DPG cygnus arms / CMD

 The DPG Cygnus is a gas-lift arm from a decade or so back.  It's since been superceded by another model from the same manufacturer.  I bought a fleet of 10 or so, and they were expensive.  How did they hold up?

This is the full two-joint gas-lift design (there are many other simple metal-on-metal joints on the unit, but two coupled gas-controlled ones).

They sold them in (up-to) 10kg and (up-to) 15kg versions.  At the time, stuff like the 30" dells needed the 15kg version.

You need 4 allen keys to fit and adjust these.  They do supply them, but was it necessary to have so many?  How about one small and one large?

Mechanically, there are issues.  

Monitor rotation involves loosening something at the back, rotating the monitor, then tightening up again at the back.  But this is never exact, so you end up making forcing adjustments when it's tightened.  It's difficult to make just the right adjustment, so you end up going back and forth.  You are certainly not going to be switching back and forth between landscape and portrait.  But it would be nice just to just be able to get it straight and have it stay there.

Tilt has a similar issue, but more insidious.  Even with tight tightening of the relevant hex thing, heavier monitors will tend to creep slowly into a more tilted position, with the top towards the user and the bottom away from the user.  This can happen over several days.

The joint where the main arm's plastic collar fits into the base unit is never a good enough fit, even when the plastic nodule is in the metal dip.  The arm thus always has give from its base, and this amplifies down the length of the arm.

There are also materials quality issues.  

The plastic nodule, that must be put in a metal dip to secure the arm to its base, tends to squidge over time.  It should have been metal.  Once it's squidged, it doesn't go in at all, and the fit at the base of the arm is even worse.

The load-spreaders for under the desk surface have gone rusty.

On the positive side, the VESA plates screw easily to monitors, and then clip on and off easily enough to their mounting point.  But why is this clip not standard?  So if you have a mixture of monitor arms, you end up having to change at the VESA plates and the 4 screws there, not at the clip-on-off plates.

I'm not convinced it's worth the effort compared to just using a monitor on its stand.

the persistent idiocy of "privileged ports" on Unix

TCP and UDP have ports.  These are 16 bit; there are 65535 or so per IP address. These protocols don't care to differentiate between the ports.  Elsewhere, IANA presumes to operate a process to allocate "well-known" ports in the range 1-1023, "registered ports" in the range 1024-49151, and to reserve the remainder, 49152–65535, for "ephemeral" ports.  The caller end has to have a port, which is how replies get back within the virtual connection, and these are conventionally picked from the ephemeral range by the OS's networking stack. The whole idea of ports is ridiculous, because it allows ISPs to arse around presuming to decide which services they will "not allow".  Anything that allows IPSs to do anything other than shift opaque packets will allow ISPs to meddle and break things, and due to the Law of Meddling, if they can, they will.  I am currently working around an issue with Claro, a pretend ISP, blocking port 5060, allocated to SI...

JT "their my" nonsense

Image
Another example of the "your my" nonsense produced by corporations calling customers' things "my" things. Let's mark this for pronouns: In total, I've identified 12 correct pronouns, 6 incorrect pronouns, given from the wrong perspective, and one direct clash between a correct one and an incorrect one, in the form of "their my JT account".  This should be a dead giveaway that something is wrong. As well, observe this perfunctory, bossy, yet passive tone that they take.  "all customers are required" to such and such.  Let's try this.  "All telecoms providers are required to provide ipv6 service".  Oh, that didn't work.  "All entities are required to desist from calling other entities' things 'my'".  Oh, that didn't work either. This is the real pronoun crisis.

easyjet: repeated entry of information they already have

Image
As I observed earlier today, airline web sites are obsessed with making people re-enter information, apparently arbitrarily. The following seems to be required for Easyjet, for an "existing" customer relationship, every time: country of residence selected from big list, involving skidding around on the screen that makes the victim feel sick should be remembered. If it has to be changed, should be type-and-choose victim is taunted with the text "tell us about you", when they thought they had logged in form with the following on one page: business / leisure title, first name, last name, age there is a button to "copy from contact details", but this doesn't do the "age" field.  Since they have my date of birth, they are of course able to calculate my age.  As well, the only values for this field are "18+", "17", or "16".  Is it a deliberate decision, to not fill this field based on the customer data, and to make the...
