Entity Framework in .Net is very easy.

The logic for migrations is suprisingly simple:

- A new migration will normally create a file with an Up or Down method and a "timestamp" + "description of the purpose of the migration" ( eg. 20191031_080603532_add_tags_to_contacts.cs )

- Every migration, when run on the database will create a new entry in eg. the _migrations table . Some will store the PreviousContext which is a hash of the CurrentScheme before the migrations.

If the application has a live check on startup. It will check the hash of the current db schema, compare it to an entry in the database.

Check if that compares to the latest.

The latest is the latest "migration file with up or down". It will execute all newer once according to the timestamp. Untill the latest one is executed.

A tool also contains a "TargetMigration" for development purpose or for reverting a database back to a previous state.

Every Up or Down migration is run inside a transaction. If it fails, nothing is stored.

There is also a way normally to do a Seed of the database, after the migration is run.
But this could be added in the Up or Down method.

PS. All other methods untill now were bad.
I really like this analogy. The question you were responding to has been asked - in one form or another - so many times on this thread that its clear that those developing software and business tools are completely out of touch with users and power users of those tools.

This. Its interesting to read this thread mentioning DB and systems issues that are solves in Oracle APEX. We built an ERP system for a oil&gas client, including in the requirements, apps for monitoring gas values at the plant, by simply connecting to the mesurment equipment API. All that on Oracle XE, free version that comes with APEX. Three weeks to build apps, five months to implement in the company. I'm thinking software is not the problem, its people, politics in the company, resistance to change, really everthing but tech. We're solving business problems, helping the company cut costs, increase speed and streamline processes. Tech is a tool - there are so many other obstacles to solving problems other then tech. Thanks for mentioning Apex, and Oracle, in a thread about DB-s that fails to mention the company building databases for 40 years, that run for instance at CERN, to name but one.
Weird, because if I were to create a list of everything ranked by how confident I am that the listed item exists, consciousness would be at the very top by a wide margin. Everything else could just be a nice illusion (e.g., brain in a vat).
Being self-motivated is actually incredibly difficult. Just ask any PhD student who has hands-off supervisors. Learning to chase your own goals independently is a skill you have to cultivate. You need to learn your weaknesses, what tricks you can employ to get working, and what you actually care about enough to achieve.

For me it sounds more like judging by past success. Just because someone successfully built a DVD business doesn't mean they cannot help to build a streaming business. Excluding people who were successful with "old" technology usually just leads to age discrimination.
I have not actually seen it (and I'm not the OP), but I have been told by French farmers that geese do willingly and even eagerly run up to get the tube inserted so that they can have the food force fed into their gullet. At least with the few farmers I've talked to about this, the tube was not inserted permanently (these were very small operations). Having never actually seen it, I don't have any understanding of the discomfort the animals face or the extent to which these reports are true. But neither do I have reliable information that it is not true.

One could certainly make a case for banning animal slaughter, but I suppose it would be practical only after we have good meat substitutes.

But in the meantime we could perhaps ban wanton cruelty such as Foie Gras. I'll add veal too to the list now.

One class I was taking (ToC using Sipser), I forgot to turn in the first two homework assignments on time, so I didn’t turn them in at all. Then I had to make sure to get perfect scores on the rest of the homeworks and exams to get an A. I wound up getting 100’s until a 98 on the final, so I visited the professor’s office at the designated time for questions on the final and asked what I got wrong. After he explained what I did wrong, we got in an argument about whether I should get points for the first two homework assignments, until I relented and accepted that he could give me points for the software part of the assignments without him looking at it, so he could give me an A.

On the other hand, when working as an undergrad teaching a Calc II recitation, I had a student miss a quiz I was supposed to administer, because for no reason, he just didn’t show up, so I let him meet me later that week and take it in front of me. My goal was to help him succeed, because getting a zero would really suck. I don’t think it violated the integrity of anything. He wasn’t falsely getting certified as having learned calc II.

I think most teachers are willing to do things like this if it’ll make the grade a more accurate representation of the student.
Thanks. Almost all of that makes good sense, and it's pretty clear that optimization kept working so they just kept doing it. I wonder how much farther it will go.

So you can find a limit. What if Barcelona does not want to be in that new country (and they don’t)? Will the borders of that new country inside which you start counting votes include Barcelona against their will? What freedoms do people who want to stay with the "original" country get? They suddenly become the oppressed minority. How many splinters is too many?

You object to the “dictatorship” of democracy in Spain but the plan is do do the exact same at a smaller scale in the new country to a newly created minority. The reason we’ve had the longest period of peace and prosperity in Europe’s history is that the rules are as they are now and they're the best compromise. Any “improvement” you want to get for yourself comes at a major cost for everyone.
> Further, some of the most expensive schools are some of the worst schools. I don't think we should be paying an unlimited amount of money for the same education. If the University of Pittsburgh can deliver results much better than USC (I'm not saying it can, this is a hypothetical) -- I don't think you should be able to get $70k a year to go to USC when you can study the same thing with better results at Pittsburgh for $20k.

