Rohelistest pilvraalidest

-
Minu hea kolleeg Jüri Jaakson kirjutas viimases Microfonis huvitava artikli sellest, et pilvraalid ei pruugi olla üldse nii keskkonnasõbralikud kui neid vahest reklaamitakse. Erisus tuleneb eelkõige sellest, et andmeside jaoks kulutatud energiat ei arvestata pilvraali keskkonna kulu sisse. Loe pikemalt siit.

Kahjuks aga lisandub sellele mõttekäigule üks ebameeldiv nüanss. Nimelt ei ole tänapäeval andmeside keskkonnamõju arvestades praktiliselt üldse oluline see kas äriettevõtted kasutavad kohalikke servereid või kaugetes serveriruumides asuvaid infosüsteeme. Seda seetõttu, et äriettevõtete poolt kasutatav andmeliiklus on täiesti marginaalne võrreldes failijagamise ja interneti-videote vaatamisega. Selle illustreerimiseks mõned numbrid Cisco Visual Networking Indexist:
2010 on äriettevõtete andmeside maht 3,9 exabaiti/kuus, eraisikutel aga 16,5. Eraisikute andmesidest 5 exabaiti/kuus on failijagamine, 4,7 on interneti-video ja 2,3 on veebisurfamine ja data.

Nii, et lahkudes arvuti tagant lülita Youtube välja! :-) Selle teo mõju keskkonnale on võib olla palju suurem kui ettevõtte IT osakonna valik globaalse SAAS lahenduse või oma serveriruumis oleva infosüsteemi vahel.

    Täiesti päri. Ettevõte ei saagi midagi ära teha. Ettevõte on ainult kirje andmebaasis (Äriregistris) ja andmebaasi kirjed ei tee otsuseid. Inimeste käitumise muutumine on võti ning ettevõtte töötaja on vaid üks inimese rollidest kus ta saab otsuseid teha ning oma käitumist muuta.

Misconceptions regarding electric cars

EU's Fit for 55 plan includes quite ambitious emissions reduction targets for the car industry and this has initiated a big discussion in the industry and among thought-leaders. I would like to point out two topics where our thinking tends to go wrong and where looking at the wider picture makes sense Let's think wider than just switching the power source from internal combustion to battery-electric. Here is a photo of one of the first cars made. It is a 1896 Arnold Benz, whose driver Walter Arnold received the worlds first speeding ticket for driving 13km/h with it. As you can see the car looks like a horse carriage minus the horse. It was only a few decades later that cars were considered to be cars and not horse carriages with engines and could therefore be designed differently. At present day we have a similar problem and are stuck in the thinking that an electric vehicle must be a car where everything must be otherwise the same only the engine to be a battery powered elect

2022 - The year of breakthrough of hybrid and remote work. The massive impact this will bring

(Neither ChatGPT, nor any other AI was used to write this article. Photos by me. But the illustrations were created by Midjourney AI. You can find the Midjourney command in Italic at the footer of each illustration.)  In this post I will cover two topics. Firstly, the hybrid and remote work practices and its challenges. Secondly, some thoughts on the huge impact the hybrid/remote work will bring about small-townization. Part 1 - Where we are with hybrid and remote work? A few weeks ago there was a fire drill in the office building of Solita Tallinn. The alarm went on and everybody in the building (the one on the photo) had to evacuate to the street. While waiting on the street for the drill to end we did a small calculation. We calculated that there should be about 800-1000 workplaces in the whole building. However, the "evacuated" crowd was only 150-200 persons strong. So roughly 10-30% of the workplaces in our office building are used. This matches the numbers we are seein

How to move to Estonia Guide (for ICT consultants, specialists....but for others also)

-
The information in this post and the links were updated on 18th of July 2014. In my opinion Estonia is a good place for IT specialists to find a job and work in! Especially in the situation when the (youth) unemployment is rising and in many European countries there is no sign of it easing.  I promoted the idea to the Estonian IT companies in one of my recent posts . With this post I want to give my contribution to the exchange of talent inside EU. I hope this helps at least a few people.  This post is definitely not an official guide, but more of a friendly advice. If you have any questions regarding moving or any important information that could help others then please comment this post!  This post focuses on moving to Tallinn. Tartu, as the second biggest town in Estonia, is also an alternative with Playtech and Webmedia as the biggest IT sector employers there. The first thing you need is a job .  If you are an IT specialist with a university degree there is a good chance
