal mines because someone held a BBQ and accidentally started a fire.

Power to the user is one aspect of personal computing. But with the rise of mobile and now IoT, the user has also become (increasingly) a 'consumer', and thus the software and hardware are getting more and more locked down. Hardware and software manufacturers will sleep easier at night when their products cannot (or can only limitedly) be modified.

I think the writing is on the wall. Computing devices will split into two diverging branches: one tailored for limited configuration and aimed at media consumption and use by non-tech users, the other providing (hopefully) full freedom to modify, aimed at IT co. and interested hobbyists. It will be quite some achievement if mechanisms to increase vendor control aren't increasingly integrated even into the devices in the second segment, as things like Intel ME/UEFI Secure Boot show.
Yet, a nuclear plant, at a river that frequently floods in autumn, with not-working emergency generators, is in quite a risky position, don’t you think? It’s about the same risky position Fukushima was in.

And most German plants are like that.

Then add the fact that German inspections are a corrupt business regarding nuclear plants, and that the nuclear waste storage was a huge disaster polluting tap water for a large area, and you can see where the problems come from.

The original story I heard was that it encouraged people to stop using images of text on the web (which used to be a common way to get custom typography in pages). The images of text are hard to index and search because they would require OCR and would lose other possible semantic information that might be present in a textual page. So Google hoped that people would choose to use these fonts and then represent textual information as text rather than as an image. It seems to have worked!

Because it's a HN comment, not a scientific study on exactly what the best methods are. Sheez! The point is: if you spend some time thinking about it, you can probably find something that works 'ok' even if it's not perfect, thus 1) allowing supersonic flight and 2) internalizing the cost so that the market functions and there's some consideration of the costs to people in the flight path.

Excellent post. The post doesn't detail a problem with Postgres per se, rather the author uses plain language to explain Postgres' TLS connection mechanisms and how they are applied in AWS and Heroku RDBMS services.

When quickly iterating on software, I must admit I don't always consider configuring a root cert for the db. This nuanced look at Postgres' security options gives me much to consider for real production work.

tl;dr: configure a root cert for your Postgres db and use verify-full in your connection string.

> Now the cynical would point out that standard pen testers would have found that, and maybe they would, but the speed at which a contractor could find these issues and then see the full breadth of the surface compared to pen testers was great.

I consider one a function of how you are employed and the other a function of role. IE the two overlap and are not directly comparable.
I am not a specialist but the current situation looks complicated and not because of waste disposal but for financial reasons and long term planning issues. Areva, the main civil nuclear actor, made a couple of very bad (and shady) decisions, lost a lot of money, and is currently being restructured and partially merged into EDF, the historical energy French provider. Still they decide to keep betting on EPR power plants and engage a lot of resources in a new Hinkley Point EPR project. None of which have been finished yet. At the same time, inquiries reveal deficiencies or falsifications on quality assesments on supplied parts. The gravity of these is not clear yet. Finally, budget are tightening and plants arriving to their initial end of life dates are being requalifed for a decade or more.

I do not think relying so much on nuclear energy was a bad move but it should have been a transitional thing (to renewable energy, fusion, anything else?). And it requires good forward thinking, commitment and the kind of leader we have not had for decades.

Finally, the EPR looks more and more like a big mistake. Smaller designs might have been more successful and offered more agility in time of crisis.

Moving the antitrust problem into the FTC's jurisdiction instead of the FCC's doesn't make it go away.

Also, you're trying to have it both ways. You're also asking what the difference is between if the music service does it and if the ISP does it. The difference is that while both are bad the FCC can fine the ISP for doing it.
> Exponential growth doesn't happen in one discrete operation, friend.

Correct. In fact, it simply doesn't happen at all in a category like medical research spending.

Even if it did it's not likely the returns to that spending would grow exponentially.

But to humor you, by what mechanism do you think medical spending in the U.S. will grow from its current $95bn per year amount to $9.5 trillion?

Is your assumption that basic medical research will grow to consume 57% of the country's GDP, or do you anticipate growing the size of our nation's economy by approximately 50% to accomplish this feat?

Assuming you've got that sorted, who do you think should get the $9.4 trillion dollars in additional medical research spending you propose?

I also dont blame McDonalds as a company. Like any other restaurant they're forced to strike their own line between quality of ingredients vs price. Like any other restaurant they must pander to what their customer base wants.
