I had the same thing happen with one of my photos of lightning in London. I actually thought my shot had been ripped off at first glance, then realised it was from a different angle.

Alternative, from the Telegraph: https://www.telegraph.co.uk/news/picturegalleries/earth/2515...


Looks at first sight like much of a bigger coincidence, but given that you probably both used a long shutter speed (yours seems to have been 6s) and selected the nicest of a number of shots, it's not like there are crazy chances against getting two almost identical shots like this.


Oh yeah, I don't deny it isn't insanely improbable. Still, finding same strike in a newspaper, shot from a very similar angle, was quite surprising.


Nice quadruple-negative.


Surprisingly readable!


Actually that could be much more likely if both used automated triggering.


Yep, this is one situation where it's actually reasonable. The fact that they both used automatic triggering, and that took a lot of pictures over the period of the thunderstorm make it realistic. I personally don't believe the man in the article. It's easy to make a second account to pretend to be a different photographer (or have a friend pretend), and equally easy to set up 2 cameras to a trigger. There's a lot of competition in photography now days, so I would not be surprised to discover yet another publicity stunt.


The bolt of lightning is clearly identical, but I'm having a difficult time correlating buildings between the two shots. My guess is they were taken a mile or two apart.


IIRC the other shot is somewhere south of the river. I worked it out at the time. I was near Tower Bridge on the north side.


fwiw, yours is nicer :)


I found this post about latency of input devices very interesting: https://danluu.com/keyboard-latency/


Love this sort of thing.

Porting an ancient 6502 Forth to Z80. Nobody will ever use it and there are already loads of Z80 Forths around, but it's fun and forces me to learn exactly how a language that's always interested me works. Not on Github yet.


Agreed, and it's become common on many more cars than supercars to add valves to make exhausts noisier. I suspect these valves are not triggered in regulatory exhaust noise tests.

From Jaguar's website:

  Every F‑TYPE is fitted with an Active Sports Exhaust 
  that creates a race‑car inspired crescendo. 
  The exhaust system reacts to throttle position, speed 
  and engine revs by opening active valves. When open, 
  these valves allow exhaust gases to take a more direct,
  less restrictive route through the rear silencer
  producing a much richer, more exhilarating sound. Where
  fitted, the Switchable Active Exhaust, allows you to
  manually open the exhaust valves so you can enjoy
  F‑TYPE’s stirring soundtrack at all engine speeds. This 
  feature is optional on F‑TYPE and standard on all other 
  models.


basically, above a certain price point cars are designed for stupid wankers


There are plenty of high perf/luxury cars which are very quiet. I think there are customers at every price point who want ridiculously loud exhausts.


> above a certain price point

Maybe lower than you think... several Ford products over the last few years have done things like run sound tubes to the cabin or use the radio to simulate engine noise. I think it's kind of silly myself, but whatever.

> cars are designed for stupid wankers

Or at least people with different interests. Just because you think your own interests make sense doesn't mean other people have to agree or share the same interests that you do.


So, it turns out there are people who enjoy different things than you do. No need to insult them because of that.


The whole intentionally loud thing is a bit different than just differing tastes, as it is inflicted upon unrelated bystanders.


A few years ago some Ford cars had been found to amplify their engine noise through the speakers. At least they kept it to the driver.


lots of cars have this today


There's a similar story about the Audi S4 V8's exhaust note. The engineers wanted it to be louder than they thought their management would approve. So, what they did is demo a version that was louder than what they wanted, and when management complained they reduced it to what they wanted to begin with.

So essentially a muffler bypass valve? You can buy aftermarket valves like this from Summit Racing and JEGS - they aren't expensive, they come in a variety of styles (full manual where you have to unbolt them underneath the car, manual-actuated by a cable, electric actuated by a motor, and one company makes a "stealth" version).

Legality of use on public roads varies...


We use ZFS (on Linux) clones to instantly fork a read-only replica of our production database, to create r/w copies. We also currently have these upgraded in-place to 9.6 (we're still on 9.5) for testing.

Docker-compose and a makefile make it all very straightforward.


This is cool. Always worth spending some time setting up psql.

In my psqlrc I also have a bunch of "macros" (unfortunately no parameters in psql) for common stuff like transaction handling and SET ROLE / RESET ROLE, lock monitoring etc.: https://github.com/hollobon/psqlrc/blob/master/psqlrc.conf Some of it only works on <=9.4.


I did too, but I thought it was going to be a mail client (https://en.m.wikipedia.org/wiki/Elm_(email_client))


> The average beer is stronger than it was 20 years ago

I very much doubt this. High strength lagers are much less popular than they were 20 years ago, not least because of beer tax that scales with strength. http://www.telegraph.co.uk/news/health/news/11455150/Britain...


This is probably very, very regional.

IPA's have grown in popularity, for what it's worth, and are generally higher alcohol (5-6% in UK, 7-10% in the US).


The biggest selling cask ale in the UK (Greene King IPA), is 3.6% abv


We used this in production at my previous role and it was fantastic. There are a few rough edges but it became markedly more reliable over the 2 years or so we used it. It handled huge (well over 100KB) queries generated by SQLAlchemy with ease and was lightening fast.

We were using it as part of a custom BI tool for portfolio risk analysis. The data was mastered in postgresql and loaded into MonetDB for OLAP stuff.

The developers are pretty responsive to questions and bug reports.


Do you know if it's possible to expose an MDX or similar interface to MonetDB for a BI purpose?

I see many references to being able to define your own language, so I wonder if this has been done. I don't see anything explicit when looking through the site.

I ask because many popular visualization and reporting tools can natively generate MDX queries.


It can be done through Mondrian OLAP. See mondrian-rest [0] for an example implementation.

Cool! Thanks.

I had heard of Mondrian, but didn't think to check from that end if it could use MonetDB as a back end.


SQLAlchemy dialect maintainer here. I'm happy to hear somebody is using it, I've been working on it for a while but in the last 2 years I only received one bug report. And I don't think that is because the code is flawless.
