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.

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.

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.

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!

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?

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

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.

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.

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.

The real problem is that the concept of "hate speech" is nonsensical. It is a term created exactly to polarize debates and prevent rational discourse. Calmly explain that to any one that attempts to use the term - or ask them to clarify exactly what they mean. We must reject politically engineered attempts to ruin the public debate.

How are we to know which words you mean, and which words you don't mean?

I assume this is one-sided, but since Dr. Laskar didn't get to present his side of the case in court, I believe it's appropriate to link to it: http://joylaskarstory.com/chronology/

You are mentioning implementation-specific issues that may have more than one solution.

If one goes to the heavy contenders in this space, e.g. Teradata, you may expect: - DMA for data retrieval - A suitable and linearly scalable network layer with Remote DMA - Row, columnar and hybrid storage options - Utilization of CPU vector options - Etc

The analytical database has become a commodity. I really like Postgres, but I would still do a very careful analysis of my business needs if I were to choose a DBMS when there is such a strong range of commercial options available.

Hear, hear!

With quantitative analytics being used and abused by ever more businesses, the advantage will go to those that can apply qualitative checks to their assumptions - and scale it.

Well, the CBP should bloody well train their staff on the rules they're tasked with enforcing.

I agree with this. Furthermore, the bright youths of the nineties spent a lot of time putting hardware (and software) together. Now a lot of this is on a commodity level, open source packages abound, and the theory is more accessible than ever.

Software as the future is yesterday's news.

I believe the first thing to understand about SQL is that everything is a table (aka relation). Once one understands that, the idea of modelling entities as relations and relationships as references starts making sense. Also, the tenets of normalization become understandable on an intuitive level.

Sadly, many IT professionals lack the intuition on this.

SQL is a highly sophisticated language since many years. Having done insane amounts of data prepping and validation for analytics, I will attest to this.

However, if I am writing software in .NET, I would trade away SQL for LINQ any day of the week. (Preferrably by means of some sort of intuitive DAL.)

So, the specifics: - The guy takes his time to offer high quality advice - The guy offers a lot of high quality advice - No real specifics are given on _why_ he's a jerk - Higher throughput is taken as a proxy for better performance without accounting for quality, NFRs etc.

This piece - while interesting - doesn't give the information necessary for the reader to arrive at an independent conclusion.

I like the irony of Heisenberg leaving a legacy of uncertainty.

Hitler's policies in Poland and elsewhere from 1939 on may have swayed Heisenberg from contributing to the German war effort. Thankfully, there never was a nazi A-bomb - paired with their cruise and ballistic missiles, the tide of war could have turned again even fairly late in 1944.

lutusp is referring to this study in particular. There are many variables that potentially should be corrected for that aren't mentioned in the article.

Is that so strange?

Interesting definition. Do you have a source for it. It seems ambiguous.

From the Wikipedia article on relational databases, subsection relational model. "This model organizes data into one or more tables (or "relations") of columns and rows, with a unique key identifying each row. Rows are also called records or tuples."

"Relational" means "tabular". (A "relation" in relational theory is a table with a name, fields with names and types, and the data in the table.)

A "relationship" in an ER diagram maps to a "reference" in relational theory. This is part of the type safety/domain system of RDBMSs.

If these concepts are muddled, SQL will never quite make sense :)

That's why ASCII was designed with record and field separators. Unfortunately, it's not used (de facto) for delimited files.

Sounds like you needed better sales people.

Any US taxes due to their US H1-B operations can also be reduced to zero by inflated internal pricing / profit shifting to their Indian operations. Check the tax rates and median IT salaries in Indian service export cities.

Also, they try to rotate employees abroad between several countries so as to keep them on short term visa & tax rules - and maybe also to avoid them getting uppity or starting unions...

I understand. The projection you link to here is the one I keep in my living room.

About satire and/or parody: I would try to master the form first, as well as finding out where it's effective. 'Allo 'allo and Candide are in my opinion brilliant examples. In a rational discussion it easily appears a bit like mockery, or "did you stop beating your wife".

As for the comment you replied to: I find it very credible that these things aren't so important to everyday map users. The Mercator projection does have its advantages for some applications. Other projections for other applications. Putting a sphere on a rectangular piece of paper will involve tradeoffs.

The sheer utility of a suitable projection far outweighs any notions of trying to put any particular nation or continent - for most people.
