Casual Podcast #14 — Note supplementari

Mele e appunti

Ci si risente

Recentemente sono stato invitato a partecipare a un’altra puntata di Casual Podcast di Federico Travaini e Diego Petrucci, per parlare soprattutto di come io riesca a continuare a utilizzare in maniera efficace dispositivi considerati ormai obsoleti, e di come questo sia in parte frutto di una scelta consapevole.

Come per la terza puntata, anche in questo caso ho passato un’ora molto piacevole chiacchierando con Federico e Diego, che ringrazio ancora per la gentilezza e l’ospitalità, e spero sarà un’ora piacevole anche per chi ascolta.

La collezione di Mac

Possiedo parecchi Mac, di varie epoche: dai primi compatti (il Mac 128k originale, un Mac SE, un SE/30, un Macintosh Classic e un Macintosh Colour Classic), a vecchi tower come il Quadra 950 e il Power Macintosh 9500/132 (che negli anni Novanta erano bestioni con prestazioni ‘da professionisti’), a portatili come il PowerBook 100 (il primo vero portatile compatto di Apple), il PowerBook Duo 280c e il PowerBook 5300 (anche quest’ultimo, quando uscì nel 1995, fu considerato uno dei portatili più veloci e capaci dell’epoca, e ricordo che nella versione più completa la macchina costava quasi undici milioni delle vecchie Lire). Fra le macchine di annate più recenti: un PowerBook G3/400 “Lombard”, due PowerBook G4 Titanium, due PowerBook G4 aluminium (un 12″ e un 17″), due iBook G3 ‘conchiglione’ e un Power Mac G4 Cube collegato a un bellissimo Apple Cinema Display da 22″ (il modello in policarbonato semitrasparente uscito nel 1999/2000). Il Mac principale, e unico Mac con processore Intel che possiedo, è un MacBook Pro 15″ di metà 2009, con 8 GB di RAM e un hard disk da 500 GB, usato prevalentemente in configurazione da scrivania con un monitor esterno (un LG Flatron W2243S), una tastiera Apple estesa (l’ultimo modello, piatto, non wireless) e un Magic Mouse.

Ovviamente non ho spazio a sufficienza nel mio appartamento per mantenere tutta questa collezione in mostra. Molti dei Mac citati sopra (e l’elenco non è nemmeno completo…) sono conservati in un armadio, ma tutti vengono periodicamente riesumati per controllarne lo stato di salute. Si tratta pur sempre di una collezione. I Mac che tendo a utilizzare maggiormente sono i G3 e i G4, specialmente i due PowerBook aluminium da 12 e 17 pollici, e uno dei due PowerBook Titanium.

Perché vintage

Non ho riascoltato la puntata del podcast nella sua interezza, ma volevo approfondire il discorso alla base della mia scelta di continuare a utilizzare computer e dispositivi considerati obsoleti.

Per tutti i Mac vintage che uso tuttora ogni giorno vale lo stesso assunto di base: da un punto di vista esclusivamente tecnico, sono macchine obsolete, ma non hanno smesso di essere macchine utili. Almeno per me. Ognuno di questi Mac ha caratteristiche che lo rendono ideale per svolgere un determinato compito:

