It’s not a win win policy. The citizens lose massive amount of their money to government on the bond yield delta. It preys on people not knowing the effect of long term compound interest.
Edit: in fact interest delta is how banks make their huge profits except the government here does it by force.
What's your source on the yield delta? In fact if you bought regular Singapore government t bills you will actually get a lower rate than the CPF rate. And neither do banks and saving plans give higher rates.
In this case the citizens are forced to save, but the interest they're given is less than what they would have earned by saving the same amount on their own.
Also, the average person in the United States does have meaningful investments toward retirement age.
This assumes citizens actually putp a lions share of their money into more risky investmemt vehicles. For reference, this may not be the case with a large swathes of our older population. Bank rates, t bills and bonds here are generally lower than cpf. If you are a high income earner the contribution is capped and combined with low taxes this is not a bad thing.
I was just setting up a new machine and was setting up the Rust environment. The very first thing rustup-init asked was to install Visual Studio before proceeding. It was like 20-30gb of stuff installed before moving forward.
This tool would be a great help if I knew beforehand.
Space offers some unique benefits that enable computing that’s impossible or very hard to do on earth. E.g. Super conducting computing is possible, which can be thousands times to millions times faster than current CPU while using very little energy. When the satellite moves in the shade of the earth, temperature drops significantly. It can be low enough to enable superconducting. When the satellite moves under the sun, the solar panel can start charging up the battery to power the ongoing operation.
i don't understand? you won't insulate the craft from the sun? and you expect the craft to get rid of its heat just from being behind the earth for a moment?
When did I say no insulation? If it took only one moment for the satellite to fly by behind the whole earth, its speed is so great that it would be flung out of the solar system.
Strings in textual index are already compressed, with common prefix compression or other schemes. They are perfectly queryable. Not sure if their compression scheme is for index or data columns.
Global column dictionary has more complexity than normal. Now you are touching more pages than just the index pages and data page. The dictionary entries are sorted, so you need to worry about page expansion and contraction. They sidestep the problems by making it immutable, presumably building it up front by scanning all the data.
Not sure why using FSST is better than using a standard compression algorithm to compress the dictionary entries.
Storing the strings themselves as dictionary IDs is a good idea, as they can be processed quickly with SIMD.
> Not sure why using FSST is better than using a standard compression algorithm to compress the dictionary entries.
I believe the reason is that FSST allows access to individual strings in the compressed corpus, which is required for fast random access. This is more important for OLTP than OLAP, I assume.
More standard compression algorithms, such as zstd, might decompress very fast, but I don't think they allow that
Nice to have a huge speed up. Kudos for applying the right tools and right approaches to get it done. I especially like your explanation of how to utilize SIMD in Zig. Learned something today.
Nope. The Windows NT kernel is fantastic. It's the Windows user mode apps that people complain about. Replacing the Windows NT kernel with the Linux kernel while keeping the user mode crust serves no purpose.
There's the plug-in solar panel system. It's very easy to install. It's suitable for renters to add supplemental solar power with little cost and effort. It's portable enough that renters can bring them to their next rentals.
It's very popular in Germany, with several million units installed. They call it balcony solar panel. People hang the panels on their balconies in apartment buildings. Germany allows up to 800-watt systems.
It's a very simple system, a solar panel coupled with a micro inverter that converts DC to AC power. It is plugged into a regular wall outlet to provide additional power to the home. The added power is an additional source of electricity in addition to the grid. Any electrical devices drawing power from the circuit draw from the closet source first (due to Kirchhoff's Law), i.e. from the solar panel, then any additional need will be drawn from the farther away grid.
The micro inverter needs to be UL 16741 compliant for anti-islanding protection, to shut off in case the grid has shut power down, so that the solar panel won't back feed power into the grid.
In U.S., Utah has already passed a law to allow plug-in solar systems for up to 1200 watts without permit requirement and allowing back-feed into the grid. A few other states are considering.
There are limits to the power fed into a circuit. Normal household electrical wire can handle up to 15amp (1800 watts on 120V) of electric load. The plug-in power from the solar panels should not exceed the limit. This means the power generated is meant to supplement the household power need rather than completely covering it. Any reduction from the grid helps.
I talked to my city's (in California) building department. They haven't heard of it and need time to do research. The building inspector says that as long as the solar panels are not modifying the structure of the building (on roof or on wall), they don't care. They said putting the panels on the ground in the yard is fine.
That's swell if you have a balcony facing the sun and enough space for 4m2 of solar without blocking your neighbors' sun. In my unit for example, it's completely infeasible.
At the moment I’m building a succinct data structure library, doing one algorithm at a time. There have been some very impressive papers came out recently. The numbers look promising.
I used to have an unexplained resistance to buy Bose products. After the hinge of my Sony mx-1000 headphones broke in to two places, I gave in and got a Bose qc. Man, the build quality was insanely good. The sound was really good. And it’s really comfortable to wear. I had changed my view.
This is going to read like I'm shilling but: I was so impressed with Bose QC headphones that i stocked up and gave out 7 pairs to my closest friends and family this year for christmas
Thee noise cancellation was unmatched several years ago. I picked up mine because we were spending hours in the data center. Suddenly we could work and take calls in that hell. I still have those, but the AirPods have taken their place on flights. It’s just less to bring with me.
