Chelsea Manning is being tortured

A top United Nations official just condemned the continuing imprisonment of Chelsea Manning as torture and called for her immediate release.

https://www.theguardian.com/us-news/2019/dec/31/chelsea-manning-us-torture-un-official-wikileaks?link_id=3&can_id=9789abc639a66414f4adc2d0eb5989b5&source=email-chelsea-manning-is-being-tortured-2&email_referrer=email_694687&email_subject=chelsea-manning-is-being-tortured

Sign the petition: tell the government to stop torturing Chelsea Manning and set her free.

Chelsea Manning already gave an extensive statement in her 2013 trial and was sentenced to 35 years in prison. After 7 years in prison and 2 suicide attempts she was released in 2017 being commuted by President Obama himself ("Justice has been served."). This case is history.

Criswell Predicts ... IT in 2020

It Predictions

As new year is approaching, there are - inevitably as every year - predictions about what's coming up in IT in the next year.

Unfortunately everything I have read so far is bleeding obvious: Moving to the cloud, AI will be used everywhere, and Python is becoming the most dominant programming language. Without merely continuing the trends from 2019, here are my wild predictions for 2020:

  • With yet another devastating side channel security breach in Intel and AMD processors, all major cloud providers are moving their server hardware to ARM processors.
  • An unnamed whistle blower reveals that the NSA is using quantum computers and AI to profile every single citizen in the world in real-time. Data is retrieved from decrypted TLS connections by quantum computers, and numerous microsatellites orbiting the earth.
  • Chinese smartphones running their own Chinese Open Source operating system are becoming the defacto standard for secure and affordable mobile devices.
  • Large companies like Apple, Google and Microsoft are launching their own space missions to mine natural resources on moon and mars.
  • Large companies like Apple, Google and Facebook begin to span their own microsatellite networks to provide mobile phone and internet services around the globe. National telecommunication companies become obsolete.
  • Deep fake videos are banned by all major industrial countries around the globe. Social media platforms are legally obliged to detect and delete deep fake videos.
  • In a rather controversial press conference Microsoft announces it will discontinue Outlook as an installable email program and urges Windows users to migrate to the corresponding cloud service Office365. Users will have to pay a monthly fee for using Outlook email services. Alternatively Microsoft recommends Mozilla's Thunderbird as an installable email client on local Windows computers.

Chelsea Resists

Chelsea Manning already gave an extensive statement in her 2013 trial and was sentenced to 35 years in prison. After 7 years in prison and 2 suicide attempts she was released in 2017 being commuted by President Obama himself ("Justice has been served."). This case is history.

It is very obvious that she will not testify again. Leave that kid alone.

Chelsea manning just spent another birthday behind bars. Enough is enough. Sign this petition to tell the judge to release her right now.

Seagate 3,5" disk drives

You clearly see that SAS is only used for the highest performance requirements. All other fields of operation are taken over by SATA, which is equal in reliability and enterprise features. If you don't need that extra bit of performance, you should consider using SATA drives especially for NAS or cloud storage. SAS drives offer less capacity and are much more expensive (TCO, not counting IOPS).

If you are interested in SSDs, consider the following:
- Compare DWPD (Drive Writes Per Day) to warranty period
- Compare TBW (Terra Bytes Written) to drive size
- Match your workload to endurance option, there are huge price differences

Open Source Press is closing

Open Source Press is closing down by the end of the year. So this is your last chance to buy some of their books or ebooks from their website. You will get them from Amazon or buecher.de for a while longer, but eventually they will run out of stock too.

I own 13 of their printed books, and they are all of good quality. They offer ebooks too. Some (e)books are in English, but most are German.

Merry christmas and a happy new year.