But in France all the good universities are the public ones, and they are all roughly the same price (e.g. the Bordeaux one is roughly 250€ per year for undegrads and 500€ per year for graduates -- or 15€ if you have a scolarship).

> I also don't think it's a good idea to give someone like me a free college education. I make $400k a year. I can pay for it my fucking self if I want to.

50% of the people in france make under the median salary which is around 20150€ post-tax per year. Most people "couldn't pay it for their fucking self" (and were you making 400k$ when you were 16 y.o. which is the age you could start university if you're quite good and skipped a class or two ?)
I agree that would be the smart way to do it, but that would at least double the scope, probably more, since orthogonal area is a cosine function. There's also oblique reflection to consider.

Carl Sagan hypothesized a little about this in his 1985 novel Contact.

Years before, he had invented a module that, when a television
commercial appeared, automatically muted the sound. It wasn't at
first a context-recognition device. Instead, it simply monitored
the amplitude of the carrier wave... Before there could be any
coordinated response from the television advertising industry,
Adnix had become wildly popular.

Posting under a throwaway account.

This is story I actually know something about. I knew Shane personally and attended many BBQ's with him and the various other people that made up the explosives team.

I have for obvious reasons not had any contact with him since the incident.

I can even provide what I am very confident the reason for why he did it. He fully knew what he was doing, and indeed the reason was for money. However not for selfish reasons. A captain salary is not that fantastic in the army and his wife at the time, whom I suspect he is separated from now liked to live fancy. In fact I am 100% confident it is because of her that he did it. Probably without her being involved, but I cannot be sure of that. I do know she overextended their finances which would have been a good motivator.

Any claims he made to forget destroying them are a horrible attempt at deception to reduce his sentence.

For what its worth he was ostracised from the explosives community over this. It was a very small group of people, and Shane's appeals to have them speak on his behalf were ignored by them all. The group is very tight and for one of their own to betray was seen as a massive abuse of trust.

Honestly I was very sad to hear it. Selling out your country for the low amounts he did is such a sad thing. I don't think he needed to be in the super max prisons he spent his time in as I don't believe him to be a dangerous person. Certainly a very stupid mistake, but not a dangerous person. I suspect most of his being incarcerated in such was as a message. Personally I remember him as a fun person at a party enjoying a few beers and telling amusing stories of which there were many.

As for if other weapons are missing. That is possible. Shane was tasked with destroying them. Its much harder to steal from stores due to them being tracked quite well but those to be destroyed are much harder to keep track of. Usually there would be several people involved to help avoid this sort of incident.

> But with sane zoning and construction standards and a cap, you're inducing more intensive development

Your hypothesis assumes that increasing the potential revenue by square meter has no effect attracting Urban development projects.

It seems obvious that if it's possible to increase intensity then being able to generate more income per m² only helps put together a valid business plan that increases supply.
What rate of misjudgment would you be ok with?

I think cases like George J. Stinney's prove that it is not a reliable process. Best is to avoid any judgment when it is not necessary, like limiting freedom of expression.

Vidangel got into trouble because they were a for-pay streaming service selling copyrighted content. Clearplay is just an add-on for Google Chrome which downloads edit lists. They also sell a DVD/BluRay player which uses their lists.

I wonder what Clearplay found to censor in Disney's Toy Story 4, Aladdin, Paddington, and Frozen.

Sorry but you are comparing apples to oranges. The EU is not a country, it is a club of countries. The EU doesn't and never will have the power to choose whether a member state can leave or not. That's how it is. So it is wrong to compare a region of a country seceding than comparing a country leaving the EU. Which is more similar to a country leaving NATO for example.

This one seems a bit random, but there's been pretty good reasons for Australia to be relevant in the global tech news in the last few years. Our government is burning down as many freedoms as they can get away with in the tech space, and setting a dangerous precedent for other western countries to follow. It can't hurt to have everyone reminded of that every now and then.

Also, I'd guess Melbourne and Sydney are probably trending upwards in both startups and VC available, which would result in more visitors here from these parts.
What I've never understood is why not just create an other ranking that competes with the Shanghai ranking. I wish polytechnique or some other institution of high learning published their own ranking and marketed it as well as that ranking was marketed.

You are right, it's pure bullshit and heavily favors big institutions rather than small ones which does mean that French style grande écoles are penalized but the solution isn't to conform to it but instead to change the way universities is ranked.

I have also been very disappointed with Macron's policies when it comes to education. The higher tuition for foreigners is also I believe a mistake since it is good for a country when highly educated foreigners come to study there. France is at a disadvantage when attracting foreign talents due to the language barrier but could compensate for it thanks to the low tuitions. Now with those changes, it will become harder and diminish the cultural influence that France had. Not a good long term move.

Do you eat meat at all? If so, how were the animals raised, slaughtered and processed?

This ban seems rather hypocritical to me given the atrocities happening in mass meat production.

While there are absolutely terrible things happening in Foie Gras production (I would never, ever buy any products from Hungary, as a for example) the really good stuff is raised quite humanely.[1]

To me this just looks like an attempt for quick political gain without any advantage to any factory raised animal (which, for the record, I regard as one of our biggest moral failings as humans).
