chestnut-tree··on Interview with Mitchell Baker - Mozilla Executive Chairwoman (Audio)
There is also a video version of this interview for UK viewers (not sure if it will work for viewers outside the UK)

chestnut-tree··on Why Meteor
The linked site won't display anything with Javascript disabled. Yet, when Javascript is enabled, we don't get a "web app", all we get is a page of text that could easily be coded in HTML and CSS. Presumably, building this site in meteor makes things easier for the developer. Does it make things easy for all users of the site? Look at the source code of the page after it's loaded.

What would a screen reader user hear? Is this site accessible? Does anyone really care?

Do sites like this point to a future where more and more web sites (not web apps) are built with Javascript frameworks? Is this a good thing? And can these sites acommodate all users? (Assuming they want to.)

chestnut-tree··on The web, it's for everyone
I understand the necessity of Javascript if you have a web app, but a lot of sites fail to display a page of text or a list of links if Javascript is disabled [1]. In my view, this is poor practice. What seems to be happening is that more and more people are using Javascript frameworks to build web sites (not web apps). This probably makes things easier for the developer. I'm not convinced it always makes for a better experience for users.

chestnut-tree··on Jaquard Loom
There's a short (3 min) video of how a Jacquard Loom works on the V&A website (V&A = Victoria & Albert Museum, London). There's no sound in the video but it shows, using animation, how patterns are woven into the fabric.

chestnut-tree··on Price of football (soccer) calculator 2014. How much will you spend?
An honest (but depressing) follow-up article by a former footballer on the cost of attending football matches:

"I understand after reading the BBC's Price of Football survey why there is concern over the rising cost of watching football in this country but, for most Premier League players, it is not something they are ever going to worry about.

To be completely honest, during my 20-year playing career, I never once thought about how much it was costing fans to go to games.

Other players might have been different, but I did not meet any."

chestnut-tree··on Reasons to use Bing
"improvements I'm looking for most revolve around respecting my privacy"

Bing's privacy policy is far from perfect, but it's more informative than Google's privacy policy. Here's an example extract from Bing's privacy policy

"We store search terms (and the cookie IDs associated with search terms) separately from any account information that directly identifies the user, such as name, email address and phone numbers. We have technological safeguards in place designed to prevent the unauthorised correlation of this data and we remove the entirety of the IP address after 6 months, and cookies and other cross session identifiers, after 18 months."

They also clearly tell you that wiping your search history doesn't mean erasing it from their search logs:

"For Bing Search in your browser, using the search terms you enter and the results you click, search history provides an easy way to revisit the sites and searches you've used before. You may clear your search history from appearing on the site by following the steps provided here or by going to the Bing preferences page noted above. Clearing your history removes it from the Search History service and prevents that history from being displayed on the site, but does not delete information from our standard search logs..."

http://www.microsoft.com/privacystatement/en-gb/bingandmsn/d...

Now compare that to Google's privacy policy which tells you nothing about whether your data is anonymised and for how long your data is kept. And all this from a company that does associate your search activity with your account (the one with with your date of birth, gender, location and possibly phone number). Remember too that Google arguably tracks and records online behaviour more than anyone else. Given the staggering amounts of data they collect, you'd think that would give them the impetus to be more informative about how they use your data, but it's quite the opposite. Their privacy policy tells you very little:

chestnut-tree··on Google Classroom
"...if you say "we don't track activities of school students", what does that mean?"

It means whatever Google explains it to mean. Google can either be vague about it, or they can be clear and informative. Google is the one collecting the data. Only they know what is captured and for what purpose. It's their responsibility to explain clearly what they track and record. All of the questions you pose are ones that Google can answer.

I disagree that strict wording prevents the evolution of the software. It might prevent Google from mining user data in order to build a profile of user likes and behaviour. But I consider this type of data capture and analysis to be extend beyond the boundaries of simply improving a piece of software.

chestnut-tree··on Google Classroom
"Schools don't buy software based on privacy"

They should do in my opinion. I find it depressing that so many people overlook or dismiss privacy concerns, particularly where kids are concerned.