  • Il PowerBook G4 12″, pur non essendo leggero e sottile come un MacBook Air, rimane il portatile più compatto che possiedo, ed è perfetto per quando lavoro fuori casa e non voglio portarmi appresso un bagaglio ingombrante.
  • Il PowerBook G4 17″ ha la stessa risoluzione del mio MacBook Pro 15″ (1440×900), ma in uno schermo fisicamente più grande e, soprattutto, antiriflesso. Per questo lo utilizzo come macchina per la gestione degli archivi fotografici. E visto che il masterizzatore CD/DVD del MacBook Pro è morto da un pezzo, il PowerBook G4 17″ è anche l’unico Mac ad avere un masterizzatore DVD integrato funzionante. (Il PowerBook da 12 pollici ha un’unità combo, che non masterizza DVD).
  • Il PowerBook G4 Titanium contiene alcuni software che non ho modo di installare altrove (come alcuni dizionari tecnici che legano la licenza a una particolare macchina) e tutta una serie di archivi personali che mi è comodo avere su questo Mac. Per non parlare del fatto che, avendo trovato una batteria più nuova di quella che possedeva originariamente, è al momento il portatile Mac con l’autonomia maggiore (quattro ore abbondanti), e quindi lo porto con me quando so che mi dovrò trattenere molto tempo in luoghi privi di prese di corrente a portata di mano.
  • Il PowerBook G3 Lombard, oltre a essere una macchina ergonomicamente ottima per scrivere, ha la peculiarità di essere uno degli ultimi Mac ad avere una porta SCSI di serie. Questa macchina mi è utile quindi per collegare vecchie periferiche SCSI che utilizzo, fra le altre cose, per recuperare dati da supporti obsoleti e trasferirli su supporti attuali.
  • Uno dei due iBook colorati, il G3/300 blueberry, è diventata la mia macchina Mac OS 9. Uso ancora Mac OS 9 per certe applicazioni e giochi che non si comportano bene nell’ambiente Classic sotto Mac OS X (fino a 10.4 Tiger).
  • Il Power Mac G4 Cube, come già accennato nel podcast, è il Mac vintage che più si integra nel mio flusso di lavoro, servendo come macchina gregaria per tenere sott’occhio tutta una serie di informazioni (Feed RSS, altri pannelli aperti in Safari o TenFourFox, ecc.). Utilizzo il Cube e il suo grande monitor da 22″ anche per guardare film in DVD, dato che, come ho già detto, l’unità ottica del MacBook Pro è andata a farsi benedire. Infine al Cube è collegato un vecchio scanner Canon USB il quale, malgrado abbia quasi 12 anni, fa ancora il suo lavoro e va benissimo per effettuare quelle quattro scannerizzazioni settimanali.

 

Il discorso software

Da un punto di vista software, il ricorrere a Mac datati con processore PowerPC su cui gira al massimo Mac OS X 10.4 Tiger o 10.5 Leopard, non è perché queste macchine abbiano programmi migliori o chissà cosa. In un articolo di marzo 2011, lamentando il fatto che Rosetta (un software che permetteva in Mac OS X 10.6 Snow Leopard di eseguire vecchie applicazioni PowerPC dentro l’architettura Intel) non sarebbe stato parte dell’allora prossimo Mac OS X 10.7 Lion, scrissi:

Giusto per capirci, non c’entra nulla l’appassionato di Mac vintage che è in me. Non è questione di essere affezionati a un passato che non c’è più, o una reazione capricciosa alla filosofia del ‘guardare sempre avanti’ estremamente caratteristica di Apple dopo il ritorno di Steve Jobs nel 1997–98. È questione di non poter più utilizzare comodamente tutta una serie di applicazioni che a suo tempo ho regolarmente pagato (e non poco), e che non ho mai avuto l’esigenza di aggiornare, perché semplicemente vanno benissimo così. Non sto parlando di vecchi shareware (anche se ve ne sono), ma di software come Adobe Photoshop CS, Adobe Acrobat Professional 6, FileMaker Pro 6, Microsoft Office 2004.

Acquistare versioni aggiornate di quei software è una spesa ingiustificata per l’uso che ne faccio, e al tempo stesso mi trovo a utilizzarli con sufficiente frequenza che non è fattibile (almeno per ora) abbandonarli.

Quei software tornano ancora utili per il mio lavoro, e quindi ha senso avere un paio di Mac PowerPC a cui affidarmi quando ho necessità di utilizzarli.

Una domanda che mi viene spesso rivolta quando spiego che uso ancora Mac d’annata riguarda le prestazioni. “Andranno lentissimi” è la reazione comune, specie di chi si ferma alle pure specifiche tecniche. Il Cube ha un processore G4 a 450 MHz. In quanto a mera potenza di elaborazione, si tenga presente che un iPhone 3GS ha un processore da 833 MHz (rallentato a 600 MHz per questioni di risparmio energetico) — da un confronto del genere, il Cube ne esce teoricamente umiliato. Ma confronti provocatori a parte, come sanno bene gli utenti Mac nuovi e vecchi, le specifiche del processore non sono tutto. È l’esperienza utente l’elemento fondamentale, ossia come reagisce il Mac durante l’uso quotidiano. E qui le cose si fanno forse sorprendenti per chi è arrivato al Mac solo adesso e la sua prima macchina è stata un MacBook Core Duo o Core 2 Duo.

