No, using transactions won't change anything here. > do not use throwaway placeholder rows to imitate a single item The point of using multiple rows for one product is to distribute the locks.

On a large scale "rare" events happen every day. That is why people use locks and transactions or other measures. In case with shopify, they want to decide whether the user may place order or not, at the moment when the user click

I now thought that "updating a row" might be more expensive than simply deleting because UPDATE is implemented as "mark row deleted" + "insert new version of a row" in a table which support multiple versions of

The fsync policy equivalent to SQL database would be "fsync on each change before reporting successful update to the app". Redis (as many NoSQL databases) also doesn't have SQL and is a pain to view the data, you need to writ

I mentioned that Redis can write changelog (called AOF in the docs [1]). However, if you tell it to do fsync on every update (like SQL databases do), it stops being that fast and spends time waiting for the filesystem. Furthermore, the RDB

The item is reserved when the user decides to place an order, but before paying for it. Not when a product is added to the cart because the user can keep it there for a month and end up not buying. You reserve the product by creating an &qu

Redis doesn't have transactions and persistence. No persistence means the data gets lost if machine shuts down or process crashes. Furthermore, after restart you will need to regenerate the data which can take time. That's why Red

The problem is that in this case you have to do splits/merges. And while there are products that are sold by 100 units at a time, I think in most cases people by 1-2 items so the hassle might be not worth it. Also you might not underst

Could not they shard the inventory table by shop_id? As I understand, the order includes only items from one store, so there is no need to keep all the stores in a single table. Also, I wonder why they could not have a row status (available

This shows that large companies making closed-source CPUs cannot be trusted. No doubt they would add whatever the government asks them to add. What can be done to mitigate this? One option would be to buy a large FPGA and flash it with an o

The article is too long. Judging about beauty standards by using sex dolls as an example is not very smart, first, because they are targeted to a small niche audience with specific tastes, second, they do not look especially attractive in t

Unless they are very tall or very short, probably no.

by codedokode 1mo ago
So for example, a 6 feet tall nerdy-looking geek is better than 5' 6" athlete or celebrity? Doesn't seem logical to me.

Weight varies much more than height (there is 3x-4x ratio between extreme values) and is instantly noticeable unlike height, so I think this is a bad comparison.

by codedokode 1mo ago
I am curious why is height important? Understandably, income affects the lifestyle and opportunities, but what does height affect? What changes if you are several inch taller or shorter? I cannot understand. Also, why those who care about h

IMEI is like a MAC address. You are identified by the data in the SIM card and not by IMEI.

by codedokode 1mo ago
IMEI allows tracking the phone if the user changes SIM card, so it is harmful. It is also available to any application to identify the phone. That is why it should be randomly changed. As for recovering stolen phones, nobody does this. Also

In C/C++ just adding two integers can lead to undefined behaviour. Your expectations are too high.

Is "defer" a good pattern? Aren't constructors/destructor pairs, like in C++/Rust, or "with" blocks in Python, better, because you cannot forget to call the destructor. I the first code example in the arti

This is why you should use open-source firmware where there is no registration and customer IDs. Also, the software should allow overwrite IMEI to a random value daily. > Boardman believed the meeting would finally address both issues. &

Probably parental control do not bring any profit (they actually add responsibilities, like restriction on ads, collection of data) so the large companies sabotage them by making them too complicated or broken?

There is nothing wrong if a teenager wants to know more about taxes. Although exposure to tax rates might cause a slight emotional trauma.
