Radar météo et les partys d'été

Petit truc pour les sorties à l'extérieur et une météo incertaine : les données de radar météo peuvent vous permettre de savoir si les orages et averses annoncés vous concernent ou non ! Utile pour savoir si on compte prendre le vélo, si on amène son parapluie, si on mange à l'intérieur ou l'extérieur, etc.

Naissances et pleine lune : c'est un mythe

Lors d'une conversation entre amis, le fameux mythe des naissances plus nombreuses lors des pleines lunes est revenu sur la table. Mais est-ce bien un mythe ou est-ce actuellement vrai ? Après quelques lectures sur Internet, je me suis retrouvé sur Wikipedia qui offre une bonne quantité de références scientifiques et les conclusions de l'analyse de l'ensemble des études scientifiques réalisés à ce sujet sont très claires : il n'y aucune corrélation entre le nombre de naissances et le cycle de la lune.

Tiré de l'article wikipedia:

Psychologist Ivan Kelly of the University of Saskatchewan (with James Rotton and Roger Culver) did a meta-analysis of thirty-seven studies that examined relationships between the moon's four phases and human behavior. The meta-analysis revealed no correlation. They also checked twenty-three studies that had claimed to show correlation, and nearly half of these contained at least one statistical error.[4] Kelly, Ronnie Martins, and Donald Saklofske evaluated twenty-one studies of births related to the phase of the moon and found no correlation. The scientific data "supports the view that there is no causal relationship between lunar phenomena and human behavior".[4] (Diefendorf 2007:113)
[...]
In 1959 Walter and Abraham Menaker reported that a study of over 510,000 births in New York City showed a 1 percent increase in births in the two weeks after full moon. In 1967 Walter Menaker studied another 500,000 births in New York City, and this time he found a 1 percent increase in births in the two-week period centered on the full moon. In 1973 M. Osley, D. Summerville, and L. B. Borst studied another 500,000 births in New York City, and they reported a 1 percent increase in birthsbefore the full moon. In 1957 Rippmann analyzed 9,551 births in Danville, PA and found no correlation between the birth rate and the phase of the moon [5]

Seréna - La contraception écologique

J'ai participé récemment à la formation offert par l'organisme Seréna et désir partager mon enthousiasme face à l'approche.


Qu'est-ce que c'est ?

C'est une méthode "sympto-thermique" de gestion naturelle de la fertilité féminine. Cette approche versatile peut être utilisée comme méthode de contraception naturelle ou, au contraire, pour augmenter les chances de conception. Le principe de la méthode sympto-thermique est d'utiliser plusieurs signes complémentaires (e.g. glaire cervicale, température du corps, col de l'utérus) pour venir identifier avec précision les périodes d'infertilité relative, de fertilité probable et d'infertilité certaine au cours d'un cycle menstruel. Dans l'ensemble, cette approche se veut "efficace, écologique, économique, fondée sur la coopération du couple et appuyée scientifiquement".

Pourquoi l'utiliser ?

Notamment pour se connaître soi-même - la sexualité est un des éléments centraux de la vie de couple. Mais aussi parce que c'est une forme de contraception écologique, qui peut être combinée à une autre (e.g. condom) durant la période de fertilité probable. Écologique car n'implique pas de produits chimiques (e.g. pilules ou condoms). Il y a d'autres raisons bien sûr. Par exemple, certaines femmes supportent mal la pilule, et d'autres utilisent la méthode afin de mieux identifier le meilleur moment pour obtenir une grossesse. Ça peut également nous faire découvrir des choses sur nous-mêmes dont nous n'avions pas conscience.

C'est certain que ça demande d'investir quelques minutes à tous les matins ; pour la prise de température et mettre les informations complémentaires dans un registre - ce 'prix à payer' m'apparait valoir la peine. Évidemment, je pourrai mieux vous dire ce que j'en pense après quelques mois/années d'utilisation de la méthode !

Ecosia or The Myth of Eco-friendly Search Engines

I've been invited to use Ecosia, a website you can use for web searches, will serve you ads and then give a share of the ad-revenu to the World Wildlife Fund. Ecosia claim you can save the environment if you use this tool. Let me share with you my serious doubts.