Ovvio, in quei compiti che richiedono una certa potenza di elaborazione, un povero PowerBook G4 o un Cube mostrano immediatamente i loro limiti: fare editing video, per esempio, è puro masochismo. I tempi sono eterni, l’interfaccia è poco reattiva, eccetera. Se invece prendiamo in considerazione applicazioni più leggere, come la gestione della posta elettronica, la navigazione del Web, l’ascoltare musica in iTunes, effettuare semplici operazioni di fotoritocco, consultare e annotare PDF, gestire i feed RSS, e simili attività, non c’è questa grande differenza fra il mio PowerBook G4 12″ del 2004 e il MacBook Pro del 2009 (e, da quel che ho visto, anche Mac più recenti). L’altro giorno notavo anzi come sembrasse quasi più scattante Mail.app sotto Mac OS X 10.4 sul Cube che Mail.app sotto Mavericks sul MacBook Pro…

Riassumendo, per operazioni non particolarmente esose di risorse CPU, le prestazioni di un PowerBook G4 o di un Power Mac G4 Cube sono ancora accettabili. (Mi piacerebbe possedere un Power Mac G5 per inserire un ulteriore elemento di confronto: chi lo possiede mi dice che funziona tuttora molto bene anche per compiti più complessi).

Qualche link di approfondimento

Per finire, a chi trova queste tematiche interessanti, ripropongo una serie di articoli da me scritti in passato che trattano nello specifico alcuni dei Mac e dei dispositivi vintage, come il Newton, che uso ancora oggi.

Waterlogue

Briefly

Casually mentioned by Joe Cieplinski on App.net a few days ago, I had to check out this new iOS app, Waterlogue, because I was intrigued by the effect it applied on Joe’s photo. After taking a look at the screenshots attached to the app’s description and taking a tour of the app’s website, I was sold. 

Waterlogue transforms any photo or image into a beautiful watercolour. More importantly, the final result has a rather realistic, natural look, unlike many other ‘photo apps with filters’ that end up giving your photos the same gimmicky, artificial feel.

The developer added a thoughtful detail to the app’s description on the App Store, and since my primary iOS devices aren’t the latest and greatest models, this was a very useful bit of information:

Waterlogue runs advanced image processing software for the highest possible quality watercolor rendering. It produces wonderful images on any device that runs iOS 7, but your rendering times will be shorter on newer, faster devices. Below are the processing times for some typical devices:

  • iPhone 5s.…. 10s
  • iPad mini with Retina display.…. 10s
  • iPhone 5.…. 18s
  • iPod touch, 5th generation.…. 31s
  • iPhone 4S.…. 30s
  • iPad 3.…. 22s
  • iPhone 4.…. 92s

 

(Times are in seconds; Processing used example image “West 14th street” at Medium size) 

I’ve been feeding Waterlogue with many different kinds of photos, and I must say that I tend to prefer how it renders landscape shots, photos of objects and still lifes, rather than portraits. But this is purely personal taste, not a specific issue with the app itself, which is really great.

Below you can see a photo I took with Hipstamatic on my iPhone, and two different renderings created by Waterlogue, just to give you an idea of the different watercolour styles you can obtain. If you like to check out more examples of what this nice app can do, the app’s website has a Made with Waterlogue section.

Things I learnt while restoring my Mac/PC wireless home network

Tech Life

The setup

We don’t live in a huge flat, but my studio and my wife’s studio are far enough from the living-room, where the main router resides, that when I set up the wireless home network nine years ago, I had to add a couple of AirPort Express (802.11g) base stations, one in the living-room, the other just outside our studios in the hallway that connects the living area with the bedroom.

