76,000 colonies. A colonie is about 4,000 individual bees.

320 colonies at 4,000 are roughly 1,280,000 honeybees.

In fact BOBs are 10 times more effective than honeybees. They pollinate at a time where honeybees are still asleep.

And 4,000 is considered a small colonie. They go up to 70,000 and more in the right season.

franzpeterfolz | 8 years ago | on: Germany considers free public transport in fight to banish air pollution

Numbers for 2015 are

82,17 TerraWattHours exported

37,12 TWH imported

91,8 TWH nuclear

187,4 TWH regenerativ energy

The main problem Germany is facing, is the storage of Energy on Sunny, Windy days. Storing this energy in car Batteries would be an extra bonus. Plus, regenerativ energy is going to increase further.

Yes, your absolutely right about the coal plants. And I am pretty sure they are going to be shut down. But the main problem is, nuclear waste will stay for millions of years, while CO2 in the atmosphere will probably vanish in centuries. Not nice but that's the decision to make.

franzpeterfolz | 8 years ago | on: Germany considers free public transport in fight to banish air pollution

Well, plans say the government is subsidizing Electric cars and Plugin-Hybrids with 4,000 Euro. Half payed by the government and the other half from car manufacturers.

They even want to expand these subsidies to small businesses and extend the amount to 8,000 Euros.

The problem indeed is that this would not help to banish air pollution, because the numbers are to low. The second thing is, that only wealthier people would benefit from these subsidies. You have to be able to afford a new car at first. And second you have to be able to afford an electric car. And even if you are the typical buy brand new cars guy, you typically drive these cars 6 to 10 years. So these subsidies might come in an unpleasent moment of your car-buying-cycle.

Free public transportation could reduce car traffic and everybody could benefit. Even poor people.

franzpeterfolz | 8 years ago | on: Cortana is really bad

Well, the Projected Delivery Date is 25th November 2017.

How do I know? Took the number and looked it up at ups.

I think, I'm not sure, but I think, if ups delivers on time. Cortana will give you a message, stating the package will arive tomorrow right on 24th of November. Just one day before.

Maybe John David Back will give us an update, when his package arrived.

BTW delivery times in the US are terrible compared to Germany. Next Day delivery is the state of art. Germany is also much smaller in comparison.

Laser printers need much power for heating. Would it be possible to switch to a ink printer? They should work fine on 10 to 20 Watts. They even have external Poweradapters like a Laptop.

It depends on the usagepattern. Not printing enough would dry up the ink. Printing to much could be to expensive or to slow.

But heating dust up with a laser to melt it down on paper seems to be very inefficient in terms of energyefficiency.

franzpeterfolz | 9 years ago | on: Germany to Give €1B Electric Car Subsidy

So the German Prices 1 KwH is about .28$ 1 gallon is 3.78 liter 1 liter gas about 1.52$ 1 gallon is now at 5.70$

What are the prices in the USA right now.

The electricity prices include about .20 Euro taxes and subsidies for windharvesting and solar etc.

franzpeterfolz | 9 years ago | on: Germany to Give €1B Electric Car Subsidy

Just take a look at normal cars.

E.g. Ford Focus Sedan is starting at 17.000$, 2.0 Liter Engine, 160 horsepower.

Now take a Ford Focus from Germany with a comparable Engine (1.5L EcoBoost with 150 horsepower) Starting price is at 26.500$.

Audi A3 in Germany is starting at about 26.800 Euro.

Cars in the United States are way cheaper than in Germany.

So 4.000 Euro is quite some money to get EVs and normal cars into the same pricerange.

franzpeterfolz | 9 years ago | on: Germany to Give €1B Electric Car Subsidy

It is a political isue. In Germany the average income is at about 30.000,- Euro.

So many people cannot aford any EV, even the cheapest. So they are excluded from any subsidies. But they pay their taxes. They work for the rich people, the company owners. They work for their profits, so that the rich are able to pay taxes or transfer the money to panama and avoid paying taxes.

The party SPD is a working class party for those people earning about 30.000,- and less.

And now consider to explain those people, that they pay taxes to subsidies the drives for the rich people. Driving Porsche 918 with Weisach-Update for example.

There is no way to do this without an upper limit.

franzpeterfolz | 10 years ago | on: Is France's AZERTY keyboard heading for the scrapheap?

It takes time. So I started with a typing program (ktouch) and lections for neo2.

There are 6 layers, but you have to consider that uppercase and lowercase is almost the same. The layers 5 and 6 are not in my usage pattern. Layer 4 is one of the easiest to learn, because it maps the right hand to the numpad and the left one to arrows like sdfe in computer games. a for pos1 and g for end. So there is some easy logic behind this.

At the end there is just layer 3. The organisation of the braces is that they appear in pairs and are arranged in a pattern.

So in Zurich they do a little bit more french as in germany. So I didn't had to use accents a lot. So I can't say a lot about it. èéâǎȩẽ. These characters are a little bit away from the optimal position. But they do not need a Compose Button. èéâ only needs two button strokes. ǎȩẽ needs the Shift button for the first stroke. But the accents are every time on the same position just on different layers. A little bit difficult to explain. Especially if you have not used accents before.

