What happens when a huge number of people share a single grocery store loyalty card? – The Old New Thing

Posted by jpluimers on 2018/01/12

[WayBack] What happens when a huge number of people share a single grocery store loyalty card? – The Old New Thing

An interesting discussion in the comments besides this interesting article observation:

What messes up their data analysis is when two people with different lifestyles swap cards. The system sees that somebody who used to buy yogurt and bulk brewer’s yeast is now buying potato chips and frozen pizzas, and it can’t figure out what is going on.

Is the era of management over? | World Economic Forum

Posted by jpluimers on 2018/01/12

Hopefully the next few years will finally show what the incremental software development and evolutionary management has been trying to advocate since the late 1950s and 1970s: hierarchies do not work and purpose works better for the vast majority than being in a triangle.

The first slide below is from Thoughtworks who has been doing these changes for several decades now.

Traditional hierarchies are giving way to more open and creative workplace cultures.

That’s the only way to cope with complexity as talent dilutes in growing organisations.

Reminder to self: Sort out empty (zero size) Icon? files in Google Drive folder on OS X and Windows

Posted by jpluimers on 2018/01/12

It looks like when syncing folders between Mac OS X (MacOS X?) and Windows, many directories get empty Icon? files have a size of 0 bytes.

None of these directories had custom icons, so I’m inclined to remove them all from the Google Drive folder:

find . -name 'Icon*' -size 0 -print0 | xargs -0 rm

as [WayBack] Didier Trosset answered at [WayBack] How to delete many 0 byte files in linux? – Stack Overflow

Before I do that, I need to read these in more detail:

Proxmox – recovering a Windows 7 machine having “Missing operating system”

Posted by jpluimers on 2018/01/12

This is not what you like when you reboot a VM in Proxmox:

Booting from Hard disk...
Missing operating system

Booting from Hard disk... Missing operating system

Booting from Hard disk… Missing operating system

This case was a Windows 7 UK Professional x64 SP1 virtual machine.

Luckily the ISO is at https://archive.org/download/en_windows_7_professional_with_sp1_x64_dvd_u_676939_201606/en_windows_7_professional_with_sp1_x64_dvd_u_676939.iso via https://archive.org/details/en_windows_7_professional_with_sp1_x64_dvd_u_676939_201606 (later I found out I had the image in my backup vault as well).

I put that one in /var/lib/vz/template/iso so proxmox will automagically provide it in the local storage of iso images.

Now for some screenshots some based on what I learned at [Archive.is] How to use System Recovery Options for repairing Windows Vista or 7 installations:

badssl.com

Posted by jpluimers on 2018/01/11

I wish I had bumped into this when it got released in 2015: [WayBack] badssl.com hosted in the cloud and maintained by two people from Google and Mozilla.

Where ssllabs.com is for checking server-side certificates, this one is for checking clients against many, many (did I already write MANY?) server side configurations both good (with a varying set of security settings like cyphers and key exchanges) and bad.

One of the bad ones is expired.badssl.com which your clients should not be able to connect to without throwing a big error.

Sources are at [WayBack] GitHub – chromium/badssl.com: Memorable site for testing clients against bad SSL configs.

Before using, please read their

Disclaimer

badssl.com is meant for manual testing of security UI in web clients.

Most subdomains are likely to have stable functionality, but anything could change without notice. If you would like a documented guarantee for a particular use case, please file an issue. (Alternatively, you could make a fork and host your own copy.)

badssl.com is not an official Google product. It is offered “AS-IS” and without any warranties.

ACME TLS-SNI-01 validation disabled due to vulnerability – Incidents – Let’s Encrypt Community Support

Posted by jpluimers on 2018/01/11

Now that so many sites depend on LetsEncrypt: maybe it is time for a second one.

We’ve received a credible report of a problem with ACME TLS-SNI-01 validation which could allow people to get certificates they should not be able to get. While we investigate further we have disabled tls-sni-01 validation. We’ll post more information soon.

19 Tips For Everyday Git Use

Posted by jpluimers on 2018/01/11

Great set of tips; I’ve included to intro and ToC here so it’s easier for me to find, but all the details are at [WayBack] 19 Tips For Everyday Git Use. For each paragraph, the ToC lists the relevant command. The article itself also contains some very insightful animated images of which I included one below to get an impression.