So, the current setup is: 

  • Cisco router in the living-room
  • AirPort Express base station No. 1 connected via Ethernet to the router
  • AirPort Express base station No. 2 used to extend the range of base No. 1

The Cisco is also a wireless router, and broadcasts Home Network 1. The AirPort Express connected to the router share its connection to the Internet wirelessly, creating Home Network 2. Why two different Wi-Fi networks, you ask? Well, there are a lot of devices in my home that connect to the Internet wirelessly, some of them aren’t exactly current technology and don’t support a wireless encryption more sophisticated than WEP, so at times it’s best to have a secondary, closed (the SSID is not broadcast), less secure Wi-Fi network to allow these older devices to temporarily connect.

The incident

Various computers and iOS devices connect to our home network. Most computers are Macs, but my wife uses a Windows PC in her studio, and the other day she was complaining of slow Internet speeds and poor signal reception on her PC. I was puzzled because the Macs in my studio and the PC in her studio are placed at basically the same distance from the AirPort Express base station No. 2 in the hallway. I too had noticed slower Internet speeds on my Macs, but still in the ‘acceptable’ range — websites were slower to load, but they loaded. On her PC, websites stopped loading halfway or didn’t load at all. Plus, every now and then the PC would disconnect from the Wi-Fi network created by the two AirPort Express base stations, due to poor signal.

It was soon clear to me that AirPort Express base station No. 2 had started acting up and was no longer extending the range of base No. 1.

Mind you, this was not the first time. I have to say that my experience with AirPort Express base stations has been overall quite positive, and both these little guys are still working fine after 9 years of 24/7 duty, and they’ve been reliable devices I never had to reset or reconfigure since the first time I set them up in 2005. Occasionally they’ve been acting up, but nothing that couldn’t be solved by restarting either base station or both.

This time restarting AP base No. 2 did nothing. Nor restarting AP base No. 1. Nor both. Nor twice, three or five times in a row.

I repeatedly checked the settings in AirPort Admin Utility and nothing looked out of the ordinary.

It was not a problem with our ISP: the wireless network created by the Cisco router was working.

So I had to reset AP base No. 2 to its factory default settings. Then I used AirPort Setup Assistant to reconfigure AP base No. 2. Now, setting up an AirPort Express base station is a rather straightforward process and Apple software (both the Setup Assistant and the Admin Utility) has a clear enough interface so that any minimally tech-savvy user can do it. I followed instructions carefully, and set up the base station like it was before the incident. 

Still no joy. All devices connecting to the Wi-Fi network created by the two AirPort Express base stations only recognised the one in the living-room (No. 1), and since my wife’s PC was the farthest from that base station, it barely connected. 

After two hours of frustration…

I’ll spare you the details of my tribulations: suffice to say that there was much swearing; much checking and rechecking of parameters that should have been fine as they were yet nothing worked; much restarting and reconfiguring from scratch; much going back and forth from room to room. 

When finally everything started working again, here’s what I’ve learnt from this frustrating experience. Of course, nothing is written in stone and your mileage may vary.

  1. Check the wireless channel on which the two base stations are transmitting. It appears that when you’re using additional base stations to extend the range of the primary one, it’s better if all base stations are transmitting on the same channel.
  2. If there’s a Windows PC connecting to the same Wi-Fi network as Macs, it appears that PCs like channels 1, 6 and 11 best. There’s probably a technical reason for this, but frankly I’m too fed up with this to further investigate. I set both AirPort base stations to channel 1 and everyone’s happy.
  3. Check that the security setting is the same on all base stations:
    Airport admin 2
    For some reason, my AP base No. 2 Wireless Security setting was misconfigured and just said “WPA Personal”.

Only after verifying these three things could the PC connect to the Internet successfully. It was a very frustrating trial-and-error process, and my advice is to remain calm and double check every little detail, as it’s easy to miss something when you’re getting angry because you’re thinking “I should know this stuff, it’s not rocket science, yet for some reason it’s not working.” Also, when everything finally works, take screenshots of all the important settings, so that you can go back to them the next time your base station loses its configuration and you have to set it up again.

