My personal take on this is that high IQ quickly turns into a liability in childhood. Particularly when entering the school system.

I believe the words "bored to tears" summarize the experience quite well.

While the majority of pupils get a standardized curriculum designed to keep their interest at a steady pace, pupils with a high learning capacity get no such thing. If they try to learn faster, it doesn't fit with the governance and management model within which the teacher must operate. Therefore, most teachers are at a loss when faced with these statistical outliers.

Also, other pupils may experience emotions of inadequacy and unfairness when a fellow pupil just blasts through the material in minutes that would take them all week. This may lead to the high capacity pupil being a target of some unfortunate group dynamics.

Since schools have no governance model for this, the high learning capacity pupil's school experience is essentially unmanaged. At a loss, society almost invariably resorts to platitudes like "No need to feel sorry for them, because they are so fortunate to be smart. We must focus on the pupils that struggle."

A few years down the line, the pupil's inner motivation may be completely replaced by depression, self-blaming or worse. Then the platitudes take a turn for the worse with blaming the pupil's willingness to work: "In fact, high IQ can reduce grit, since clever pattern matchers use their cleverness to avoid working hard on the toy problems of childhood."

Fortunately, my own school days are long since gone. Without blaming any person in the system, I can say: "Good riddance!" to this whole pitiful affair of how society treated me as a child.

Instead, I can draw attention to this problem by saying clearly that these are children that never asked for these gifts in the first place. Let's as a society realize that what we are doing to them is absolutely wrong and woefully irresponsible.

Fortunately, at least one western country has political attention on this right now. I will work hard and with "grit" to make sure that my experience and observations can help in creating new policies. In particular I wish to address how to practically leverage the pupils' own drive to learn without incurring social/peer stigma or ridiculous costs.


This is a huge problem.

We are perfectly happy to identify athletic talent and enact systems so that the athletically talented are matched up with peers who share their gifts, but we mostly refuse to do this for intellectual talent.

I was fortunate enough to attend a program that handled this pretty well. Basically it was 120 kids from 11-18 who skipped high school and attended university together instead. It’s called the Early Entrance Program and it’s at Cal State Los Angeles:

The issue I face is that I am raising my children in Portland, Oregon, so this program will not be an option for them. Our personal approach is to home school instead. And I’ll probably investigate starting something like the Early Entrance Program at the state university in Portland here.


I'll chime in.

Most chemical processes happen faster with a higher temperature. Some drugs decay into harmful substances (e.g. Aspirin).

Other factors, such as humidity or UV, may play a part as well.

Rather than testing every permutation of storage conditions over time, manufacturers put a safety margin. Individual consumers aren't in a position to remember exactly how they treated any given container of pills. Even if the manufacturer knew how a given sequence of storage practices affected their drug, nobody would be the wiser.


Ah, I see, thanks.


These guys know what they are doing. The guide rope coming undone may lead to safety improvements for other divers. The divers found themselves in a quite difficult situation, and through skill, resourcefulness and chance managed to find a way for both to come home alive and well.

A child of such a parent surely learns a thing or two about how to manage risk. Since life cannot be lived without risk, I would argue that such knowledge may better the child's chances in life.

Therefore, I argue this may be a better father than one that shies away from "unnecessary" risk.


This appears construed. LIFO: The human rights do not include a right to _enter_ any country (except maybe one's own). You may also not leave a country if you are subject to lawful arrest.

Sending money home is a most human thing to do. Sending welfare money home may be seen as defrauding the common insurance policy of the host country. And what are the component parts of the suggested increase in GWP? Travel? Housing?

Also: What are the effects on the host country labour market?

The nation state serves as an organizational unit in promoting stability in and between nations. Its borders are an inherent limit to this concept.

At these borders, the nation state can enforce the necessary controls to compensate for different legislation on VAT, gun ownership rules, as well as to ensure foreign forces cannot simply perform a sneak attack by infiltration.

In short: Borders promote a structured mechanism for supporting peace in a world with plenty of incentives for people to kill, raid, rape and pillage.


Unless you are a master of corporate-fu: You're going to be so popular! :)


My life is too important to me to sacrifice my purpose for the sake of popularity.


Can anybody give me an example of any dbms that spans the OLTP/OLAP gap properly _on the same data_?

