I'll not remove my mudguards till summer is here for good

It's a matter of style
Fausto Coppi on a training ride, mudguards and all.

Both my road bikes currently have fenders / mudguards mounted. I've sometimes received negative feedback about this. It doesn't seem to fit with some modern schools of bike aesthetics. Too which I reply: "Who cares?" I'm not going to remove my mudguards till summer is here for good. Even a bit of wet roads here and there will make my bike (and me) look bad. And I'm not that fond of cleaning my bike. Not gonna happen.

Even the greatest cyclists of all times put mudguards on their bikes for training rides. Do you think il campionissimo Fausto Coppi would want a brown stripe down his stylish clothes on his back? It was something different in a race (where the rules disallow mudguards and every bit counts), but on training rides? You think that sweet Bianchi sweater looks good with road grime on the backside? Not likely.

Legs, Sunday Group Rides, and the Mystery of Gorgorr

Left, Right, Left, Right

Early this week I noticed that my legs still have a big inbalance of strength. I've been back on the bike for months now, well, not exactly training, but riding regularly. When you look at my legs, there is no difference in width to be noticed (as the doctors had thought there would). I had assumed the inbalance would even itself out over time. But it didn't...

How I Clean My Bike

I'm not an expert, but at least I'm swiss!

So, yesterday I cleaned my road bike. Since it has decent mudguards (aka fenders), there isn't that much dirt all over the bike, but the gears and chain had a lot of gunk on them. I'm not much into cleaning my bike, I ususally put it off way too long. Now I certainly wouldn't say I'm an expert at bike cleaning. Also there are tons of descriptions what to do around. But this is the procedure I use:

  • Spray WD-40 (see below for note) on gears and chain, and on the pedals.
  • Let soak in, meanwhile prepare a bucket with very hot water and soap.
  • Clean bike with hot water, using car cleaning sponge. At some point I also take the wheels out and clean each in turn. Don't forget the braking surfaces. I use one sponge for the really oily parts, one (cleaner one) for the clean parts of the bike.
  • Flush with clean water.
  • Dry with some pieces of old cloth.
  • Put lots of oil on the chain, some oil on gear derailleurs and pedals.
  • After some hours (better overnight), remove as much excess oil as possible from the chain, it should be pretty dry from the outside, oil is only needed inside the chain. At the end, If there is too much oil on the outside of the chain, it will collect dirt real fast and it will spray oil on the bike, especially on the braking surfaces.

Note on use of WD-40

Keep in mind that WD-40 is considered the devil's stuff on a bike, it is meant only for cleaning, as a degreaser. It's not a good lubricant and it should not stay on. Some people say citrus cleaner is better anyway.

Religious considerations

How to clean a bike is kind of a religious topic. It seems everybody does it a bit different (which is quite ok with me), but it also seems some people feel very strong about it. I'm open to ideas for improvement, tips, warnings about something I do wrong in the comments, but I'm glad if people keep it calm :-)

Is Technical Diversity a Good Thing?

Not everything is equal
Not all gummibears are equal

Speaking to someone who is interested to work for our team, he was surprised that we don't have a standard virtual machine image with all the tools and setup ready. Well... we don't have that. We have a couple of README.txt files, and a setup that each time it's attempted causes a few scratched heads and curses.

But what it also does is ferret out a bunch of problems and bugs each time it happens. "Oh, this library was updated." Usually this is not nice stuff. Stuff that should have been taken care of. Stuff that should have been documented, or even automated. Probably with a bigger team, you'd assign someone to look after this stuff, but we're not a big team. So yes, the procedure to install a new environment can be tedious and time consuming.

But the other reason I like our diversity is that it's basically following the philosophy of what OpenBSD does in developing for a bunch of obscure, strange, and old platforms. It brings out to the light the kind of thing that "works on this platform", but in reality it's just an ugly hack or an -ism of that platform. Making your environment work on a couple of platforms will make things more robust.

(At one point we even tried to go as far as having someone being able to develop on Windows. That simply didn't work out, that "platform" is simply too complicated and needs too many special fixes.)

Am I Lazy?

Let me lay under a tree for a couple of hours and ponder the question
Lying under a tree

In a discussion with a friend over lunch, he told me: "The way you describe your work, one could get the idea that you are lazy!" Indeed I am. Being lazy is a key ingredient to a good programmer. It's what makes us automate tedious, repetitive tasks.