If you don’t, I’ll remember it

Briefly

8½

I’ve never been much into animated stills, but the work of the person behind If We Don’t, Remember Me is truly extraordinary and evocative. It’s a poetic declaration of love to what I infer are this person’s favourite movies, and to the art of making movies in general.

I remember finding this tumblelog by chance, back in early 2011 and it quickly became one of my favourite tumblelogs. I remember checking my Tumblr dashboard for updates to see if there was a new animated movie still. Even the stills chosen from movies I knew well were capable of catching me by surprise. IWDRM’s greatness is that it tells a story inside another story.

Then, in 2012 and 2013, I noticed the updates were getting few and far between, and in the last post (a still from Modern Times) the author announced that the project is over, for now. I hope it’s just the beginning of a hiatus, and that someday IWDRM will return.

If it doesn’t, we’ll remember it. Right?

(Look at IWDRM’s Archive page for a bird’s eye view of this beautiful world of stills that subtly, gently, endlessly loop.)

People I added to my reading list in 2013

Tech Life

With regard to reading — both online and offline — I feel my 2013 has been a denser, richer year than 2012. I know for sure I’ve read more books in 2013 than the year before, and as for reading stuff online I’m left with the impression that I’ve found more quality writing overall. Maybe I’m just getting better at instinctively avoiding the bad writing and at filtering out the noise while tuning to the signal.

Fiddling with the feeds

There are geeks who obsess over their software setup and keep rearranging the apps on their phones, tablets, and computers to achieve that perfect combination of frictionless productivity or minimalism-oriented anal-retentiveness or what have you. I tend to rearrange my feeds rather frequently. The main reason I do that is because I don’t want my reading list to get out of control, both in size and in the amount of unread items. My issue with accumulating unread articles is not that I want to reach RSS Feeds Zero at all costs. It’s because, in a way, I think I’m not respecting the people I’ve added to my list of resources. What’s the point of adding someone you find insightful and worth following, if then you don’t read what they write because their website or blog has become just another drop in the ocean of your feed reader?

In the second half of 2013, I further simplified my RSS feed management:

  1. I’ve transferred all the infrequent reads, the rarely-updated sources (the ‘slow feeds’) into the older version of NetNewsWire I keep on my G4 Cube. This version of NetNewsWire doesn’t sync with anything, so it makes sense to use it for those sources I check infrequently and/or are updated infrequently.
  2. The sources I check frequently and those which are updated frequently are managed via my Feedly account, and kept synchronised on the Mac (with ReadKit), on the iPad (with Feedly) and on the iPhone (with My Paper).
  3. I have removed from all my feed readers those sources I end up checking so frequently I don’t even need a feed reader to keep track of them, and I’ve added them to Coast’s screens for quick one-tap access.
  4. I have mercilessly removed from my feed readers all those sources I’ve lost interest in over time, plus all those sources which have let me down, in a way or another (by changing focus and talking more about things I don’t particularly care about; by providing shallower content; by becoming ‘me-too’ blogs; by getting progressively more self-admiring and self-approving; and so on and so forth).

The result of this process is that I have 20 ‘Infrequent Reads’ feeds in NetNewsWire, around 35 feeds in the ‘Hot & always in-sync list’, and 18 bookmarked websites in the Coast browser on the iPad. Considering that in 2011 I had a total of 273 feeds in my feed reader, the current situation after the progressive pruning is pure RSS management heaven.

More people, less portals

In 2013 I noticed I started following people more closely while I found big tech news sites to be less and less appealing. Sure, I read a lot of articles here and there, but most of the time it was because someone on Twitter or App.net had suggested the link, not because I was keeping an eye on that portal’s feeds.

Anyway, without further ado, here’s whom I added to my reading list in 2013.