The kids who are asked to use Google classroom have no choice in the matter since the decision is made by the school. That means they must sign up for a Google Account regardless of whether they want one. It's the responsibility of the adults to evaluate the impact of the software they choose. And privacy should be one of the top concerns for anyone evaluating software for educational use in my view.

Google's educational privacy policy [1] is carefully worded to state that they do not mine the content you upload to Google classroom ("Your data is yours"). What they don't state is whether they track the activities of school students and what this actually entails. How is that data aggregated? Who sees that data inside Google? Is the data anonymised? Or is it tied to an individual student?

Given that you must enter a date of birth to create a Google Account, Google is capturing very specific and personal details of thousands, perhaps millions of students. Over time, Google will have amassed a staggering amount of information about the behaviour and activities of these students and will continue to do so into their adult lives (if the students continue to use their Google Account).

If Google isn't tracking the online activities of Google classroom users, why do they not simply state that?

chestnut-tree··on The Urbanization of the Eastern Gray Squirrel in the United States (2013)
On a slight tangent...grey squirrels are considered an invasive species in the UK. They were not originally native to the UK, but after their introduction from North America they quickly outstripped the native red squirrels in population numbers. They are heavier than red squirrels and outcompete them for food. They also carry a virus which is harmful to red squirrels but harmless to themselves.

Grey squirrels are absent from most of mainland Europe (red squirrels are the native species). However, there is a small population of grey squirrels in Italy. The concern is that these grey squirrels may spread into other continental countries and affect the native red squirrel populations.

Earlier this year, Imperial College London revealed details of a study into the genetic diversity of Italian grey squirrel populations:

"Genotyping of grey squirrels sampled from Italy and the UK shows a direct link between genetic diversity and their ability to invade new environments."

chestnut-tree··on Will the Ebola virus go airborne?
I mentioned this in a previous discussion on Ebola, but thought it might be worth repeating. Last week, the BBC broadcast a generally informative documentary about Ebola. The programme talks to survivors of the virus, to the staff of Médecins Sans Frontières (MSF) treating victims, to Peter Piot, the Belgian doctor who discovered the virus (and established that the disease was not airborne) and the medical staff seeking a cure. There are some harrowing scenes.

For UK viewers, it's available on iPlayer until Friday 19 Sept. 2014 http://www.bbc.co.uk/iplayer/episode/b04hcthj/

For everyone else, someone's uploaded it to YouTube, although the last 10 minutes are missing https://www.youtube.com/watch?v=bjuQofIleOg

chestnut-tree··on The Mathematics of Ebola Trigger Stark Warnings
If you're in the UK, there's an informative BBC documentary on Ebola broadcast just last week. The programme talks to survivors of the virus, to the staff of Médecins Sans Frontières (MSF) treating victims, to Peter Piot, the Belgian doctor who discovered the virus (and established that the disease was not airborne) and the medical staff seeking a cure. There are some harrowing scenes.

chestnut-tree··on Snowden Documents Indicate NSA Has Breached Deutsche Telekom
The BBC broadcast a good documentary on the broad issue of internet survelliance a few weeks ago (Horizon: Inside the Dark Web). It's been uploaded to YouTube and is well worth a watch.

http://www.youtube.com/watch?v=fTjNkbLBEqg

There is a segment in the programme that starts at 4 mins 50 sec that explains how key fibre optic cables that connect the UK and US handle as much as 25% of all internet traffic. It also explains how relatively simple it is for GCHQ to insert an "optical tap" that allows them to capture the data that flows through the cables.

chestnut-tree··on On the Scottish independence referendum and the post-Westphalian settlement
"In fact the SNP is rather keen on encouraging immigration. I'd far rather have the right to live and work anywhere in the EU than be trapped in the UK with Boris Johnson as PM running second hand UKIP policies."