There's controversy regarding those tools. Some have been found in the past to be blatant frauds and some charge a significant amount of "administration fees", thus keeping for themselves a significant part of the ad-revenu to themselves.


I won't be using Ecosia myself, and here's why.

  1. I'm blocking ads using adblockplus.org and AdBlocker, so I would not provide any money to Ecosia/WWF anyway.
  2. I don't want or need a proxy to my web search, that actually means more data transfer on the 'net, and thus is by itself less ecological to use Ecosia than to access the search engine directly. In addition to more data transfer, the whole process will also eat up my personal time, waiting for Ecosia, a much smaller and slower server than Bing or Yahoo, to send me the search results along with content I don't need.
  3. I'm not sure Ecosia are trustable, especially when considering they're a for-profit organization.
  4. Ecosia uses Bing and Yahoo search engines, which arguably provide less interesting results than the Google engine. With Bing, I might end up needing to do more searches, loading more pages, thus making Ecosia less environmental-friendly than a accessing Google directly.
On the basis of those arguments, I claim using Ecosia is much worse for the environment than not using it.

In this critic of Ecosia, we learn "Kroll is just twenty-six years old, but this isn't his first attempt to get an eco-conscious site off the ground." and the conclusion: "Whether or not Ecosia is the greenest search engine on the web can't be verified, just as its claim of saving two meters per click on sponsored results can't be verified either. What is true, however, is that teaming up with WWF to raise funds for such a vital issue is important and respectable, so let's leave it at that."

In other words, I hate to be negative, but I think Ecosia is not part of the solution, I think it's an unnecessary proxy using resources (servers, bandwidth, time and human resources) that could be better used to the real benefit of the environment. As I mentioned, since I already block ads and plan to continue to do so, it doesn't make sense to use Ecosia since they won't make money out of me anyway.

What do you think?

PASS did not pass

What matters is trying I guess. The PASS project I submitted to Google's Project 10^100 did not make it. Somehow not surprising considering there was over 150,000 submissions.

That said, I was surprised of the selection made by googlers. The 16 top ideas aren't that interesting to my eyes. So be it! I just hope Google will use the pertinent ideas submitted in a useful way. They can surprise us - they already proved they're able to contribute positively to society in various ways.

Getting Things Done App Reviews: OmniFocus, Things, Life Balance, ThinkingRock and Chandler

Ok, I spent several hours over the last few weeks trying to seriously pinpoint the best Getting Things Done (GTD) app for my needs. The following is not a thorough review but might be useful to you, keep in mind your needs and tastes obviously differ from mines. Also take into account the timing: by the time you read this, it's probable these apps have been updated and may offer significant improvements. I tried five apps: Things, Life Balance, Chandler, ThinkingRock and OmniFocus. All the reviewed apps can run on MacOS X. I wish I could tell you I found the one app that fully fill all my needs, but it's not case.

First, why a GTD app? So many things I try or hope to accomplish in a diversity of overlapping contexts, I believe an app will help me keep track, thus not forget, the numerous next steps required to actually complete projects. A GTD app is also a mean to review ongoing and future projects and help me get the big picture of my life, personal and professional. Another expectation and intended goal is to reduce stress and frustrations.

At the moment, I use a combination of calendar events and reminders, a few flat to-do lists and inbox emails for organizing myself. To be honest, it works relatively well, but there's a lot of room for improvements. I feel I'm now ready for the next level: a dedicated GTD tool. Maybe I'll find out in the process that it doesn't help me that much after all, but I'm ready to try.

You'll find a lot of similar GTD app reviews on the Internet. It's worth reading many of them. It has been useful to me in order to identify the apps deserving review and providing clues about their general strengths and weaknesses. GTD apps require more than 10 minutes of exploration to get a good feeling of it and its ability to fulfill your needs and fit your task organization style. Screenshots and screencasts are never as revealing as actually trying the app for a few days.


Things



I evaluated version 1.1.3 of Things.

