Civilian Casualties in Afghanistan, 2009 - 2010 איך החיידקים שולטים בנו ברוס גרמן, פרופסור לכימיה מאוניברסיטת קליפורניה דיוויס, חוקר זה יותר מעשור את אחת החידות הגדולות ביותר הקשורות בחלב האם: ההרכב המשונה שלו. 21% מהסוכר בחלב אם עשוי מחומר שאף תינוק אנושי אינו מסוגל לעכל. "במשך שנים האמינו שזו טעות אבולוציונית", אומר גרמן בראיון ל"מוסף כלכליסט". "אבל זה לא ייתכן. חלב אם עוצב על ידי 200 מיליון שנות אבולוציה, תחת אילוצים אדירים. הוא חייב להיות חסכוני מאוד, כי הוא עולה לאם באנרגיות אדירות, וכל רכיב בו אמור להיות מדויק על שבריר האחוז, משום שכל מחסור עלול להזיק לתינוק. 21% מבוזבזים פשוט לא מסתדרים עם זה". לגרמן היה רעיון. כמה שאלות נותרו פתוחות: האם החיידק הזה אכן נמצא בגופם של תינוקות? ד"ר ג'רמי קוניג, ביולוג מולקולרי מאוניברסיטת קורנל, הוא האיש היחיד בעולם שחקר באופן מדוקדק איך קהילת חיידקים צומחת מאפס לטריליון בגופם של תינוקות. עתה לגרמן נותר רק לגלות למה דווקא ביפידו. קצת אחרי שגילינו את האופטיקה, גילינו את החיידקים. מאז ועד לעשורים האחרונים ממש, המדע ראה בחיידקים את הביטוי הפרימיטיבי ביותר לחיים. בעשורים האחרונים התבררה גודלה של הטעות. אז מה עושים?

The Power of Twitter in Information Discovery It surprises me how many really smart people I meet still doubt the power of Twitter. It seems the urge to be a naysayer of Twitter is really strong for some. I think some of this stems from the early days of Twitter when it was presumed that it was a technology to tell people what you ate for lunch. Twitter never seemed to really take the offense in PR and marketing. I guess it wasn’t in their DNA. Right now the most important role to hire in Twitter would be a seasoned marketing professional who could proactively change the conversation about Twitter and educate people about its significance as an information sharing tool. I’ve written extensively about Twitter’s use cases, but it’s biggest power is in information sharing. 1. When we found stuff we liked we “bookmarked” it so that we could come back to the website later. And the company that helped websites publish RSS? But this issue of “how to consistently find the good stuff” is such a hard problem. 2. 3. 4. 5. 6.

Ole's Home My name is Ole Laursen. I'm cofounder of IOLA where I work as a software developer. I have a Master's degree in computer science from Aalborg University in Denmark. More about my professional life at LinkedIn. I live in Aalborg, Denmark with my girlfriend Janne. I used to have a lot of stuff about me here. As you can see from this page, my main interest is designing and programming software. Software Free software I'm maintaining: Flot - a jQuery plotting library for making attractive, pure client-side graphs. Old software Free software I'm more or less not maintaining anymore: The Django plugin django-rendertext - a simple library for generating images with small text snippets in a custom font in a Django web app. Even older software Free software I used to maintain before passing the bucket: gstream - a little C++ wrapper that allowed simple console-like <</>> output/input in standard Allegro graphics modes. I keep a list of good technical books. I can be reached at olau@hardworking.dk.