The SNP proposed plan is to encourage skilled workers (from outside the EU) using a controlled points-based system. That's quite a different policy position to the EU where EU citizens can freely live and work in any EU country. I doubt many people in the UK would object to the skilled immigration policy the SNP proposes. But, of course, we need workers of all skill levels. I agree that the rhetoric from the UKIP and Conservative party on this subject (and the toxic British Press) is often alarmist and inflammatory.

chestnut-tree··on The defenders of anonymity on the internet
For those in the UK, the accompanying Horizon episode is now online.

http://www.bbc.co.uk/iplayer/episode/b04grp09/

The 60 minute running time meant the programme had to skim the surface for some topics. Nevertheless, I thought the programme was well-made and informative. Recommended.

chestnut-tree··on What I use instead of Google services
"It pains me to hear intelligent people talk about being "tracked" as something "bad" a priori."

Tracking is bad when you know little to nothing about what is being is tracked about you and how that information is used. While you might get targeted or personalised results as a result of tracking, that is likely just a small outcome of the data collected about you. Who knows what else is being analysed or number-crunched about your online behaviour? If you read Google's privacy policy, the most notable aspect is how little it tells you. Nothing about how your data is aggregated, who sees your data, how long that data is kept for, whether it's anonymised. Is the data collected to "protect Google and our users" (their words) used solely for that purpose? (For example, providing your date-of-birth for age verification and your mobile number for two-factor authentication.) Or is this information also used for tracking and profile-building? These are all reasonable questions to ask any company that tracks you online or asks for your personal information. But Google aren't giving answers. And Google arguably tracks online behaviour more than anyone else.

chestnut-tree··on Show HN: Scottish Independence Referendum Heatmap
This is a nice idea. My UX suggestions:

- display the heatmap first - have a prominent link saying something like: add your vote to the map. When someone clicks that link, ask them to enter their location (city or town and country), then ask them the same question the Scots will vote for in the referendum: Should Scotland be an independent country? Yes/No.

I think the auto-detect location causes too many problems and may have privacy implications if, as another poster says, you can identify quite precise locations.

What would be really nice would be a map similar to the Book Depository ("Watch people shop" map):

http://www.bookdepository.com/live

In this case, you would display a pop-up each time someone voted with the name of their town or city and whether they'd voted Yes or No.

chestnut-tree··on City of Munich Considers Switching Back From Linux to Windows (In German)
"Linux will succeed as a desktop environment only when (and if) its various factions agree on a single model and a single goal."

Many Linux users probably don't want to see a single model. They like the choice of being able to choose from different distributions and their own desktop model.

Ubuntu is probably the closest to being a consistent desktop environment and look how much grief they get from some Linux users over their UX choices. The open source model works for software, but it can't work for UX or design (at least I'm not convinced it can) because you can't design by commitee - any yet everyone wants a say in the UX.

Would it have been better for Munich to have specified open document or data formats rather than the choice of software? This is what the UK government has recently done [1]. The choice of software is up to the individual departments as long as the software can read or create the open formats etc. At least this gives you the choice of switching to dfferent software without being tied to a single vendor's closed-sorce document format.

chestnut-tree··on Choose Firefox Now, Or Later You Won't Get A Choice
I don't view Google as either evil or benevolent. I view them as a corporation that acts in its own self-interest (as you'd expect). They do a lot of good things for the tech community such as releasing open source code. However, I often avoid their products because they are not open about what they track and record. That doesn't matter to many people, including many people in the tech community, but it matters to me.

Google arguably tracks online activity more than any other company. They propbably know more about your online behaviour than you do yourself. They have made tracking appear to be a perfectly reasonable and normal thing to do. They even have an OS (ChromeOS) that tracks everything you do from the apps you use to the web pages you visit, to even the documents you print (all routed through Google's cloud print service, even if your printer is sitting next to your ChromeBook). This isn't even done anonymously given that you have to sign in to use these services (you can't use a ChromeBook without signing in, using it as a guest limits what you can do). How many people would be happy to sign in to MacOS, Windows, Linux and know that everything they were doing was being recorded and tracked? Meanwhile, the tech community just gives Google the easiest ride possible on such matters.