Good:
* The user interface is great looking and mostly efficient. That really matters.
* It's really easy to use. Easy learning curve.
* Things relies on tags, which are very flexible but require some appropriate organization (example).

Bad:
* Version 1.0 of Things was release at the beginning of the year, and as much as it's great looking, in terms of features, it shows.
* There is no way to export anything from Things to html or other sharable document. This is problematic to me since I work on Debian Linux and don't have access to MacOS X at work. This might be Things' showstopper to me - you see, I really want/need to be able to share the status of my work related tasks with my supervisors and colleagues. Highly probable that this is a feature that will "soon" be added to Things, but I'm not sure I wanna wait an unknown period of time. You can print groups of tasks to pdf, but that's a fairly limited workaround.
* Search is poor to the point of being almost broken. You can't use the search to find next actions related to two tags or more. This is a real inconvenience. Selecting tags in the top bar is the workaround.
* "Saved searches": you can't save a search (e.g. a user selection of tags) and add it to your left column. Since Things relies on tags, it would make sense to have automatically updated searches in your vertical bar.
* Missing: a web client to access and manage the Things database.
* No specific reviewing capabilities or easy why to set up automated focus criteria.

iPhone Things :
It's the iPhone/iPod Touch app that I could actually try, thanks to a colleague. Since there are no contexts in Things, you need to browse your next actions by "projects" and then filter by context tags: not the most efficient.

Final take on Things:
I'd like to choose Things, just because of its UI and tags approach. But you can't export to anything yet, making it impossible to share with colleagues at work, and you must systematicaly reselect the multiple tags to browse by context and projects or anything else (all represented by tags), which is a serious shortcoming in terms of efficiency. Sure, the developers will add these features eventually, but I don't think it's wise to go down that road not knowing when and if these missing features will make it. There is a Things forum, but it's strangely "hidden" in the sense that there is no link to it from most of the Things web pages. I'll keep an eye on Things' progress.


OmniFocus



I evaluated version 1.6.1 of OmniFocus.

Good:
* In general, offers many more features than all its competitors. This can quickly become important for many in the long run.
* The review mode. It's the only other reviewed GTD app (exception made of ThinkingRock) that specifically offers review mode capabilities. You can set next actions to be reviewed at a specific frequency, such as every week, every month or every year. Being able to review tasks every week without being distracted by long term projects that should be reviewed once every 6 months or so seems important to me.
* Tasks can be set as parallel or sequential, helping you focus on tasks you can accomplish now that don't require another task being completed first.
* Their "support Ninjas" are helpful and friendly.

Bad:
* Average user interface. Not bad, but average means there's obvious room for improvement.
* Contexts are exclusive. Despite the use of "perspectives" (which -must- be used for an efficient use of OmniFocus) to circumvent this limitation, this is annoying.
* Their implementation of "Contacts" is limiting. People are considered as contexts, and since next actions in OmniFocus can't have multiple contexts, that forces you to use perspectives, this too can be annoying.
* Missing: a web client to access and manage the OmniFocus database on the web. Hopefully, you can export subsets of your tasks to a beautiful enough html.

Final take on OmniFocus:
OmniFocus feels like a tool that has everything for me to start using it efficiently now. It meets my most of my requirements (such as exporting capabilities that provide a significant advantage over Things). It offers the most complete feature set of all GTD apps that I reviewed. OmniFocus is the tool I selected and will start using extensively.

Reading the comments in the forums informed me about what's coming in version 2, such as user-generated custom tags, so it should become even better later on but I prefer betting on a system and features I can use right away.


Life Balance



I quickly evaluated version 5.1 of Life Balance.

Good:
* I seriously considered Life Balance because it offers somethings the other GTD apps do not provide: a mean to help you spend more time on the things that really matter to you, not only a long list of tracked tasks. It prioritizes tasks to fit your goals, something you have to figure out without any help if you use Things or OmniFocus.
* Places, used as "contexts", are adequately designed: places can encompass multiple types of places, which is very convenient.

Bad:
* Nice colors, but overall, relatively poor user interface. Examples: (1) you can't move the events on the calendar by dragging them! (2) Entering a new task requires a lot of clicking on different tabs, moving sliders, etc., (3) search results are shown sequentially, no way to see all the results at once, etc. This is not efficient.
* No html export capabilities.
* No specific reviewing capabilities.