Potentially added constraints: -ACID for OLTP

-## TB+

-30-way analytical joins on complex criteria and multiple data sets with billions of entries

-fast iterations on data prep for analytics, so analysts can make, find and correct errors

-proper workload management (almost no "stupidly designed" queries)

-HA

-HPC

I'm asking because I can't see this without hw and sw being integrated to allow for it (appliance). Are there any cloud offerings that live up to this?

EDIT: Formatting got mangled on submit.


Oracle does pretty well running OLTP and analytics workloads concurrently against the same schema. While I don't generally recommend doing so, you can fire off massive scans or complex joins against a production system doing thousands of transactions per second and it handles it just fine.

In my view, one reason that we don't see huge demand for this combination is that the schema that makes sense for analytics is often different from that which makes sense for the online system.


Not that I'm aware of. It's tricky because the data storage format, query scan method, data distribution etc. requirements are different for OLTP/OLAP. However you can replicate the data to both OLTP and OLAP database and use both of them at the same time. That's people usually do. In fact, even if there is a database for this use-case, it should probably do the same process internally so that you don't need to do it in application level.


I'm one of the founders at MemSQL, which does what you describe.


Totally tangential, but I'm curious if you could elaborate a bit on how compiled queries [1] work in MemSQL? Am I correctly guessing that it completely ditches the traditional Volcano-style iterator model, in a manner similar to HyPer [2]?

[1] https://docs.memsql.com/v5.8/docs/code-generation

[2] http://www.vldb.org/pvldb/vol4/p539-neumann.pdf


Looks like a sound design based on a cursory inspection :)

Question(s): Do you offer any appliances? The reason why I am asking is for computationally intense workloads where the same data may be shuffled around multiple times between processors. Can one e.g. set up MemSQL with RDMA over Infiniband?


MemSQL engineer here.

No, we do not offer appliances. We are a software only solution. I do not know of any deployments where RDMA is being utilized today. I'm interested in your use case. If you're so inclined, join chat.memsql.com (my UN is eklhad) and we can converse a bit more rapidly.


Thank you guys for your answers :)

I am charting the landscape of distributed database systems (federated and homogenous). Node interconnectivity is just one of many potential bottlenecks.

With a sufficiently complex query, redistribution of data by hash must occur a number of times for linear scalability (based on my understanding). Ethernet based interconnectivity typically suffers from high CPU utilization and various QoS issues for this particular use case. This also seems to apply to Ethernet based fabric offerings, though I haven't kept up with that field for a couple of years.

If you guys are encountering performance issues connected to either RAM=>CPU loading or data redistribution between nodes, you may want to keep this in mind.

I may get in touch via chat at a later time as I'm slightly more than average interested in HPC database systems :) The more offerings, the better!


Check snappydata ?


Netezza but IBM bought it and killed it.


SAP HANA?


It's in-memory so you also need TBs of memory in order to be able to use it for analytical workloads.


Proper risk management is serious business. "Risk" "management" in smaller businesses may just be pretended. This illusion will cost some time, focus and money to keep up. I believe that's the market referred to.


A lot of things in small companies are pretended, which I think was grandparent's point.

HR, benefits, invoicing, inventory tracking, project tracking, etc etc

And the fact that there are business providing most of those testify to how good of an idea it is (and how crappy the existing MBA-Sales enterprise solutions are).


SQL is the best when it comes to reasoning about information as tables. If you want to reason about tables as graphs, SQL becomes impractical for many applications.

Performance characteristics of different RDBMSs varies by orders of magnitude dependent on workloads.

Keys are also a flexible concept. They can be formalized to ensure referential integrity (domain), or you can join on whatever you want.

Recursive queries can handle some reasoning on graphs, but they quickly become impractical.

Even so: The flexibility SQL offers when you want to change which data you think should be related is tremendous - on HPC database machines :)


Regarding favours: People that feel entitled to one's time can go think about their own attitude. The goodwill you mention is not good will at all. Whether the declining party's true reason is laziness is literally none of your business - unless you have one of a very few types of relationships.


Sounds like they spend a lot of money on questionable "marketing". Also, one never knows where the true profits are recorded in the days of ubiquitous tax avoidance.


I'm not certain that marketing plays that huge of a role. They make the only drug on the market to treat hemolytic uremic syndrome, every medical student has to learn about it. Must be some other costs, or hiding of true profit as you suggest.


Sunk costs on failed treatments, generally. I don't remember the stat well enough, but it's something like a double-digit quantity of candidates fail for each single one that receives FDA approval.

Here's hoping someone else can investigate and share the exact number. I'm at a stoplight.
