Dag van de architectuur-skate

▼ 20 mei is het in Den Haag de Dag van de Architectuur. (In afwijking van de rest van het land, waar dit het weekeinde van 17 juni is.) Dit kunnen wij natuurlijk niet zomaar voorbij laten rollen, vandaar dat we met de Haagse Royal Skate Night op vrijdag 19 mei een mooie route van zo'n 24 kilometer langs een aantal archtectonisch interessante plekken gaan rollen op inline skates.

Dit is de route op afstandmeten.nl.

Zoals altijd beginnen we om 19.30 uur vanaf het Vredespaleis, zelf natuurlijk een heel bijzonder gebouw uit 1913.

Via de Carnegielaan en de Groothertoginnelaan gaan we dan naar de Segbroeklaan. Zo komen we van de villawijk Zorgvliet uit de jaren 1910 terecht in Duinoord uit de jaren 1890. De Bomen- en Bloemenbuurt is weer wat nieuwer, met moderne platte daken. In de Tweede Wereldoorlog is hier flink afgebroken voor de Atlantikwall, waar later de Segbroeklaan aangelegd is met (uiteraard) na-oorlogse bouw.

Vervolgens doorkruisen we de Bosjes van Pex en maken gebruik van het mooie asfalt in de wijk Bohemen, met architectuur uit de jaren '20. We pikken nog een stukje Laan van Meerdervoort mee en slaan dan af de Aaltje Noordewierstraat op, waar zich de Pastoor van Ars kerk bevindt, waar je zaterdag rondgeleid kan worden.

Daarna pakken we het fietspad richting Nieuw Waldeck, dat in de jaren '70 en '80 gebouwd is. Vervolgens rijden we over het fietspad langs de Mient weer richting het centrum en worden de wijken weer ouder. Via de Kamperfoeliestraat komen we op de Loosduinsekade, waar we de zevensprong passeren met de voormalige bioscoop Capitol uit 1934 waar zich nu Maasbach Wereldzending bevindt. Iets verderop aan de overkant, de Loosduiseweg, zijn oude industrie zoals de melkfabriek van Van Grieken vervangen door nieuwbouw, met name hoge appartementencomplexen.

We maken ook nog even een uitstapje langs het wijkpark de Verademing, waar vroeger een gasfabriek en een vuilverbranding stonden. Aan de overkant van het water zijn nog altijd het grote telefooncentralegebouw en de electriciteitsfabriek te zien. Hier is op zaterdag Rondje Haagse energie – Jane’s Walk en Energiekwartier – Open Bouwplaats.

Vervolgens gaan we via de Lijnbaan en de Prinsegracht naar de Grote Marktstraat, met verschillende interessante gebouwen zoals De Volharding (Randstad) uit 1928 en De Bijenkorf uit 1926.

Daarna komen we langs een aantal van de nieuwe wolkenkrabbers waar ministeries in zitten en gaan we via het centraal station richting Bezuidenhout. Zie de website van de Haagse Dag van de Architectuur voor rondleidingen en meer.

We rijden door de Prinses Beatrixlaan met z'n nieuwe kantoorgebouwen en gaan dan via de Laan van NOI richting het Haagse Bos waar we even stoppen om de Nirwana-flat uit 1929 te bewonderen. Dan is het langs het nieuwe gebouw van de provincie Zuid-Holland en de Mauritskade terug naar het Vredespaleis.

Onderweg zien we nog de achterkant van de kantoorvilla's in het Willemspark en de vele monumenten in de Zeestraat.

Hou skatekalender.com in de gaten om te zien of het doorgaat; als het regent of de straten zijn nat dan wordt de tocht afgelast.

Why now is not the time to jump ship on Apple’s Airport and Time Capsule

▼ On the latest episode of hist podcast, John Gruber complains that Apple’s Airport Extreme and Time Capsule Wi-Fi base stations are woefully out of date and Apple needs to release improved/faster models. Which is not going to happen. However, now is not the time to jump ship and replace your Apple base stations with new and shiny ones from a different vendor.

The argument I’m making here is that you shouldn’t replace your Apple base stations based on the notion that Apple has abandoned them and they won’t release something better in the future. Of course, if you’re unhappy with your Airport Extreme or Time Capsule today and think a different product will serve you better, that’s a different story.

The thing is, Apple’s base stations that were last updated in 2013 still do everything Apple wants them to do today, four years later. They have no reason to update them. The 2013 Airport Extreme and Time Capsule handle the highest Wi-Fi speeds that the latest Macs support: 1300 Mbps 802.11ac. So if you’re not getting the highest possible speeds over the internet, it’s not because your Airport Extreme or Time Capsule lacks raw bandwidth.

Sure, the drive in a Time Capsule tops out at a meager 40 MB/sec and the best third party base stations provide significantly better signal coverage, but those complaints aren’t new and there’s no reason to think that Apple is suddenly going to care about these issues.

It’s entirely possible that Apple disbanded the team that worked on these products because that team simply had nothing to do right now. We have no way of knowing whether this means that Apple is never going to release new Airport Extremes and/or Time Capsules. The current AE/TC were updated to support the then new IEEE 802.11ac standard in 2013. The successor to 802.11ac will be 802.11ax, which should be four times as fast and drive real world bandwidth well into the gigabit range. However, ax won’t be standardized until at least 2018 and probably 2019. So if we’re going to see new Airport Extremes and Time Capsules, it will probably be in 2019.

