Meglio giovani o esperti?

A volte mi capita di supportare colleghi in attività di presales in qualità di solution architect e specialista insurance. In uno di questi incontri presso il cliente ho assistito alla presentazione che verteva sulla lunga esperienza delle risorse aziendali in ambito insurance e sull’assenza di junior, che costituiscono elemento di scarsa qualità. E’ stata citata la prima meccanizzazione della compagni X, il primo sistema distribuito di agenzia in Italia per la compagnia Y fino ad arrivare ai progetti sulla diretta per l’assicurazione online z.

Il dubbio che mi porto dietro fino a quando seguivo la delivery come responsabile (e che mi si è riacceso all’incontro) è: meglio avere risorse di esperienza che hanno fatto tante cose o è meglio avere risorse con poca esperienza ma la mente fresca per costruire qualcosa di nuovo? Come per tutto occorre un compromesso, in un azienda sana occorrono giovani e maturi. Soprattutto non è detto che chi ha ottenuto traguardi importanti in passato sia in grado di replicarli in futuro. Questo è un errore che fanno in tanti, essere portati a pensare che un risultato sia replicabile dalle medesime persone.

XIAOMI MIUI issues

I recently bought a new XIOMI  phone with MIUI and I found some bugs:

  • not sending SMS with third party apps
  • google contacts sync missing
  • XIOAMI appstore starts instead of google play by default
  • Missing transations
Not sending SMS with third party apps

This bug is very strange, if you try to send messages using third party apps (not xiomi message app to be clear) you get an error ‘message not sent’. This happens even with the google message app. The solution is somehow tricky, the phone has two sim slot, you just have to switch the sim in the  other sim slot. It seems that only XIAMI message app can use the second slot to send messages.

Google contact sync missing

Having no contacts is on one of the things that make a phone useless. MIUI comes without contact sync app. This app cannot be found on the play store, it is only available through the ‘google installer app’ found on the XIAMI app store. From the google installer app you can install the google contact sync app. Obviously you have to do everything using chinese, not so simple but following some screen-shots you can go through the process.

XIOAMI appstore starts instead of google play by default

There seems to be no way to disable the dafault XIOMI store without rooting the device. Hope somebody will post some suggestions

Missing translations

It is very frequent to receive chinese messages which are very hard to understand.

Connecting to DSL-2740B via ssh

Back again struggling with a stupid issue related to dsl modem.

I was trying to connect to the modem via ssh, but no way to get i work, with ssh i got this log:

Server and client don’t share comunication informatin the right way, so the server decides to close the comunicating (Something that happens even with peoples in real life). So the client needs to force some parameters to set up the propre way to comunicate, in fact chipper and algorithm:

The command line becomes this:

ssh -o Ciphers=3des-cbc -o HostKeyAlgorithms=ssh-rsa,ssh-dss 192.168.1.1 -vv -l admin

To remember this configurations i use the .ssh/config

Host router
HostName 192.168.1.1
User admin
Ciphers 3des-cbc
HostKeyAlgorithms ssh-rsa,ssh-dss

 

Service menu LG 37LF65

Ogni volta mi dimentico la procedura.

Premere 5 sec il bottone ‘menu’ in alto compare la dicitura RGB (che non c’entra nulla con il service menu). Digitare ripetutamente ‘0’.

 

TBS driver new try

Sometime I try to make the fuc…. TDB 6022 card working on linux without making the other card out of work.

Yesterday I tried to build the TBS saa716x driver against the newest linux media, after patching a little bit everything compiles fine the remote works but the TBS6922 frontend which is already compiled in the TBS distribution generates a kernel oops.

Today I tried the other way, I entirely removed the CX23885 from the TBS tree and replace it with the one found in the latest media_build tree. The result was worst, I couldn’t even build the driver because the media_tree used by TBS developers is really tooooooo old. Kernel_version.h reports version

#define V4L2_VERSION 196608

which corresponds to a very very very very old media_tree linux-media-2011-05-31.tar.bz2

So for me by now no way to make the new cards using CX23885 working with the TBS 6922 card, so the brand new TBS6922 card remains off.

I’m still hoping to get and answer from TBS developers….
