A lattice has a least upper bound and greatest lower bound. A semilattice only has one of these two.
A monotonic operation is one that’s either non-decreasing or non-increasing. That is, it never reverses direction.
So in the context of conflict-free replicated data types, you can think of something like an append-only database as a basic example. Over time, the database can only grow or stay the same. It can never shrink. This allows you to split the database into pieces and distribute them. You always know they can be merged back together because they’re append-only. This makes it a join semilattice with the union of corresponding tables being the least upper bound operation.
I'm currently working on my homework on one of my module (CS5250 Advanced Operating Systems) and I find this site very easy to understand compared to the slides + discussion by my professor. I'm not saying that my professor is not that good, its just that the way information are laid out on this site is very easy to follow.
Anyway, does anyone have any other sites that they can recommend? (not the Intel one. just knowing that it has 4.7k pages makes me not go near it)
I'm not sure how easy it is in Japan but in Singapore, It just took me 10-15 mins to file my tax.
1. Login to IRAS(tax bureau) portal using the national ID (for me as foreigner, I used my employment pass ID)
2. Open the page for filing income tax
3. I entered total annual salary and allowances
4. I have donated to a government-recognized charity and this is automatically reflected on the form. It seems that the charity uploads donation infos to IRAS
5. Check if the tax relief for having a child is there
6. Click submit
7. Review and re-submit
You also have an option to do installment, deducting from your bank account monthly.
I don't have any other source of income so it will be different for other people.
I've actually played SC1 over VNC while on a tablet, casually. With the exception of the noticeable click lag from the network, it was actually very enjoyable. I would definitely buy a version made for that form factor.
It's definitely not a feasible setup for playing against humans. You absolutely need a keyboard to play SC1/2 seriously. The use case, if I remember correctly, was the height of laziness-driven innovation for me: I wanted to play a bot match while lounging in a hammock and didn't a laptop at the time.
What really struck me, though, was how suited for a smallish tablet the original game is. If you dumb down the interface just a little it would be flawless. I've played around with a few mobile or tablet-based MOBAs trying to get my starcraft fix, but I can't find an equivalent in that or mobile RTS realm.
I'm more disappointed that there won't be an official Linux release. The 1998 version works fine with WINE so I can still hope that they don't break anything with the remake.
Since it won't even be using a 3D engine (let alone any modern APIs like DX 12) I would think that any tweaks needed for WINE to run it well should be pretty minor.
Using that same logic though, I would have thought that making a Linux release would have also been pretty trivial for Blizzard to do, but given their history I suspect they have a policy of avoiding this.
I used wine for a bit but feel its important to mention warzone 2100 its what seems to satisfy my starcraft urges. At one point i feel that it was more in depth. they have online servers ip play very detailed and still being updated muilti platform.
once I got my head around the game I am addicted to it.
https://wz2100.net/ They have many AI modes for the computer. Its very popular in the Linux world.
I had to mention it. I too would like there to be a Linux version available for the latest Starcraft. but until that happens I feel this is the best alternative.
note here is a tree of sorts that show what you need to build research to have said weapon or tech. with out this it was just a crazy world where you start playing the computer and all of sudden they have hover then planes and you are like how did they get to that.
This new system that uses events looks more flexible since it is decoupled on the application logic. I think the downside with this one is that the new system has a lot of moving parts. Also, changes in logic/new events must be communicated and should be supported before the main app is put into production.
In my previous team, we instead use the string "null" to represent NULL. Its pretty dumb but we haven't thought of any other way.
What I like about DynamoDB is that you can scale the table easily. You don't need a dedicated DBA to maintain your database.
For what I don't like
1. You pay for what IOPS you allocated
2. You can't share free IOPS to other tables
3. Getting a snapshot of the whole DB is impossible, DB backups are not transactional
4. Use EMR or DataPipeline for backups
5. If you reach your IOPS limit, you need to retry your writes/updates instead of delayed ack's. Others uses libraries that limits writes but its per server and doesn't account the free writes on other servers since the accounting is on the client level
