Kennedymars 2008

2008-09-21T11:47:00.003+02:00

President John F. Kennedy heeft ooit beweerd dat de moderne mens niet meer in staat zou zijn om 50 mijl in 20 uur te voet af te leggen. Uit die uitdaging is later de Kennedymars ontstaan en dat evenement wordt ook jaarlijks in Nederland gehouden.

Gisteren heb ik (ongetraind) die 80km Kennedymars gelopen, in 15 uur, voor de 2e keer. En wat mij betreft is dit ook de laatste keer, wat een afzien was het! Halverwege was ik het al zat, en wilde eigelijk opgeven maar tijdens de pauze ging het wel weer een beetje en besloot ik weer op pad te gaan. Door het mentaal aan elkaar knopen van de afstanden tussen de rustpunten heb ik het uiteindelijk gehaald, maar onderweg heb ik vaak ondervonden dat dit eigenlijk gekkenwerk is. De zoete smaak van de volharding maakt echter veel goed!

Een beschrijving van de route van de Twentse Kennedymars:

Als om 22.00 uur het startschot voor de 22e editie is gegeven gaan de wandelaars richting de Veldmaat. Bij het winkelcentrum zijn weer de nodige activiteiten met medewerking van een dweilorkest. En na circa 4,5 km komt men weer door het centrum van Haaksbergen waar ook volop gefeest wordt in de tent en bij het podium. Hier wordt dan gerekend op een grote schare publiek. Via het volkspark Scholtenhagen en een aantal rustige wegen komt men na bijna 10 km aan op de eerste verzorgingspost bij de eeuwenoude< watermolen, die fraai verlicht is en natuurlijk ook draait. Ook hier zal men d.m.v. muziek een gezellige sfeer scheppen.

Na deze verzorgingspost gaat de wandelmeute via de buurtschap de Honesch terug naar het centrum van Haaksbergen. In de evenementenhal 'de Bouwmeester' is de eerst rust- en verzorgingspost gevestigd. Men heeft hier 21,1 km afgelegd. De Halve Nachtwandelmarathon heeft hier haar wandeling volbracht en zal de beloning in ontvangst kunnen nemen of nog even gezellig feest vieren in de evenementenhal 'de Bouwmeester'.

De Kennedymars- en Nachtwandelmarathonlopers gaan vanaf hier op weg voor hun tweede lus. Men gaat via de Goorsestraat,Richterstraat, en het buurtschap Brammelo naar de Rietmolen. Bij café Kuppers heeft men dan 32,1 km afgelegd, hier is dan weer een rust en verzorgingspost ingericht.

Na de koffie gaat men weer richting Haaksbergen door het buurtschap Brammelo. Na ruim 6 km is een wagenrust bij de familie Kuiper (38,5 km). Hier kan men even uitblazen en bijtanken. Een disco zal hier de wandelaars wakker houden. Van hieruit is het bijna 4 km naar evenementenhal 'de Bouwmeester'. De lopers van Nachtmarathon hebben hier hun wandeling er op zitten en kunnen genieten van een biertje en de muziek. De Kennedymars lopers hebben er hier 42,2 opzitten

Ze beginnen aan de derde lus, die hen samen met de Dagwandelmarathon lopers (zij kunnen starten vanaf 06.00 tot 07.00 ) naar Boekelo zal brengen. Men verlaat via het Industrieterrein ‘Stepelo’ Haaksbergen en via het fraaie Stepelerveld komt men in Boekelo waar men kan genieten van een welverdiende rust. De afstand die men af moet leggen om deze post te bereiken is 9,6 km. De Kennedymars lopers hebben er hier 51,8 km opzitten.

Via het Altenabos gaat men weer naar Haaksbergen. Een leuke route door bos en over oude boerenerven. In de evenementenhal ‘de Bouwmeester' kunnen de lopers van de Kennedymars en Dagwandelmarathon even uitblazen. Men heeft er dan resp. 63,1 of 20,9 km opzitten.

