Space Wi-Fi + Wired Network (aka please donate some Unifi APs)

by Iain R. Learmonth

Hi, There have been complaints about the wi-fi in the space not being very good. The area of the space is quite a bit larger than the average house that the tiny router was intended to cover. Instead, we could deploy some Unifi access points throughout the space to give better coverage and better spectrum utilisation (using lower power to talk to the AP nearest to you). I've got one access point to put into the space, but ideally we would like 2 or 3. If we got more then we could start covering more of the room that we are in, potentially even giving coverage to people outside the front door which has been requested by those that don't have keys. Thanks to Ana for working with me one afternoon to take apart the ceiling and stick some Ethernet in it, we now have a new rack between the radio desk and the multimedia(?) desk that has wired Ethernet. We've also run patches to the switch in the desk and to the laser printer. Moving PiMPD onto the wired Ethernet would save some bandwidth as streaming music probably does jam up the channel a bit. Everything is there ready for this to happen but I don't know how PiMPD is configured so I didn't touch it. I will add a static IP for the laser printer and get that added to the wiki so that it's super easy (and reliable) to print from wherever you are in the space. Thanks, Iain.

Python User Group

by Robert McWilliam

The next python user group meeting is coming up on 8th Dec. I am (currently¹) planning to be in the hackspace for folks who want to turn up physically again for this one. Talk is "(Christmas) Wrappers and Decorators" if anyone wants to come along. https://ti.to/code-the-city/aberdeen-python-user-group-dec-2021 Thanks, Robert ¹ Plans are back to being vague intentions, with a reasonable chance they're going to get cancelled. -- ________________________________________________________ Robert McWilliam rmcw(a)allmail.net argh.technology Remember when you wanted what you now have?

Re: [57north-announce] python User Group

by Dave Hibberd

You're welcome to swing by whenever we're open! twitter & irc are back to posting when someone opens the space. There is indeed a VT320 in the 'space - it's missing a keyboard currently as Q has borrowed that for their own VT340(?), but the complete setup is working and has been used for various tasks in the last 12 months - most recently in conjuction with a raspberry pi as set decoration for campGND - https://twitter.com/adventureloop/status/1398671740235096064?s=20 -- Hibby MM0RFN On Thu, 11 Nov 2021, at 8:10 AM, Lawrence wrote: > Good meetup last night in the hackspace.

Test

by q＠magicalcodewit.ch

The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't. In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.
