JEB’s rules of IT

  1. Always have a backup.
  2. Always monitor your backups.
  3. Always backup your monitoring.
  4. Always investigate failures; work out how to monitor it to catch it quicker next time (hopefully before it fails).

Backups without monitoring is no backup at all; if your backups fail, you won’t know until you try to use them.

A note about RAID

Unmonitored RAID 1/5/6/10 is no better than a single disk; as each disk pops, you’ll never notice until the last one goes.

A note about UPS’s

UPS’s fail, OK.

Resilience and cost

Resilient, fast, and cheap; chose any two.

Lies in status messages

Just because something says OK, doesn’t mean it is OK.

HP Dreamscreen 130 – first impressions

It’s a very clean, crisp screen. It’s a neat package, but boy — is it heavy. Even the stylus-like “stick” that screws into the rear of the frame to make it stand up feels like a fishing weight rather than a mere stand.

The default installed firmware was fine – it powered up, and within 30 seconds I was on the wireless network. Like most geeks, first thing was to tell the unit to go and perform a firmware check, which id dutifully did; and thus is downloaded and applied its first update smoothly. Well done, HP.

There is a “home screen” type of interface, with which you can launch any of the apps the literature talks of, or via the configuration of the device, you can tell it to launch a slide show when its idle. Sadly, the “slide show” it does when “idle” (which will be most of the time) is only from local storage. That’s not what I want; when idle, I want it to go and load some online content – photos from Facebook, Snapfish (or Flikr). I basically want it to be a hands-free automatic updating remote display for my online photo album. HP: please address this!!

The Facebook app is very good if you know what pictures you want to show, but for my taste seems to require far too much interaction. Your only choise here is to select which friend’s albums you wan tot see, and then browse their albums. I’d just like to see (or chose) which friends albums are going to be displayed (probably with their name somewhere on the screen, maybe with the caption as well).  Like a “recent photos from FriendA, FriendB, FriendC”, and have the “standby mode” of the DreamScreen just go find recent items from this selection.

Here’s something HP got correct: you can tell it to turn on at one time, and off at another. Great for night time in the bedroom: photo frame goes of at 11pm, and back on at 7am.

Next up – when idle, it would nice nice if we could get the “clock” app to display the time(s)  (with an alpha channel??). Or, for that matter, the weather for the configured location.

Minor bug bear for me; entering a password doesn’t obscure the entered password as you type it from the on-screen keyboard.

There’s a calendar app in here; it shows… a calendar. Wouldn’t this be so much better if you could give it a URL to an ICS or ICAL file and get it to display your calendar appointments? (Don’t forget to set a refresh period, and have the calendar be able to always show the current day/week/month).

More interesting tid-bits as I keep playing with this.

More Acer Revo models

Predictably with Windows 7 almost out (22nd Oct), Acer have a few more models of the Revo in retailers lists: “Acer Revo 3601 Atom 330 Dual Core 4gb 500gb Windows 7 Premium” for £302 inc VAT from Ballicom UK, for example.

Sadly, none of the Dual-core Linux ones have actually started shipping in the UK yet; it’s been weeks now since they were announced!

Alan Turing Petition

Alan Turning is one of the pioneers of the computing industry, working at “Station X”, Bletchly Park during the 2nd World War cracking the Engima codes that helped shorten the war by 2 years.

However as a gay man in the 1940s, he was prosecuted under what is now antiquated, discriminatory laws, and forced by the government to undergo chemical castration. Turning committed suicide in 1954. He was never public recognised for his efforts.

However, a public petition is now underway, with almost 30,000 signatures on it at this stage, to ensure he is given official recognition for his work.

Turing stands as one of the great Computing giants of Britain, along with Sir Tim Berners-Lee (WWW), Lovelace (ADA), etc.