De laatste vierde lus gaat richting Buurse. Het Buurserzand met de fraaie fiets- en wandelpaden zal doorkruist worden. Bij de werkschuur van Natuurmonumenten is een rust- en verzorgingsplaats ingericht. Op deze lus komen ook de deelnemers aan de Halve Dagwandelmarathon, zij starten vanaf 09.00 uur tot 10.00 uur. Bij de rust- en verzorgingspost hebben de deelnemers 72,8 km. De Dagwandelmarathon lopers hebben hier 34,6 km afgelegd en diegene die de halve marathon lopen hebben hier 13,7 km gelopen.

Na deze rust beginnen de lopers aan de laatste loodjes en gaan ook weer door het Buurserzand en komen op de laatste bekende verzorgingspost aan de Ronde Bultenweg. Bij deze post komen ook de deelnemers van de Mini Kennedymars (die vanaf 10.00 uur kunnen starten) aan. Gezamenlijk gaan alle lopers dan via de Esch naar het centrum van Haaksbergen met als doel uiteraard de finish in evenementenhal ‘de Bouwmeester’. Hier worden ze onthaald door familie, vrienden en bekenden. Natuurlijk is ook de presentator aanwezig en is er volop muziek.

De invloed van Internet op ons brein

2008-07-20T21:27:00.005+02:00

Nicholas Carr heeft een boeiend diepgaand artikel geschreven over de invloed van Internet op ons brein. In historisch perspectief geplaatst, laat hij zien dat ons vermogen om de aandacht langdurig te richten op een bepaald onderwerp, afneemt sinds de opkomst van het veelzijdige alom beschikbare informatienetwerk dat Internet heet. Het artikel zelf spreekt de inhoud ervan paradoxaal genoeg tegen, kijk zelf maar hier: http://www.theatlantic.com/doc/200807/google.

The Next Web en startups

2008-04-04T21:02:00.007+02:00

The Next Web Conference, vandaag en gisteren in Amsterdam gehouden, was prima te volgen via de live stream van NOS.nl. Mijn conclusie is dat er niet veel nieuws te horen en te zien is anders dan wat al via de diverse weblogs zoals TechCrunch en The Next Web zelf ~~natuurlijk~~.

© Pieter Baert

Ik miste vooral de visionaire en filosofische speeches. Men had bv Kevin Kelly kunnen uitnodigen. Aan de andere kant willen de jongens en meisjes van The Next Web het ook wel hip en flitsend houden, en dat is ze prima gelukt! De echt inhoudelijke informatie komt immers toch wel tot ons via feeds waarop we ons kunnen abonneren.

Als ik een startup ging opzetten, dan zou deze volgens mij alleen succesvol worden als:
- er gefocust wordt op 1 service (alleen de grote bedrijven doen meer)
- de service aan de volgende criteria voldoet:
- simpel te gebruiken
- relevant: voorzien in een specifieke behoefte
- uniek: like.no.other
- performant: goede architectuur en snelle infrastructuur

Omdat veel startups niet aan deze criteria voldoen, vind ik ze niet interessant genoeg. Maar het blijft altijd spanned om te zien welke wel levensvatbaar zijn.

Bringing the cloud with you

via Official Google Docs Blog by Andrew Chang on 3/31/08

Posted by: Philip Tucker, Software Engineer, Google Docs

We know that many of you have been waiting for offline access to Google Docs, and I'm happy to tell you we'll be rolling it out over the next few weeks, starting today with a small percentage of users.

Here's why I'm excited about this development. My migration from the desktop to 'the cloud' started with my Gmail account. I could access my mail from anywhere, search it all in one place, and never need to migrate to a new account. It was great. Then I started using Google Calendar to organize my schedule all in one place.

So now I find myself with this drive to make my desktop as sparse as possible, both in data and software. I want to move it all into the cloud. There are still times I use my desktop word processor, but I want to minimize context switching between apps. Cloud computing is great, but you need the cloud to make it work. On an airplane, on the shuttle commuting to work, or at home when my cable modem goes down, I want to work on my documents. And, until now, that usually meant saving a copy and editing on the desktop.

Now there's a better solution. With Google Docs offline (powered by Google Gears), I can take my little piece of the cloud with me wherever I go. Once enabled, I have a local version of my document list and editors, along with my documents.

