What's with the "This being Europe" being repeated over and over?


Well...it's Europe. As a member of the Euro, Spain has vastly less control over their monetary policy than any truly sovereign state on the face of the planet. Conversely, as a member of the EU, they also have vastly less support from a central government than any province or state would have. They also face an incredibly sclerotic bureaucracy and a non-functional political process, dominated by groups and factions which (to put it mildly) do not have their best interests at heart.

To a first approximation, there is nowhere else on Earth where this debt crisis would be simultaneously so serious and so hard to deal with. You can't treat this like you were dealing with the US, or China, South-East Asia. This is Europe and that means that, barring a miracle, we're all[1] probably screwed.

[1]: Well, anyone who relies on the global economy for income, goods, or services, anyhow. Which would be, uh, all of us on HN, at a minimum...


As a Swiss I have to say: I hope you're wrong. Unfortunately, all indicators say you're right.


I fail to see why setting the transaction isolation level to read uncommitted would make any difference to the data load process.


Without thinking about it to hard my guess is there is some overhead in tracking what is readable and what is not readable at the higher read levels. Read uncommitted means it doesn't have to track anything.


Writes still take locks. The isolation level is called Read-uncommitted for a reason.


From October 29, 2010.


True.

It seems that this was from a presentation at StrangeLoop 2011 (never heard of it before) that occured from 18 to 20 of September (https://thestrangeloop.com/news/11/01/27/strange-loop-2011) -- it ended yesterday!

Recordings will be available (http://groups.google.com/group/cascalog-user/msg/d357e51cbbb...), I just hope I remember to come back and check for them.

There are some other slide decks available from the conference (http://lanyrd.com/2011/strange-loop/coverage/); some other presentations seem interesting.

There is also another awesome slide deck (this time with annotations) from another presentation from Bill Odom, regarding key mappings: http://billodom.com/talks/vim-key-mapping.pdf


You can press the tab key in Vim to get command auto completion.

For example, :colo<tab> completes to :colorscheme.


If hibernation didn't use compression, there was no need for CPU involvement due to DMA. Since there would be no CPU involvement, being multi-core enabled wouldn't be of help.

...and I don't think mentioning the source makes it right.


There is no need to save the home location with the time.

If you save the UTC date of the event, the localized date for some timezone can be extrapolated from it.


UTC is enough if we have a single instance of an event. If we have a concept of recurring event ("this event will occur on every Monday 9am"), then it's not enough.

I just wanted to highlight that "time" is a human concept that in informal setting means a lot of things, but when you start to model it formally, it can be more complex than a single timestamp.


That doesn't seem more helpful to me... it's just making the worst case worser.

In a situation which other queries would benefit from the id1, id2 order, and it wouldn't pay off creating another index, using a index seek instead a table scan is way better.


Making the worst case worser is the point. My assumption here was that the issue was catching this type of optimization problem during development, in which case using row values would help. The idea isn't that a table scan is better than an index scan, but that an index scan that isn't very selective will progressively get worse in terms of performance as the table grows, and possibly not be caught during development. Row values are the developer's way of saying "I want this condition to match an index on all columns, or not match at all".


- Charge frequently and don't allow full discharges (Li-ion batteries don't have memory);

- Keep batteries at temperatures lower than 30ºC;

- Charge with voltages lower than 4.1V/cell.


That's basically what it says, yeah. It's cool that you can just skim the three graphs and take away the main points of the article.

But that's hardly news.. The problem is that achieving these guidelines on a burning MacBook without an option to remove the cell is impossible :-/

Good thing the engineers know this all along and try to design so that the conditions are met to some extent.


I would just add to this, don't keep battery at 100% (unplug it when it's done charging)


> I would just add to this, don't keep battery at 100% (unplug it when it's done charging)

Absolutely incorrect. What makes you think that keeping a 100% charged battery plugged in bad? The device has its own charging circuitry that stops charging when full.


Anedoctal evidence, my SOs Dell's battery is basically dead(about 2-3minutes of charge) even though it has spent 95% of time plugged in fully charged.

Laptop forums are full of stories like this.


I would have thought the charging circuitry takes care of this?
