Margin Call

Just re-seen Margin Call. What a fabulous film. Wll I say that, it took a second watching to come to that conclusion. It opens with an HR raid on a Bank’s trading floor, and of course they take their phones. It’s one reason why I have two. I don’t depend on my employer to phone a cab home.

It is a fabulous, well informed script, possible except their concentration on current packages and not the severance packages, although the first guy out’s package seems not so generous, although he gets to keep his options. His boss, gets offered a lot more, as do the Traders that perform the fire sale.

There’s a lot of paper and notebooks. The boardroom scene has some fabulous acting. The economics is shite, if you want a film that explains it, see the Big Short or Rogue Trader. …

Compositing

Labour Conference starts on Saturday! I thought I’d document my experience and lessons from the compositing meeting that I attended last year. I was badly stitched up last year and here are some lessons.

The motions to be included in the composite motion will be issued in a CAC report. Read them all, it will be a clue as to the dividing lines between the organisations. Some of them will be identical.

Work out who’s on your side and then make sure they’re represented by someone who cares. In my meeting last year, delegates were voting to exclude words in their own motion.

Take some words into the meeting, the front bench will. In our case, they used five words from our motion, one of which was “the”. Once in the meeting its too late to recover if they propose egregious surgery.

Speaking rights are valuable; you may be able to swap words for speaking rights, it was tried in our meeting but it’s not easy; you can only buy one vote in this way. (Two actually since there’s mover and seconder).

Understand the meeting procedure, Citrine is no help. The Chair, a member of the Conference Arrangements Committee, wasted time, took no amendment motions to re include excluded words and didn;t ask for votes against, since he knew that the majority of the meeting had voted in favour.

The Chair is not neutral, you need to understand their agenda and the new CAC doesn’t take over ’till the end of Conference.

However, and I wish I had known this last year, the meeting can agree to put more than one motion through. You might need to be a large Trade Union to get away with it but at least one of last year’s meetings put through two motions. …

Disloyalty

Boris has written in the Telegraph about the state of the Brexit negotiations, and this is commented in at the FT. The FT leads with the timing, as Mrs. May is planning a big speech in Florence on the EU shortly. Many Tories are also drawn into commenting on loyalty and timing.

On the issue of substance, Boris repeats his usual drivel including contradicting Government policy and re-committing to the £350m/week on the NHS from saved fees. It worries me that the Tories are still looking at avoiding payment of our outstanding fees.

Of the three issues that EU insist are initially dealt with, citizenship rights, outstanding dues and the border with Eire. It’s the money that’s the easiest to comprise on. I believe that short of single market/customs union membership there is no good answer to the border question, but if the Tories want a deal, then they’ll have to compromise on the money even if only to get some room to be awful on citizenship. …

whatsapp

I have just been using Whatsapp for a medium sized chatroom for a month or so.

I’d summarise my views in the table below.

Pro Con
Encrypted on the wire
Real-time
Multi-device
Distributed Admin
No threading, no pinning, no tagging
No rules based archiving/deletion
Tight integration with user’s address book.
High storage usage if using calls, video and images

The good is that it’s encrypted on the wire but not one the device. It’s real time, so better than SMS. You can use a laptop with it’s superior cut & paste to use whatsapp. I’d add as a comment than its user interface can be a bit idiosyncratic. Chatrooms can have multiple admins, which can be good, but can also be misused. (Is this the same as Facebook, which can lead to groups being hijacked.)

The lack of threading, pinning, and tagging, makes conversations hard to follow. (I suppose we could create our own tags and then search on them as text strings, but messages can’t be tagged this way be the recipients, although they can be “starred”.) This can make threads very difficult to track as there will be often a couple of threads concurrent at any one time and once rooms get big the conversations become a bit unmanageable.

The inability to delete messages on the basis of time periods would be useful. I tried Snapchat and found that deletion on reading was a bit too aggressive for my needs.

Your correspondents need to be in your address book, which is reasonable in a 121 conversation, but in a multi-admin chatroom it’s harder to manage and everyone has to do it; it’s a high admin. cost.

Whatsapp stores its messages received on the phone, this includes any real-time voice messages, store and forward voice messages, videos and images, It’s why URLs may be better; I am not sure if the thumbnails are stored locally. People with old phones, large picture and/or music stores may find access to storage constrained. (It reminds me of the old usenet netiquette rules about respecting bandwidth and other people’s devices and costs.

I wonder if slack or google groups are better although Google Groups uses SMTP which is v.hard to encrypt in any usable fashion. …

Deliberation

Here's a little diary on last nights Labour Party General Committee for Lewisham Deptford, its main purpose was to prepare for Conference by submitting a "Contemporary Motion"and hopefully to begin to clear the motions backlog. There were seven motions waiting to be debated, some having being proposed last year. (It's one of the contentions between the current CLP leadership and its opposition that their poor management of time is deliberate and designed to frustrate members making and developing policy. There hasn't been a single ordinary motion debated this year ) . ...

Passwords

I was pointed at an article in the Washington Post on password security. It’s quite long and so I summarise:

  1. Length is better than complexity (More than 12 bytes)
  2. Simple transformations are no help (Don’t use 1st letter Caps and last character as 1 or !, mutt5nut5 is considered very easy.)
  3. Don’t reuse passwords for accounts that you care about! (A corollary is to delete the accounts on services you no longer use.)
  4. Write the passwords down in a secure place if you have too many, or use a password manager. (They are in favour, I am not so sure.)
  5. Don’t use personal facts about yourself (Bdays, Place of Birth, Pet’s names)

They have conducted some volume research by cracking and survey which they reference in the article and built a password checker based on these lessons but using it breaches one or maybe two of the rules I set myself in my Linkedin blog article “Password Vaults”. It’s on the internet, and we can’t read the code; that’s not to say it’s not a useful training tool. …

Search Prominence in Politics

Search Prominence in Politics

In 2011, Andrew Rhodes wrote a paper entitled, Can Prominence Matter Even in an Almost Frictionless Market? He models consumer behaviour in frictionless markets and the role of search engines and their paid placement on the search results page. I have had a look at the article because I am the target of one of Lewisham Labour’s candidates for Mayor’s google ad-campaign. I look at what Rhodes did, and ask a couple of questions about how applicable his model and assumptions are. …
