grokson Microsoft’s new small print – how your personal data is abused

Looks like some people are binary editing the Lenovo supplied BIOS to hack in the PCI ID of their WWAN cards.

Your X201 has decent support in the free coreboot BIOS, so if you fancy a weekend project you can ditch the WWAN whitelist altogether:

grokson Microsoft’s new small print – how your personal data is abused

Here's a list of cards supported by ModemManager which works in conjunction with NetworkManager on Linux:

  https://wiki.freedesktop.org/www/Software/ModemManager/SupportedDevices/

It doesn't explicitly call out 4G support so you will have to work backwards.

fyi: some laptop firmware, such as thinkpads, have a whitelist of supported WWAN cards. If you can't find a suitable internal card you can use a USB dongle without restriction.

grokson Yanis Varoufakis opens up about his five month battle to save Greece

> Why do so few people mention that almost 75 percent of Greek pensioners retire before the age of 61?

According to Wikipedia: https://en.wikipedia.org/wiki/Retirement

    | Age             | 55-59 | 60-64 | 65-69 | 70+ |
    |-----------------+-------+-------+-------+-----|
    | Germans working |   61% |   23% |    3% |  0% |
    | Greeks working  |   65% |   18% |    4% |  0% |
    | USA working     |   66% |   43% |   20% |  5% |

65% of Greeks age 55-59 are working, while only 61% of Germans are. More Germans age 60-64 are working than Greeks, but slightly more Greeks age up to 69 are working.

> I also believe that we should hear much more about what the country will do to improve productivity and work harder.

Yes, when will the Germans learn to work as hard as citizens of the USA?

grokson Ask HN: Share your favourite bash/zsh aliases

(Use ^d instead of aliasing x to exit)

Use magit in emacs as a git front-end instead of dozens of git aliases. You can continue to use vi or eclipse or whatever for editing. Use dired in emacs to replace a lot of file manipulation aliases.

Replace all your complicated aliases with ^r reverse search. For example, instead of typing

    sudo dnf --refresh check-update

I type

    ^rche

because 'check' is the most distinct string in that command in my mind, and by 'che' bash has already located the last time I typed it in the history. Save lots of history:

    HISTSIZE=100000                   # Lots of history.
    HISTFILESIZE=100000               # Lots of history in the file.
    HISTCONTROL=ignoreboth            # Ignore entries with leading white space and dupes.
    HISTIGNORE="ls:ll:cd:fg:j:jobs"   # Uninteresting commands to not record in history.
    shopt -s histappend               # Append history to file, don't overwrite.
    shopt -s histverify               # Show expanded history before running it.
    shopt -s cmdhist                  # Store multiline cmds as single

Which directory is hiding all the bytes?

    alias dux='du -x --max-depth=1 | sort -n'

Machines on the local network:

    alias nwho='ping -b -c 2 255.255.255.255 2>&1 | grep "bytes from" | cut -d " " -f 4 | sort | uniq | sed -e "s/://g"'

Set the permissions to allow sharing of files in a directory between users in the same group (probably doesn't work on bsd/osx):

    function rwxs {
        find $1 -type d | xargs chmod u+rwx,g+rwxs,o+rx
        find $1 -type f | xargs chmod ug+rw,o+r
    }

grokson Why I dislike systemd

The difference appears to be that the sudoers file supports the finite set of access checks the authors of sudo anticipated. If you need something more elaborate than that, write arbitrary javascript to the polkit api.

grokson Why I dislike systemd

> Like pretty much anything from freedesktop.org, the documentation is a joke.

  man polkit

Looks pretty good to me. It even includes an ascii-art architectural diagram! Here's the webified version: http://www.freedesktop.org/software/polkit/docs/master/polki...

> polkit doesn't have a textual interface, it only works through D-Bus. This makes it useless for scripting.

polkit(8) and pkcheck(1) describe how to use the pkcheck program. It returns 0 on success (access granted).

> I can't do things like "ok, tell me who can mount filesystems"...

I think that's the nature of the problem domain. polkit seems to be for enforcing arbitrary rules, when the built-in rules of something like sudo can't cope. Therefore: arbitrary code snippets as rules, therefore, no introspection.

However...

> ...or "give me a list of all things that users in the wheel group are allowed to do".

  pkaction | grep mount
  org.freedesktop.udisks2.filesystem-mount
  org.freedesktop.udisks2.filesystem-mount-other-seat
  org.freedesktop.udisks2.filesystem-mount-system
  org.freedesktop.udisks2.filesystem-unmount-others

Gives a list of actions. Use pkcheck to probe for access.

grokson Tax-Free Debt: The great distortion

> What if I had decided to set up the lemonade stand as a corporation instead? The corporation would pay some sort of profits tax (say 20%, so $20,000). There's now only $80,000 for me. But I have to pay personal tax of 30% of the $80k, so in this scenario I walk away with only $56k.

Wages are a pre-tax expense for the corporation.

grokson Tax-Free Debt: The great distortion

> I'm not sure what you mean when you say these people have an 'advantage'?

People who buy-to-let are not in the rental-income business, they are in the business of acquiring property, because property prices are sky rocketing.

People with a job trying to get on the property ladder pay mortgage interest with wages. People with second, third etc. properties deduct mortgage interest as an expense.

grokson The State of Go

> ...a relic of the past when memory and disk space were expensive ... a few megs here and there might actually matter...

The nature of the modern computer is that cpu speed has increased more than memory speed, so if your data doesn't fit into cache your cpu will be do nothing quickly.

Even with shared libraries, this phenomena has such an impact that the Linux kernel now has a memory de-duplication feature (mostly for VMs):

grokson Fedora 22 released

What's the attraction of antique, buggy software which no one is maintaining?

If you're responsible for a power station, satellite etc. then OK, better the devil you know than the possibility of a destabilising bug among all the new features and bug fixes. But for your laptop?

Tip: use ansible to configure your personal machine. Once every six months you boot into the live media, install, reboot, run ansible, reboot, done. You'll spend more time boiling a kettle and drinking a beverage than fettling a new release, and no more time trying to hand install the latest version of package X on a 3 year old base OS.

grokson IndieWeb

> I would love it if everyone could have their own domain name + server - but this isn't practical at this point in time.

You don't need to run your own server. Point the domain name you own at Squarespace (or Wordpress.org, or hosted Wordpress, or any service you like...) for a low-tech, free or low-cost website where you decide what happens.

Move when you change your mind.

1 billion people posting to Facebook is centralised. 1 billion people posting to 1 billion dot-whatever's is decentralised.

From one perspective, moving your Instagram, Twitter and Facebook posts under your own domain is a kind of centralisation, but it's the least interesting perspective, because so what?

The other perspective is that Facebook's (etc.) centralised service determines what you can do, what you see, who can see what you do, and ultimately because we're all products of our environment, defines you. And isn't that kind of sad?