I don't believe Google does anything remotely sinister with the data it collects. But it is a staggering amount of data that they capture. And if you read their lengthy privacy policy, it's notable how little it tells you. How is my data aggregated? Who sees it inside Google? How is it anonymised (if indeed it is - no mention of this in their privacy policy). Some of Google's services ask for very personal info: date of birth, mobile phone number. It's reasonable to want to know what Google uses this data for. Is is really just for security and verification? If they cared about privacy, they'd actually tell you. Their statements about privacy are always framed in terms of security. Yes, privacy is not possible without security, but security does not equal privacy. To me Google's attitude is summed up thus: we'll do everything to keep yoru data secure but we won't stop tracking you to death.

chestnut-tree··on Death by Inches: The battle over the metric system in America
Interesting...I'm in the UK, for me 24°C with a light breeze makes for a perfect Summer's day: warm enough to walk around without sweating buckets. 30°C is uncomfortably hot. I guess it's all relative to what you're used to (and what you're doing e.g. day at the beach or walking in the city).
chestnut-tree··on “Theater” vs. “Theatre”: The Great New York Times Language Swap
Another difference in usage between British English and American English: In the US, you go to a movie theater to see a film. Or you go to the theater to see a play.

In the UK, you go to a cinema to see a film. Going to the theatre is understood to mean going to see a play/musical/performing arts.

chestnut-tree··on U.K. National Grid status
Also interesting to note is that the UK and Germany top a list of the EU’s most polluting coal-fired power stations. These were the findings from a recent report by environmental campaigners. The report called "Europe’s dirty 30" looks at CO2 emissions from coal power plants in the EU.

From the report:

"Germany and the UK are the self-declared climate champions of the EU. However, Germany uses more coal to generate electricity than any other EU country, while the UK comes third in absolute coal consumption for power after Poland;"

Here's the 10 most co2-polluting thermal power plants in the EU according to the report

  1. Bełchatów, Poland
  2. Neurath, Germany
  3. Niederaussem, Germany
  4. Jänschwalde, Germany
  5. Boxberg, Germany
  6. Drax, United Kingdom
  7. Weisweiler, Germany
  8. Agios Dimitrios, Greece
  9. Brindisi Sud, Italy
  10. Lippendorf, Germany
The full ranking of 30 power plants is in the following report (3.1 mb) http://awsassets.panda.org/downloads/dirty_30_report_finale....

chestnut-tree··on A Traditional City Primer
I think this is a rather romanticised view of a traditional city. I don't want to live in a city dominated by cars, but that doesn't mean the best alternative is to build extremely narrow streets.

All cities need contrasting spaces. Even the medieval town or city was marked by narrow streets that led to an open piazza or square. The feeling of walking from a confined narrow space into a wide open expanse can give a feeling of exhiliration. It's something architects continue to use today inside buildings. Think of the walk through a corridor into the grounds of a stadium and the excitement it generates. Or the excitement of walking through a corridor in a theatre before you enter the large expanse of the auditorium.

The scale and proportion of buildngs in relation to one another creates a sense of enclosure that can either feel comfortable or uncomfortable. The author calls the extremely narrow streets "intimate" and they are in many cases, but they can also be claustrophobic (especially if you live in them).

For housing, not everyone will want to live in streets as narrow as the pictures in the blog post. Who doesn't prefer long views out of their window? (Preferably of some greenery) That doesn't mean building huge spaces between houses as is often the case in modern car suburbs. But there needs to be enough distance to psychologically feel you have a sense of privacy from your neighbours.