On a further scale, I like things like riding my bike and then sitting somewhere under a tree, pondering all and nothing... and then churr churr my subconscious starts working on those work problems that keep holding the work up.

Being lazy makes me write automated tests for my program code, because a couple of hours writing those tests will save me many, many hours of searching when a problem in that program code appears in a few months. There are many more practical things like that.

Weiss wie Schnee

Seit ein paar Tagen sind die Mandelbäume hier am blühen. Zuerst war noch nichts, dann hatten wir ein paar wärmere Tage, plötzlich sieht man die Mandelbäume überall. Ich kann Mandelbäume sonst schwer erkennen, aber gerade sieht man wo es überall welche gibt, als ob sie sich melden.

Soweit ich mich erinnern kann, ist es das erste Mal, dass ich die Mandelbäume auf Naxos blühen sehe. Früher waren wir erst ab dem Frühjahr hier, da haben wir sie immer verpasst. Dann wäre ich letztes Jahr wohl hier gewesen, aber mit dem Beinbruch habe ich den Februar zuhause in Athen im Bett verbracht.

Als es gestern so stürmte, wurden viele der Mandelblüten schon wieder ausgerissen. Wer seinen Mandelbaum mit etwas Windschutz gepflanzt hatte, ist klar im Vorteil. Zum Teil sind an den Bäumen nur noch auf der einen Seite Blüten dran. Aber bis jetzt gibt es noch genug Blüten zu sehen, und der Wind ist auch schon von Tag zu Tag am abflauen.

Windstärke 9

Es rattert und es knattert

Heute gibt's auf Naxos Windstärke 9 bis 10. Schiffe gehen natürlich keine, es herrscht das sogenannte "απαγορευτικό" (apagorevtiko, das "Verbotene"), d.h. das Hafenamt verbietet, dass Schiffe auslaufen dürfen. Für viele Inselbewohner ist das apagorevtiko ein tiefes, psychisches Trauma, bei jedem kleinen Anstieg der Windprognose wittern sie einen Stopp der Schiffahrt, vor allem, wenn Verwandte, Bekannte, oder eben der Gesprächspartner eine Schiffsreise geplant haben. So häufig kommt es dann aber doch nicht vor.

Im Dorf rattert und knattert es überall. Türen und Fenster knallen, diverse, unbekannte Gegenstände werden umhergeworfen und verursachen scheppernde und knallende Geräusche. Alles was nicht festgezurrt, schwer, oder gut verschlossen ist, fliegt. Als ich vorhin bei der kleinen Kirche am Dorfende vorbeikam, war ein Fenster offen und schlug im Wind. Also bin ich in die Kirche, um das Fenster zu schliessen. Die Nachbarin war aber schon dabei. Gerade als sie hinter mir die Kirche wieder verlassen wollte, riss sich das Fenster wieder los. "Was ist das für ein Wind!", sagt sie noch zu mir.

Unserem Kater passt der Wind überhaupt nicht. Wo er normalerweise den ganzen Tag draussen unterwegs ist, liegt er heute die meiste Zeit im Haus rum, schläft, und langweilt sich. Mach ich die Tür auf, geht er erst ein paar Schritte darauf zu, merkt dann aber was draussen los ist und entschliesst sich dann doch drin zu bleiben. Regen oder sogar Schnee machen ihm weniger aus als der Wind. Mir geht's nicht viel besser, das Velofahren pausiert für heute. Es ist mir schlicht zu riskant. An einem ähnlichen Tag vor 2 Jahren flog mir in Filoti eine Sperrholzkiste um die Ohren und verfehlte mich nur knapp. Aber auch mal zu hause bleiben ist in Ordnung, die nächsten Tage soll der Wind schon wieder abflauen.

So cute

Cute company on the road

One thing to be careful when cycling on Naxos is too look out for flocks of sheep and/or goats on the road. They can be in the middle of the road, blocking your way. Or they can be on the side of the road, and as you pass them, they get scared and try to run away... often straight across your way to the other side of the road. But right now, it's often so funny, because in this season there are a lot of very young animals out there. As seen in the picture, they are torn between being scared, and curious about this strange cyclist guy here. And they are really cute.

Staying with the group

Most of the time they just try to stay with the group, going wherever theyr mommy is going. Yesterday one little goat had to do multiple tries to follow its mother up the side of the road.

Mommy, look how fast I can run

Other times the young ones are even trying to run faster than their mother. Still they are even more planless than the older animals, so watch out!