As long as I have an Internet connection, every change I make is saved to the cloud. When I lose my connection, I sacrifice some features, but I can still access my documents (for this initial release, you can view and edit word processing documents; right now we don't support offline access to presentations or spreadsheets - see our help center for details). Everything I need is saved locally. And I do everything through my web browser, even when I'm offline (the goodness that Google Gears provides). When my connection comes back, my documents sync up again with the server.

It's all pretty seamless: I don't have to remember to save my documents locally before packing my laptop for a trip. I don't have to remember to save my changes as soon as I get back online. And I don't have to switch applications based on network connectivity. With the extra peace of mind, I can more fully rely on this tool for my important documents.

One more note: Offline access is only available in English. We're working on offline access in other languages. It will also be available to Google Apps users soon, and domain administrators that want it now can opt-in via their control panel.

Google's April Fools' Day Hoaxes Go International

Google's April Fools' Day Hoaxes Go International

via Google Operating System by Ionut Alex Chitu on 4/1/08

Google has a long history of April Fools' Day hoaxes, but this year there's something different: many Google offices from outside of US have created their own tricks.

Google Japan added a special Universal Search result for Dajare, "a kind of comic Japanese wordplay, similar in spirit to an English pun relying on similarities in the pronunciation of words to create a simple joke".

Google China's blog describes a social search engine that would replace Google's algorithms. "We sort of search results purely from a human decision, [without] machine's intervention."

Google Australia announces gDay, a new feature of Google that lets you search today the web pages published tomorrow. "Google spiders crawl publicly available web information and our index of historic, cached web content. Using a mashup of numerous factors such as recurrence plots, fuzzy measure analysis, online betting odds and the weather forecast from the iGoogle weather gadget, we can create a sophisticated model of what the internet will look like 24 hours from now. We can use this technique to predict almost anything on the web – tomorrow's share price movements, sports results or news events. Plus, using language regression analysis, Google can even predict the actual wording of blogs and newspaper columns, 24 hours before they're written!"

Google Korea found a new technology for translating dialects that was integrated in Gmail and Google Talk.

But Google's US teams didn't lose their humor.

Google's main blog announces Virgle. "Virgin founder Richard Branson and Google co-founders Larry Page and Sergey Brin will be leading hundreds of users on one of the grandest adventures in human history: Project Virgle, the first permanent human colony on Mars."

Google Docs has a new option: create a new airplane. For now, the only model available is the one below:

If Google Australia lets you see the future, Gmail gives you the option to change the past with Gmail Custom Time. "Just click Set custom time from the Compose view. Any email you send to the past appears in the proper chronological order in your recipient's inbox."

YouTube tries to rickroll everyone by linking all the featured videos from the homepage to Rick Astley's (in)famous song "Never Gonna Give You Up".

Google Book Search has a new feature: capturing a book's smell. "I'm pleased to let you know that we've made some headway with one type of volume we've struggled with in the past: books employing scratch-and-sniff technology. Using special equipment and tricky JavaScript, we're now able to capture some of the smells during the scanning process and then embed them in your web browser when you preview these titles in Google Book Search."

Google Calendar launches a wake up kit. "The wake up notification uses several progressively more annoying alerts to wake you up. First it will send an SMS message to your phone. If that fails, more coercive means will be used. The kit includes an industrial-sized bucket and is designed to be connected to your water main for automatic filling. In addition, a bed-flipping device is included for forceful removal from your sleeping quarters."

Google Talk goes green by launching a bot that translates conversations into the IM lingo. "In honor of Earth Day (3 weeks from today: April 22, 2008), on that day our Google Talk servers will start automatically sending your conversations using IM-speak instead of normal words. We know you'll all want to practice your IM-speak, so we're helping by introducing a new translation bot, en2im@bot.talk.google.com, which will translate your conversations into IM-speak, to help you get used to the new lingo." LOL!

orkut makes fun of its strange name and replaces it with "yogurt". In 2006, Loren Baker posted 10 reasons why Brazilians love orkut. Among them, "Orkut sounds like Yakult or iogurte (yogurt). Yakult is the Brazilian version of the popular Japanese Yakult yogurt drink. Everyone drinks it in Brazil when they're kids."