Here is a random Victorian street (in a very expensive part of London) that I think has a good scale. The road is not too wide. Cars are parked on the street rather than in garages. The houses are of fairly high density. This is a better template for housing than modern car susburbs in my view. But it won't be for everyone.

chestnut-tree··on Firefox 31.0
It says the following from a post on the Chromium blog from January 2012

"After two weeks, any associated information, such as your IP address, is stripped, and only the URL itself is retained." ( From: http://blog.chromium.org/2012/01/all-about-safe-browsing.htm... )

As a Firefox user, I really think it's poor form on the part of Mozilla to not provide any additional information or re-assurances on their website about the data captured and recorded by Google. Mozilla's slogan on their homepage is "Commited to your privacy and an open web". Being committed to privacy means being open and explicit about the data captured through their browser services, no matter how innocuous the data might seem. It also means presenting that information clearly and making it easy to find. People can then make informed choices about whether they want to use such services.

This is the sort of thing I would have expected them to have said:

"When you download a file from a web page, Firefox checks that the file does not contain a virus or malware before you save it. To check the file is safe to download, Firefox contacts Google to use a service they provide called Safe Browsing. Google checks if the file is harmful or safe, and sends this information back to Firefox (this normally happens in a few seconds). If the file is safe, Firefox will start the download. If the file is harmful, Firefox will block the download and display a warning message.

When Firefox uses the Safe Browsing feature, it needs to send Google information about your download. Google records the following information from Firefox: your IP address, the name of the file you are downloading, the address of the website, and [insert any other data recorded here]. [Also insert a re-assurance that Google does not keep a record of all your downloads against your Google account or against your IP address - assuming this is the case. Also explain how Google uses that info. and how long it's kept for etc.]

[Then finally explain how to switch off this feature if you don't want to use Google's Safe Browsing feature.]"

chestnut-tree··on Ask HN: Is Your Income above Your Country's Median Income?
This interactive infographic from the BBC gives you a global overview of average wages in different countries. You can type in your monthly salary to see how near or far you are to the average wage in your country.

It obviously comes with lots of caveats and tells you nothing about the quality of life in a particular country. It's still quite eye-opening though.

chestnut-tree··on Laser-based projection technology will make cinema screens bigger and brighter
"OK, raise your hand if the reason you don't go to movies is because the screens aren't big and bright enough."

I'm probably in the minority, but I actually don't go to the cinema if I know the film is being shown in a small auditorium. It doesn't matter what the type of film is, I want to see it on a medium or large screen. I hate walking into an auditorium only to find a tiny screen - it ruins the whole experience for me. You also pay the same ticket price as the cinemagoers watching a different film in a much larger auditorium (with bigger screen).

I realise that cinemas can't fill their larger auditoriums with certain films, but some of the smaller auditoriums I've sat in have screens not much bigger than what a home projector will give you. Unfortunately, a lot of indpendent cinemas have some of the smallest screens I've seen. I'd rather wait for the DVD than pay for a paltry screen experience.

So yes, for me at least, a bigger screen, and a brighter picture does influence whether or not I would go to the cinema.

chestnut-tree··on Why I don’t eat on Mondays
There is some evidence that intermittent fasting can help you lose weight and improve your health. In fact, there have been a plethora of books on the subject. In the UK, this type of fasting diet became very popular after the BBC broadcast a (not very good) documentary about it in 2012. The presenter of the programme (Michael Mosley) then went on to write a best-selling book on the subject.

If you're in the UK, you can still watch the programme on iPlayer

chestnut-tree··on Events that sparked WWI
The BBC is broadcasting and publishing tons of stuff about WWI. Perhaps too much to be honest. However, for those who are interested in the history, they have some informative guides.

chestnut-tree··on Material world: how Google discovered what software is made of
"What does any of that even mean?"

The new guidelines are much better than what they had before. The new visual design is also much better. However, some of the language used to describe the new design sounds inflated and a bit pretentious (it's ripe for parody!)

They've gone for a clear and uncluttered visual look. Hopefully, the next iteration of their guidelines will also include simple, clear and unpretentious copy.

An example of a really well-written design patterns guide is from the gov.uk site. It's not an equivalent of the Google design guide, but in terms of how to write guidelines and recommendations, it's the best example I've seen
