Comment Re:What can Berners-Lee do here, really? (Score 1) 126

I consider Mozilla Firefox being on a decline as a good thing. The Mozilla Firefox development is covered by political statements weighting in the wrong direction. Statements as "Because Internet Explorer does it in the same way" are made over Chrome/Webkit still working as expected. Just read this bugs in hindsight. And this is only what I remembered. Mozilla became a commercial non-profit, with an office in the center of Paris that really can't be imagined. Someone/thing is keeping that alive.

As example; lets assume that in some cases insufficient funds would be the root cause of criminal activities. The justice system wants to provide retribution for society, but also would need to prepare the inmate at some time to join that same society again. But without a job, means of living, a motivation, that is just not going to happen hence the prison system provides education, a tablet for e-learning can help with that, like books currently do.

In The Netherlands some evidence based online psychology companies have emerged in the last 5 years. One of them is a spin off of the University of Amsterdam. I can also imagine that psychology programs assists with anger management and all kind of other issues that at this moment aren't really considered due to the lack of funds and therefore manpower.

I am not suggesting that that all people can change, given their past. But if nobody cares about what happens at the first day of them exiting the venue, that sounds like a really poor policy, after spending an Europe average of 102 euro per day (The Netherlands 202 euro) per inmate. That tablet would account for at most one prison day, if any evidence concludes that it would change behavior in a positive way, it is already a proper investment.

I hope nobody gets it in their minds to make inmates peddle or watch ads to reimburse their privileged tablet. And I can think of many other tasks... Next to that, like pen and paper a tablet could be the same kind of tool. But what does really make the behavioral difference required when freedom is granted back?

Comment Re:4-Megapixel Lens? (Score 1) 31

A lens passes light, in some sense it is a filter. The filter passes through information. Typically a lens is qualified in either lines-per-inch of megapixel. How can you check this out yourself? Just make a photo of a subject far away and tell if you can make a distinction between one row of pixels and the adjacent row. Typically the light blends because your sensor is better than the lens. unless you have some very nice (read: $$$) prime lens.

But in another subject. Why is this really news? The Elphel Eyesis 4pi designs are online for 5 years.

4. It should work, and not annoy me to figure out why and how it is broken.

For any competent user that is able to use a debugger the ability to actually figure out what is broken, and save significant amount of time doing so, is something that doesn't work for closed source software. Close source embraces a philosophy that any outsider is not competent and the product is pure magic. The fact that no public bugtrackers exists for close source software magnifies the root cause.

So people like to put expensive DBs on expensive servers?

Anyway, I have no idea what that web site is trying to say. I can't find a single mention of Postgres anywhere. It's all MSSQL, Sybase, Oracle, DB2, and some databases I've never heard of. Does the benchmarking software only run on those databases or something?

Check out the why: The entire industry including some open source databases target this benchmark. Obviously you don't have to play ball, but others are doing.

Splitting a query into parallel chunks only helps when your database server is idle, you know.

Many applications do not have many clients at the same time, but require peak performance. An example is GIS applications, the more obvious is crunching data for visualisation.

It sounds to me that your needs are different than what the rest of us expect from a database. Data warehousing perhaps?

We are talking about software that can handle hundreds of gigabytes of data. But the parent suggest PostgreSQL as example for the diversity SQL Server has to offer. If some article on PostgreSQL is written and someone replies SQLite does all that... what will your reply be?

Comment Re:Postgresql (Score 1) 314

Most database products (even open source ones) compete very well against PostgreSQL because the support of parallel query execution has been supported for years. PostgreSQL has only recently added some features in the direction. And we are not talking about N clients to 1 server, but 1 server with 1 query where only 1 CPU is used in the PostgreSQL case, and others automatically spread the workload.

Some other tricks from SQLserver are obviously the integration services (Extract-Transform-Load) and Analysis Services. Again you could use open source third party product such as Talend et al. Now I am aware these kind of smart clients should be seen as tooling on top of a database itself. But as long as those tools work very closely with one database... it basically prevents you from using anything else unless you want to integrate your own solution.

PostgreSQL has such amount of features, that as data integration toolkit it is great. But for performance I would not use a vanilla instance... since even tuning and automatically indexing is not something that the database does for you. And BTW... for performance look in this list.