If you don’t want to wait that long, or believe that Apple isn’t going to release new Wi-Fi base stations, there’s still two good reasons to wait a year or so before switching. Those reasons are 2.5 and 5 Gbps Ethernet and Apple’s new file system, APFS.

Even after a decade, 10 Gbps Ethernet has had a hard time getting traction on the desktop. So those of us who still use wired Ethernet are still stuck on Gigabit Ethernet, which has been available since the early 2000s. The new 2.5 and 5 Gbps Ethernet standards are supposed to fix that, and we’ll probably see reasonably priced 2.5 / 5 Gbps products appear in the next year or so. So unless you have a good reason to upgrade now, it’s probably a good idea to wait for this to shake out.

Last but not least, there’s APFS. If you’re looking for just Wi-Fi networking, Apple’s new file system isn’t very relevant. But one of the big reasons to get a Time Capsule is that the TC allows for simple and easy wireless backups using Time Machine. In the early days, you really needed a Time Capsule to get networked Time Machine backups, but these days most NAS (network attached storage) devices that support Apple’s old AFS protocol for mounting network drives will let you make Time Machine backups.

However, it’s very likely that all of this is going to change in some way when APFS becomes available. Time Machine is built entirely around backing up whole files, while APFS’s snapshot features lend themselves much better to block level backups. It would be a shame to buy a new NAS that allows Time Machine backups today but won’t be compatible with a new version of Time Machine.

So there you have it. If Apple’s Airport Extreme or Time Capsule base stations serve your needs to a reasonable degree today, it makes sense to keep using them for another year or two and see what kind of new base stations and NASes become available and how they work with the Apple ecosystem as it exists at that point.

USB-C dongles, adapters and cables (2)

▼ I'll probably have more to say about some of these later, but here's my list of USB-C adapters, cables and other devices I've collected the past few weeks:

• A 30 W USB-C / 12 W USB-A charger
• A 90 cm USB-C to USB-C cable
• A USB-C to DisplayPort cable
• A USB-C to DisplayPort adapter
• A Thunderbolt 3 to Thunderbolt 2 adapter (from Apple)
• A USB-C to VGA adapter
• A USB-C to HDMI adapter
• A USB-C and USB-A SD card reader
• A USB-C and USB-A 64 GB flash drive
• A USB-C to USB-A adapter
• A slightly longer USB-C to USB-A adapter
• A USB-C to USB A male cable (ordered by mistake, but may turn out useful after all)
• A USB-C to micro-USB cable

Way back in 2008 I got a second charger for my laptop. This means that I can connect my laptop to power both on the couch and at my desk without messing with chargers. Because battery life is so good these days and MagSafe is gone on the new laptops, I plan on using the new MacBook Pro on battery power more often, but I still want that second charger. And that's the nice thing about the move to USB-C: you can now charge using any charger that conforms to the USB Power Delivery (USB-PD) standard. I decided to get a cheap 30 W one, I can always get a bigger one if this one doesn't work or charges too slowly.

The downside is that you now need to buy a USB-C to USB-C cable to connect to the charger separately. I tried to find a fully wired one, so I got this 90 cm one from Aukey which has an e-marked chip. Turns out that 90 cm is pretty short, so I'll probably get a longer one at some later point, and maybe a charge / USB 2 one only.

Obviously I need to connect to external displays, so I got the DisplayPort cable and adapter as well as HDMI. I was thinking about skipping VGA, but the third party one isn't expensive and I'm sure it'll come in handy a few times.

Apple's Thunderbolt 3 to Thunderbolt 2 adapter is pretty expensive, but that way I get target disk mode between my old and new computer as well as 10 Gbps (maybe even 20?) networking between those two, so it's the only reasonable way to transfer files quickly. And I can reuse my Thunderbolt Gigabit Ethernet adapter.

Then there's a USB C/A SD card reader, a USB C/A flash drive (which is super fast by the way, at 150/80 MB/sec read/write), a couple of type C to type A adapters. I also got a five pack of USB-C to USB-A male cables by accident. You have to be really careful with the words "USB 3.0" as this is often used for "USB type A connector".

And last but not least, a type C to micro-USB. This will let me charge my bluetooth headphones, and with the micro-USB to lightning adapter that I already have, I can use it to charge and sync my iPhone and iPad.

But, let's not forget that my previous computers also required various dongles and cables:

• USB superdrive
• Thunderbolt 1/2 cable
• Thunderbolt to Gigabit Ethernet adapter
• miniDisplayPort to DisplayPort cable (third party)
• miniDisplayPort to HDMI adapter (third party) (some of these have been unreliable for me)
• miniDisplayPort to VGA adapter
• miniDisplayPort to DVI adapter (haven't used this one in a few years!)

To add insult to injury, when the new MacBooks with miniDisplayPort came out, it took a month for the dongles to become available so that first month I had to work without an external monitor, like an animal.

At least now the first party dongles are available right away and there are many third party options.