If I were to choose the best April Fools' Day 2008 hoax from Google, I'd go with Google Australia's gDay. I had a similar idea for this year: monitoring how web pages evolve and predicting how they look in the future, but I decided not to use it.

How Google keeps your information secure

via Official Google Blog by Karen on 3/10/08

Posted by Douglas Merrill, VP of Engineering

As many of you know, we spend a lot of time around here thinking about new products to help you run your life more efficiently, whether that’s organizing email in a better way, sharing pictures with friends, or collaborating in real time on documents. What you may not know is that we also spend a lot of time thinking about the security that goes into those products, and more specifically the ways we can protect you and your private information.

While the chances are that you'll never have a security problem, we take security very seriously, and that's why we have some of the best engineers in the world working here to secure information. Much of their work is confidential, but we do want to share some of the ways we're protecting your data. There are a few things you should know about how we handle confidential information:

Philosophy: First is our philosophy. At Google, security is a continuous process. We don't just "check" a product for security before we launch it -- we are thinking about security before the product is even created, and we are building it in throughout the product's development. Also critical is our belief in layered protection. It's much like securing your house. You put your most private information in a safe. You secure the safe in your house, which is protected with locks and possibly an alarm system. And then you have the neighborhood watch program or the local police monitoring your neighborhood. It's very similar at Google. Our most sensitive information is difficult to find or access (the safe). Our network and facilities (the house) are protected in both high- and low-tech ways: encryption, alarms, and other technology for our systems, and strong physical security at our facilities. And finally, we've learned that when security is done right, it's done best as a community (the neighborhood); we encourage everyone to help us identify potential problems and solutions. Researchers who work at security and technology companies all over the world are constantly looking for security problems on the Internet, and we work closely with that community to find and fix potential problems.

Technology: These layers of protection are built on the best security technology in the world. While we employ products developed by others in the security community, we build a lot of our security technology ourselves. Some of the most innovative components of our security architecture focus on automation and scale. These are important to us because we're handling searches, emails, and other activities for millions of users every day. To keep our security processes a step ahead, we automate the way we test our software for possible security vulnerabilities and the way we monitor for possible security attacks. We're also constantly seeking more ways to use encryption and other technical measures to protect your data, while still maintaining a great user experience.

Process: In addition to technology, we have a set of processes that dictate how we secure confidential information at Google and who can access it. We carefully manage access to confidential information of any sort, and very few Googlers have access to what we consider very sensitive data. This is in no small part because there's very little reason for us to provide that access -- most of our processes are automated, and don't require much human intervention. Of course, the limited number of people who are granted access to sensitive data must have special approval. And while we hold ourselves to a very high standard, we also work to ensure that our processes meet (and in many cases exceed) industry standards. These include audits for Sarbanes-Oxley, SAS 70, PCI (payment card industry) compliance, and more. By working with independent auditors, who evaluate compliance with standards that hold hundreds of different companies to very rigorous requirements, we add another layer of checks and balances to our security processes.

People: The most important part of our approach to security is our people. Google employs some of the best and brightest security engineers in the world. Many of our engineers came from very high-profile security environments, such as banks, credit card companies, and high-volume retail organizations, and a large number of them hold PhDs and patents in security and software engineering. As you can imagine, our engineers are smart and curious and are on the lookout for security anomalies and best practices in the industry. Our engineers have published hundreds of academic papers on technically detailed topics such as drive-by downloads that install malware (PDF file) or hostile virtualized environments. (You can find some of these papers here.) What's more, we cultivate a collaborative approach to security among all of our engineers, requiring everyone to pass a coding style review (which enables us to control the type of code used here and how it's used in order to prevent software problems) and ensuring that all code at Google is reviewed by multiple engineers so that it meets our software and security standards.

And throughout the company, we use our own products. That means we protect your information with the same security that we use to protect our own company emails and documents. And while we continue to innovate with our products, we'll also continue to innovate in the world of security. For more on our approach to security, visit our Security and Product Safety page.