I tried to be social once

Usually I just try to be funny, with equally lame results

Yesterday as I was shopping in town, the supermarket didn't have any milk (Naxian, real milk, not plastified white water). Luckily we have a "περίπτερο" (periptero, a kiosk) in the next village, which is usually well stocked with said milk. So on my way back I stopped there. Now, since a while there is (apart from Michalis, the owner) a young lady who works some of the shifts there, and as I've heard through a third party, she had gone on a trip for some university exams. As I arrived, I noticed a young lady in the kiosk.

So I picked up my milk from the fridge, and went to pay. As I gave her the money, I nonchalantly said: "So, how was the trip, everything went well?" She gave me a blank look, "You mean Michalis trip? He's been back for some time?" "No, I thought you had gone to university for those exams." Turns out, I had the wrong young lady. Ah, la honte, as the frenchman says! Now there is a young lady who either thinks that I'm pretty ignorant or blind, or both. Well, for once I try to be social, and that's the result. I should probably get back to making cheap jokes instead.

Ταχύτητα στους δρόμους

Μερικές σκέψεις

Οδηγώντας αυτοκίνητο (το τελευταίο καιρό πιο πολύ απ' όσο θέλω) στην Νάξο μου έδωσε μερικές σκέψεις.

Αγροτικά δύο ταχύτητων

Τα αγροτικά αυτοκίνητα εδώ κινούνται σε δύο ταχύτητες: Ή πάνε υπερβολικά γρήγορα, ή πάνε εντελώς αργά. Συνήθως όταν είναι Datsun του προτελευταίου αιώνα, το οδηγεί ο μπάρμπας, και το πάει με 30-40 χλμ/ώρα. Όταν είναι καινούριο (τα οποία είναι και περίπου διπλάσια από μέγεθος) πιθανώς το πάει γαμ...όντας με 80 χλμ/ώρα και είναι κάνας νέος μέσα. Aλλά συμβαίνει και ο μπάρμπας να έχει πάρει καινούριο, οπότε πάλι σαν το σαλιγκάρι πάει.

Το πιο αργό σαφώς είναι πιο ασφαλές. Μόνο που το αργό βάζει όλους τους άλλους στον πειρασμό να τον προσπερνάνε, και εδώ δεν ενδιαφέρονται να βλέπουν μπροστά όταν προσπερνάνε, η όλη ιδέα του να μπορείς να προσπεράσεις με ασφαλή τρόπο (βλέποντας αν έρχεται κανείς, όχι μπροστά από στροφή κτλ) είναι εντελώς άγνωστο εδώ.

Λογική ταχύτητα

Στους δρόμους εδώ θεωρώ μια λογική ταχύτητα να κυκλοφορώ περίπου 50 - 60 χλμ/ώρα, σε σημεία με χαμηλή ορατότητα και 40. Δεν είμαι και μόνος, πολλές φορές συναντώ αυτοκίνητα με παρόμοιες ταχύτητες. Δεν είναι το οδόστρωμα που με περιορίζει, απλά με όλες τις στροφές, μικρούς δρόμους, διασταυρώσεις, ζώα στους δρόμους (τετράποδα) κτλ, χρειάζεσαι χρόνο για να μπορείς να αντιδράς στο απρόοπτο.

Δεν αξίζει να τρέχεις

Μια από αυτές τις μέρες όταν ήμουνα σε βόλτα με το ποδήλατο, με πέρασε ένα αυτοκίνητο γνωστού μου με επικίνδυνο τρόπο, στον Άγ. Προκόπη. Αφού ήταν φορτηγάκι, δεν ήμουνα και εντελώς σίγουρος αν ήταν ο ίδιος στο τιμόνι. Όταν έφτασα στην χώρα, τον πέρασα πάλι. Μόλις κατάφερε να παρκάρει και ετοιμαζόταν να βγει από το αμάξι. Υπενθυμίζω ότι ήμουν στο ποδήλατο, οπότε είχαμε μεγάλη διαφορά ταχύτητας. Παρόλο αυτό ο άνθρωπος δεν κέρδισε και πολύ χρόνο. Αν υπολογίουμε πόσο κερδίζει κανείς να πάει με 60 αντί για 50 στις σχετικά μικρές αποστάσεις του νησιού, ο χρόνος που μπορεί να κερδίζει κανείς είναι γελοίος. Πέραν από αυτό, οι οδηγοί συνήθως ξεγελάνε τον εαυτό τους με τι μέσο όρο ταχύτητας όντως κυκλοφορούν.