In the tech sphere (tech commentary, programming, app development, etc.):

  • Harry Marks at Curious Rat — I really like Harry’s honest, direct style. He doesn’t write only tech-related commentary but focuses also on themes related to the process of writing.
  • Nick Heer’s Pixel Envy — I found Nick by following a link on another source (can’t remember who, sorry), and what a great discovery Pixel Envy has been. I loved Nick’s in-depth review of iOS 7 and Retina iPad mini review (and once again I suggest you read his The best photo editing app on the iPhone writeup on The Sweet Setup). He’s another honest voice who always talks from experience and when he has something to say.
  • Raging Thunderbolt — Not frequently updated, but often a refreshing reading.
  • Smarterbits by Shadoe Huard — It’s a recent find, and I like it.
  • Brett Terpstra’s website — You’ll find a lot of interesting resources on Brett’s site, and of course his writing. I never miss his ‘Web Excursions’ link posts. If you’re into all things Markdown, Brett is definitely someone to follow.
  • Stratēchery, by Ben Thompson — Ben’s analyses and insights are always worth your time.
  • Benedict Evans’s website — …same goes for Benedict’s contributions.
  • Waffle — Written by Jesper, “some guy in Sweden” as he presents himself. He often talks about programming and software, and his contributions can get quite technical, but you’ll also find the recipe for making the best Swedish pancakes. My favourite articles are Web browsing like it’s 1999 and Compare Contrast.
  • Techinch by Matthew Guay — I discovered Matthew by reading his great software reviews over at AppStorm. Then I started following him on App.net and finally added his blog to my reading list. I suggest you do the same.
  • Whole & Part by Zac Cichy — The most recent addition (the site is also fairly new), so recent it was already 2014 when I added it. I arrived to it by following a discussion on Twitter and thinking “I like this Cichy guy, I should read more of what he writes.”
  • David Smith’s blog — He’s the developer of Feed Wrangler and I’ve been enjoying his musings about apps and the App Store (read this article or this one, for example).
  • Collin Donnell’s blog — He’s the developer of Pinbook for Pinboard and I discovered his blog only very recently, but I quickly made up for lost time by reading older articles. I really like Collin’s writing. (See for example The Products Apple Doesn’t Have Time to Improve.)
  • Jared Sinclair’s blog — He’s the developer of, among other things, Riposte and Whisper for App.net, and I’m looking forward to using his upcoming Unread RSS reader. I found his blog while browsing for Fifty-Three’s Pencil stylus reviews (Jared has written one) and after reading a few other articles, I decided it was worth keeping the blog in my feeds.
  • Rob Horning’s Internal Exile — Technology, philosophy, food for thought.
  • Jonathon Duerig — I’m adding him to my reading list as a sort of special mention. Jonathon is a developer and has his website where you’ll find more information about his many projects. But my suggestion is to follow him on App.net. He’s a great guy with whom I’ve had many interesting discussions and exchanges. He may challenge your point of view, but what follows is always constructive.

 

Other voices and resources, not strictly related to the tech sphere: 

  • Donovan Bond’s website — Photography above all. If you love Fujifilm’s digital cameras, you’ll want to add his Fuji vs. Fuji project to your bookmarks.
  • The VSCO Journal — I love everything Visual Supply Co. does, and their Journal is a great source of inspiration, especially if you’re into photography and design.
  • Fern Riddell’s Vice and Virtue Blog • The London Music Hall’s 1850–1939 — I’m a bit of a Victorian and Edwardian eras’ fanatic, and I was very pleased to add Fern’s website to my resources. Her About page will tell you all you need to know about who she is and where she comes from. I can tell you she’s smart and witty, and if you like what she writes and the themes she talks about, you should also follow her on Twitter.
  • Messy Nessy Chic — The tag line says it all: Blogging on the off-beat, the unique and the chic. Curious Internet findings, abandoned places, interesting photographs… and much more. Browse the archives, follow the related links at the bottom of every article and go down the rabbit hole. You won’t regret the time you spend on her site.
  • Liz Climo’s tumblr — I love her drawing style and sense of humour.
  • Transit Maps — I’m obsessed with transit maps — especially historical transit maps — and this is a fantastic resource to follow on Tumblr.

 

Is this all? Probably not, and I may update this list in the following days. Oh, and of course I keep reading all the resources and people I found in 2012
