Vitess is pretty close to magic for a lot of use cases. The downside of its rebalancer is that the re-sharding process requires a full expansion of the shards that are being re-balanced, which is to say if you have two shards [-80] and [80-

They meet once a week for a full day to discuss the course material with a paid tutor. That gives a good time to have those discussions and ask questions. You are completely correct about how hard independent study can be, in the group our

I am part of this increase, and after a full year homeschooling we will not be sending our kids back to traditional school. What we noticed is that our kids weren't actually learning, they were being pushed through a program so they co

Thankfully you are not the only person to realize this and a multi-billion dollar industry sprung up to help independent retailers compete. A Shopify website has a customer experience similar to Amazon. The real issue is Amazon has so much

I believe thats exactly how we stop that, by choosing not to shop at Amazon. The government is ( theoretically ) an expression of the will of the people, if the will of the people is to exploit others for their own benefit, the government w

It's not the mega conglomerates they are putting out of business. It's the bike stores, the hobby shops, the clothing boutiques. In the US with the purchase of Whole Foods, they are also moving more into groceries and everything e

I am happy the parts company is ditching Amazon, but its so much more important for us consumers to ditch amazon. I have cut my amazon purchases down to only 16 total items this year so far ( down from ~50 in 2020 ) and I am now only orderi

Why only one bedroom apartments? You can't build a community that you think will stand for any amount of time and be this hostile to families.

If that specific bill was the only debt we were printing to subsidize car dependence it would be bad enough, however the majority of spending is done by municipalities which sits currently at 4T and its estimated we need to add 6T to that o

If you want more walkable cities you have to stop subsidizing the suburban sprawl that has been paid for with debt spending. The infrastructure that is falling apart around us is happening because its unsustainable, and if we just print 1T

I have a very simple rule that I adopted when I first became a manager, and it has served me well. I won't ever fire someone for performance unless I have explicitly said to them. `If you don't do the following things in the given

Yeah, if you are doing global replication you are much more likely to fall behind so you should have aggressive monitoring on the replica to remove it if replica lag gets to high, that will prevent the primary from retaining WAL files for t

by dkhenry 5y ago
That is good and should prevent against bringing down the primary. There is still the issue with being able to get that region back online once replication is severed, which isn't always possible even with co-located systems.

by dkhenry 5y ago
Of the many things that can go wrong, the one I would be most worried about would be replication lag causing the disk on the primary to fill with WAL logs bringing down the primary, or if you have limited the WAL logs, the replica not being

This is very true, its hard to tell if the company you are going to join is well run, or awful. Stories people tell about startup's don't help since it can normalize bad behavior and make it seem like that is the industry norm ( i

This is one of the areas where Postgres is so far behind MySQL is embarrassing. Zero downtime migrations in MySQL have been a common method for over 10 years. This solution is far from ideal due to the use of Triggers which can greatly incr

The biggest thing is Saxon is a physical book, and it comes along with all the worksheets and tests and problem sets that we can copy and have them work on multiple times if needed. Specifically things like math facts and computations requi

Everyone in the homeschooling group my family attends generally pays for material, and then supplements with things that are free(ish). For example math for us is Saxon (paid), and then we will sometimes use Kahn (free) if the kids need ext

As a parent who has all three children fully home schooled now I can confidently say it is just the better way to educate children. The article slightly alludes to this, but homeschooling today is not the kids sitting at home independently