What I would suggest is to take neo2 as a basic layout, take the good parts and addapt it to the usage pattern of the french language.

franzpeterfolz | 10 years ago | on: Is France's AZERTY keyboard heading for the scrapheap?

Not french, but german.

I just recently switched to the neo2 keyboard layout.

The hardest thing is unlearning quertz (almost like querty)

http://www.neo-layout.org/

It is highly optimized for the home row on the german vocabulary. Support for Programming is also very good.

It has 6 different layers • Lowercase • Uppercase • Special Characters (Braces etc.) • Navigation and Numbers • Greek Alphabet (same layout as normal Characters, ιαεοσ) • Mathematical signs Σℕℝ∂

But I rarely use layer 5 and 6.

I think layer 3,4 and 6 could be a good fit for every keyboard layout.

franzpeterfolz | 10 years ago | on: The O-Ring Theory of DevOps

Let's assume the leadtimes in the pipeline differ dramatically. l_1 ... l_n-1 take just minutes and l_n takes some days.

Maybe its a huge simulation or learning of a neural network.

In this theory the leadtimes are getting normalized and multiplied.

But in this pipeline, the process n is overweighting all the other processes, so that the leadtimes of the other processes are almost irrelevant compared to the leadtime of process n.

a. Lets assume leadtime of process 1 is missed by 50%. So it takes an additional minute.

b. Compared to process n, missing leadtime by 50%, taking an additional week.

Expected Quality would be the same for a and b. But the overall leadtime will differ in one week.

franzpeterfolz | 10 years ago | on: API server and a static front end – the future?

Well, I just disabled JavaScript with ScriptSafe recently due to security and privacy concerns.

And there are many blank pages I get to see, because of this kind of Architecture and CDN's. Nowadays even blogs with mostly static content don't work. That's realy annoying.

If you depend on search engines, remember you get penalties for this kind of sites. You need to have some kind of prerendering to satisfy you ChiefSearchEngineOptimizer.

How do you support Bookmarking in a Single Page Application? I think this is an essential feature and not trivial to implement correct.

I tried Angular. It works. It looks nice and smooth, but I don't think it is a good solution. JS is nice as an enhancement, but I don't like it as a dependency to use the web.

===Addit Not so long ago we have had similar approaches to JS-SPA. They were called Java Applets and Flash. These Technologies are dead. Everything you do today with JS was 10 years ago possible with these technologies. The only constant in the web that's gonna stay is HTML.

JS is overused. There are so many things you're better off without JS, like Blogs, Hackernews or simply valueable content. There might be usecases for SPA, but a high percentage are better off without these cool and fency stuff.

Eliminating Serverside Rendering for scalability reasons as a first step is often followed by implementing prerendered content in script-Tags or via react on node. The only thing that gets scaled is complexity.

franzpeterfolz | 10 years ago | on: Why Don't Software Developers Use Static Analysis Tools to Find Bugs?

Well, I did it the other way around. When my co-workers drove me crazy. I just launched Findbugs on their Repo/Projects and filed some bugs in the Bugtracker. That is just a matter of 5 Minutes to get them down to the ground and show that they are not that kind of Rockstar-Devs they pretend to be.

But never reveal your secret tools!

Well, and if they get curious about your magical Bug-Finding-Skills, they are easy to convince to use these tools. Its a kind of marketing.

franzpeterfolz | 11 years ago | on: Build Static Websites

If caching is setup properly, you won't need any Database-Querys unless your Content changes.

A static site needs also to be served. HTML-files are on the Servers Harddrive. They have to be read and send to the client.

A clever Caching-Strategy might beat this aproach by reading the files once and Serving the content from memory. When I write "reading the files once", this also includes making a db-query, rendering a HTML-Site and caching the result in a Tool like memcache to serve it from there.

franzpeterfolz | 11 years ago | on: Ask HN: How to use small chunks of time productively

Don't start working on things you can't finish! Seriously. If tools are missing or requirements are not well defined or other people you depend on have not delivered now, than simply don't start.

This approach can reduce your work in progress tremendously. The benefit is, that it becomes easier to choose from your open tasks.

When everything you need for your work is ready, you can finish your tasks. Otherwise you start working and interrupt yourself because you have to wait for others.

Making assumptions on not not well defined requirements may lead you to work which will be discarded upon wrong assumptions.

And last but not least:

Work on things that matter.

Follow those things and I promise you that the disruptions will disapear.

franzpeterfolz | 12 years ago | on: Data protection: Angela Merkel proposes Europe network

Well, how does it look when Merkel is talking about the internet.

Germany has a project called DE-Mail. https://en.wikipedia.org/wiki/De-Mail

It's a kind of E-Mail service to improve Data-Protection and get legally binding electronic communication. So far so good.

But how is this done, and what are the impacts. At first E-Mail got a price tag. Second, there is no End-To-End-Encryption. Third, you're legally bound if they say this mail arrived, no matter if you even noticed or read. 4th there are public companies involved, able to read high sensitive data sent by DE-Mail, because there is no End-to-End communication. This companies are also able, but not allowed, to send legally binding mails in your name. How could you prove, you didn't sent?

This is the context, when German politicians talk about the internet. They have no clue.
