CmdrTaco has left the building (Slashdot)

c
30 seconds after saving the last Slashdot story

Slashdot, with CmdrTaco (Rob Malda), had a big influence in shaping early online media, since 1997. E.g Slashdot effect. CmdrTaco has now given up his posting rights to the site completely. Reason?

After 14 years and over 15,000 stories posted, it’s finally time for me to say Good-Bye to Slashdot. The internet has changed dramatically since I started here, and that’s part of my reason for leaving. For me, the Slashdot of today is fused to the Slashdot of the past. This makes it really hard to objectively consider the future of the site. Posting stories has always been my favorite part of the job. I created Slashdot to share these stories with my friends from IRC and school. It was never ‘work’. I wish I could continue to post stories forever, but those closest to me know that if I maintained the ability to post, I’d never move on. I’ll continue to read Slashdot and hopefully my occasional story submissions will make the cut.

Knowning when to stop is just as important as being successful in the first place. Respect and all luck in your other adventures CmdrTaco! Wonder, was he an apple fanboy?

          Nasa’s Direction 2011

          shuttle

          Today, or this weekend, the last space shuttle flight will commence.There is much emotional goodbyes going around. However, there are plenty of reasons to stop. For example the space shuttle was too expensive, ineffective. Its advantage as large space cargo delivery fully undercut by the 1/4 of a price conventional rockets. Now, by ending the Shuttle Program, Nasa says it can use all that money to fund research for better space flight and reaching its goals faster. But will this happen? Critics still say No.

          Nasa plans in their eyes don’t provide enough focus to make their success likely. The proposed “Flexible plans” seem increasingly fewer plans.
          Also do they lack the human hero’s and inspiration to cover for the disappearance of the shuttle crews from the media. Nasa’s Plan replaces shuttle with 5 to 10 years of no space flights. Even comparable commercial space flights take at least 5 years to come. With current historic low young Nasa employers numbers (only 20% is between 20-40 years old), waning interest among teenagers (the source of support & brilliant researchers) and more space jobs now being lost, congress is rightly restless. Sure, there are enough great technical challenges, but these will remain unreachable without public interest, short-term.

          Neill deGrasse agrees that we really NEED manned flight, for that interest. Regardless of the goals.

                      Tsunami – Heed the Warnings

                      heed 

                      centuries-old tablet that warns of danger of tsunamis stands in the hamlet of Aneyoshi, Iwate Prefecture, northern Japan. Hundreds of such markers dot the coastline, some more than 600 years old. Collectively they form a crude warning system for Japan, whose long coasts along major fault lines have made it a repeated target of earthquakes and tsunamis over the centuries.

                          Lessons from 11 years of community (my SXSW 2011 talk) from Matt Haughey on Vimeo.

                          A lot of people missed my talk so I recorded it in my office as soon as I got home from Austin. It covers mainly moderation tips and ideas for building tools for more effective moderation.

                          I’ll answer any questions below here on Vimeo.

                                Scientists May Have Accidentally Found Baldness Cure

                                mice

                                Four Re-Haired Mice Injection of a stress hormone blocker into bald mice induces new hair growth and pigmentation. See how they grow hair from row A to row C! UCLA/VA

                                Some of the greatest discoveries in science have been total accidents — Alexander Fleming’s use of penicillin, Wilson and Penzias’ discovery of the cosmic microwave background, etc. Today, scientists announced they’ve once again unintentionally made a monumental discovery: A cure for baldness. OK, only in mice.

                                Researchers at the Salk Institute developed a peptide called “astressin-B”, which blocks the action of CRF, and the teams injected the peptide into the bald mice. They weren’t thinking about baldness at all — they wanted to test whether the astressin had any impact on the mice’s gastrointestinal tracts. The first injection did nothing, so the team gave the mice additional injections over five days, and then measured the effects on the newly de-stressed mice’s colons.

                                About three months later, the researchers came back to do some follow-up GI tests, but they couldn’t find their test mice. They had to check the creatures’ ID numbers to make sure the hairy results were real. Follow-up studies proved it without a doubt, according to a UCLA news release.

                                    It is said that even the most advanced solar energy driven equipment can utilize only 30% of the sun’s energy that reaches the earth. However, the new Johnson Thermoelectric Energy Conversion System promises to convert 60% of the sun’s energy into electrical energy.

                                      Stephen Hawking: Abandon Earth Or Face Extinction

                                      You want to be an optimist, but the truth is that very very few countries stay out of war for more than 100 year. To put it like Einstein: “I do not know what the third world war will be fought with, but the fourth world war will be fought with sticks and stones”. If Hawking and Einstein get it right, playing the weird space-kid might not be such a bad idea afterall? (vid via)

                                            Ascent – Commemorating Shuttle

                                            Photographic documentation of a Space Shuttle launch plays a critical role in the engineering analysis and evaluation process that takes place during each and every mission. Motion and Still images enable Shuttle engineers to visually identify off-nominal events and conditions requiring corrective action to ensure mission safety and success. This imagery also provides highly inspirational and educational insight to those outside the NASA family. This compilation of film and video presents the best of the best ground-based Shuttle motion imagery from STS-114, STS-117, and STS-124 missions. Rendered in the highest definition possible, this production is a tribute to the dozens of men and women of the Shuttle imaging team and the 30yrs of achievement of the Space Shuttle Program.(via)

                                                  Ockels: Duurzaamheid – De regering wil niet en doet te weinig

                                                  s

                                                  Hoewel de regering veel pronkt met termen van duurzaamheid, begraaft Ockels (hoogleraar duurzaamheid) inhoudelijk de verdediging die de regering momenteel voert bij tegenoverstelde daden.

                                                  Puur 5 kolencentrales en 1 kerncentrale bouwen omdat we dan energie kunnen exporteren is wanbeleid. We gaan ermee achteruit: We verspillen geld aan zaken die we niet nodig hebben (energie voorziening voor nederland zelf is al gedekt), verlagen de kansen van duurzaamheids ontwikkeling door zowel gebrek aan investering als oneigenlijke concurrentie die groei blokkeerd..

                                                  Ockels maakte dan ook inhoudelijk gehakt van Liesbeth Spies (CDA) verdediging bij Paul en Witteman afgelopen vrijdag. Als de overheid al een visie heeft, is deze te weinig met daadwerkelijke daden. DOEN. Niet pretenderen. Misschien is hij wel terecht boos dat door het huidige beleid Nederland zometeen het smerigste jongetje van de klas wordt, terwijl eigenlijk niemand dat wil. Hij leidt nu de petitie met een eis voor een DOE visie, Nederland 2050. Teken mee.

                                                  Meer Ockels: Er is energie zat. We winnen het simpelweg te weinig.