Final take on Life Balance:
Overall, Life Balance looks interesting, but the user interface annoys me. This, added to the fact that it does less than the other apps, has remove it of the realm of possibilities.


Chandler



I evaluated version 1.0.3 of Chandler, an open source GTD app.

Good:
* Open source, meaning free as in freedom. I can install it on as many computers as I want without having to wonder about licensing.
* Multiplatform. I will be able to used it at work (Debian Linux) as well as at home (MacOS X). This is a major plus to me and a real advantage over the other reviewed GTD apps.
* Web based too, meaning I can access it from work even if I don't/can't install the Desktop app. Thw web-based version is surprisingly usable, but miss a lot of features.
* Can send emails directly from the Chandler interface.
* Chandler web can be accessed from an iPhone provided you're connected to the Internet. There's also a free iPhone app, but it seems it only allows task entry, no task browsing.

Bad:
* It's a first version and it shows. Lots of missing features.
* No projects grouping or hierarchy, no contexts, only "Collections". This makes the browsing of tasks pretty difficult with only basic sorting capabilities, no filters. This can be a showstopper to many potential users, including me.
* Average user interface. No auto-completion, must drag and drop tasks to associate them with collections. No great MacOSX integration, such as with Mail and AddressBook.
* Limited set of features in regards to tasks: no way to set a start or due date, only a single date for the calendar display and alerts.
* No specific reviewing capabilities.

My final take on Chandler:
The great thing about Chandler being open source, you can easily try it for a long period of time to find out if it suit your needs or not. If you have some coding skills, you can even help by adding the features that you really need. However, at the moment, Chandler definitely looks like the least mature of these GTD apps - try it yourself!


ThinkingRock



I also took a look at another open source GTD app, namely ThinkingRock, version 2.2.1.

Good:
* It's also multiplatform but doesn't have a web-based client.
* It's pretty loyal to the GTD methodology.
* You can log and filter next actions adequately.

Bad:
* I personally don't like much the user interface (it's Java and far from being Mac-like) and the integration with other Mac apps such as iCal or Mail is poor to inexistent.
* I admit also not liking the fact that despite being fully open source, some modules are pay-for and syncing requires a yearly membership that can quickly end up more expensive than other apps.
* There is no iPhone app (one in the works).

Final take on ThinkingRock:
Overall, the ugly interface (that's subjective) and lack of a mean to sync between work and home makes me favor Chandler as an open source GTD app. Otherwise, ThinkingRock looks pretty solid (really) and may fit your needs, take a look at it.


Concluding remarks



Ok, I took a look at more than Things, OmniFocus, Life Balance, Chandler and ThinkRock, but they were the main competitors to me. For instance, I also took a look at the donationware iGTD2, which looks promising for a free app, but its development seems rather very slow (works with tags but awkward UI and no export capabilities at the moment, which seals the deal for me). You may also want to take a look at this recent comparison of GTD software.

What's was missing to help me decide is the ability to try the iPhone/iPod Touch apps for those software. It matters because I expect I'm going to frequently deal with my "GTD database system" directly on such a mobile device.

As you read above, I'm going the Omnifocus way, but I'll be keeping an eye to Chandler and Things. Things mostly out of curiosity, and Chandler because if it really gets improved over time, I could directly use it at work on Debian Linux (OmniFocus very likely staying a Mac-only app).

But I did not discussed the price? That's right. Whether it's free or 100$ is not a big enough difference to change anything. I want the best GTD for me and I'm ready to pay for it. Too bad I ended up selecting the most expensive of them, OmniFocus being 80$ (+ 20$ for the iPhone app), but it's not that a huge investment if you consider the importance that such an app can have on your life (big picture, reducing stress, not forgetting anything, etc). As an open source enthusiast, the fact that Chandler and ThinkingRock are open source gives them a real plus to me - they're just not mature enough yet.

Hope this was useful to you. Good luck finding the best Getting Things Done app for your needs!
