In How to Build a Billion Dollar App George Berkowski takes you through the stages of coming up with a mobile app from concept to being a billion pound company. It is based on his story co-founding taxi app Hailo.
As you might expect it is a pretty whistle-stop tour of each stage of the business. However, it provides a good overview with various comments and advice that Berkowski brings from his experience at Hailo. He stresses the importance of getting the product right for the market and how you should be measuring growth, two of the keys to getting a successful product out there.
While it is a good overview, I am not sure how much I am going to take away from it. Compared to something like The Hard Thing About Hard Things which offers plenty of specific and useful advice, this is more of a general guide to the journey. The one thing I did really like was a list of concepts that have universal appeal to humans. This is great for brainstorming ideas from.
I also found it interesting that he recommended having one Scrum Master for around 12-15 engineers. I have worked at a number of companies that do agile and a typical setup in the UK would be one Scrum Master to around 3-5 engineers, a considerably different ratio.
We don’t often repeat recipes in the Worfolk household. There are so many amazing cuisines, cookbooks and ideas out there that we try something new almost every night. However, there are some recipes that are tasty enough, quick enough or reliable enough that they are reused on a semi-regular basis.
As you might imagine from knowing me, I keep them on a spreadsheet. I thought it would be interesting to analysis how many recipes from each cookbook made it onto the spreadsheet and therefore which cookbooks have stood the test of time.
I have linked through to the review, where one exists.
* indicates I am still working my way through this book.
This isn’t an exact science. I re-use some recipes more than others. If anything, Veg Every Day deserves to be higher because I use that a lot, whereas although I have marked Easy One Pot as having a recipe I would re-use, I certainly don’t go for it anywhere near as much.
It is also unfair on some of the books. A lot of the baking books for example are full of amazing recipes that I have yet to try, but one might day and find they are definitely keepers.
Based on these figures, it seems sensible for me to recommend River Cottage and Mary Berry cookbooks. River Cottage consistently does well. The original River Cottage Cookbook isn’t really a cookbook, it’s more of a book about self-sufficiency, so it is not surprisingly it did not do well. The River Cottage Fish Book did not score so well either, but it was fun read. At the other end of the table, both of my favourite River Cottage cookbooks are storming ahead.
Mary Berry is also on the recommendation list because I am working through my second cookbook of hers at the moment and that is also going to score well. Plus they’e excellent for easy meals and dinner parties as they almost always contain instructions for making in advance.
UPDATE: Since writing this, I have finished working my way through Mary Berry Cooks that added 8 new recipes onto my spreadsheet. That puts it in third place behind the two River Cottage books.
Tim Ferriss, the author of the The 4-Hour Work Week, created a TV show called The Tim Ferriss Experiment in which he tried to apply speed-learning techniques to a number of different challenges.
He tries his hand at rock and roll drumming, golf, rally car driving, helping someone start a business and more. He has some success: he plays one song live with a famous band, and makes par on his second hole of a golf course. He also puts a rally car in a tree.
It is somewhat interesting, but I suspect it suffers from the compact format. Each episode is 22 minutes long, which isn’t enough time to really see his journey. He meets an expert, gets a few tips and then completes the challenge. It all looks too easy and you don’t really learn anything. The episode on him helping his friend start her own business is perhaps a little better, but not by much.
The website also has some bonus material for this episode. This is typically a 10 minute interview with the expert, that again falls under the category of somewhat interesting.
As my quest to make a better pizza continues, it occurred to me that when I cook flatbreads I fry them in a dry frying pan, so maybe I could apply the same idea to my pizza.
It turns out that I am not the only person to have had such a crazy idea. A recipe from Pizza Pilgrims details how to do it. I didn’t actually read their instructions, but immediately took heart that it could be done and set about trying it for myself.
Results were mixed. I did get a crispier base, but not as crispy as I wanted it. Maybe the pizza itself was too thick: it is difficult to get it fully cooked all the way through. Also, I only have an electric grill, which is a rubbish kind of grill. I am an adult: give me some flames!
My next plan is to build a clay oven on the balcony.
I ordered some exotic meat from Kezie Foods. They offer a great range of non-mainstream options including horse, kangaroo, camel, crocodile and edible insects.
The problem is that they are delivered via a standard courier. You might wonder how they keep them frozen in transit. The answer seems to be that they do not. They put the products in a polystyrene case that they pack with dry ice. This is supposed to keep everything frozen for 48 hours.
However, when I received their delivery, everything had defrosted. I spoke to their customer services and they were very nice about it, arranging another delivery. The problem is, the exact same thing happened the next time.
Maybe I have somehow misunderstood the definition of frozen. But it feeling exactly like defrosted meat does not seem correct.
So I am giving up. I cooked what I could from the latest batch and will leave it there. At least until I can progress my backup plan of starting an ostrich farm. The products themselves seem good quality: the meat I did manage to eat very good.
The last time I tried to make brioche, it was a total disaster. The recipe book made it out to be this terribly complicated process. The River Cottage bread Handbook dismisses this as nonsense however. Following the much easier to understand instructions, I managed to successfully produce two lovely looking loaves.
Years ago I remember a bus advertisement that read “bus ads work! You’re reading this aren’t you?” The concept recently re-appeared on a billboard on York Road. The question is: do such adverts work?
My guess would be no, because they are so stupid.
Even if you haven’t heard of availability bias, my guess is that most people can work out that those reading it is a self-selecting group. I was reading the billboard but there is no guarantee that anyone else does. In fact, I could have been past a thousand similar billboards and never noticed them, but you would never know if you had. It’s insulting to our intelligence.
Second, I am not sure that anyone who works in marketing is so bad at their job that they use their gut instinct of driving past a billboard to pick their advertising channels, rather than relying on hard data about the audience and conversation rates of different channels.
Finally, if you are going to use this message on a billboard, at least have someone proof read it. You would be barking mad not to.
The apartment building I live in is mixed-use apartments and office space. That means that every now and then there is a fire drill in the middle of the day. I say every now and then: give how little I am home and how often it seems to happen, I would guess at every month. This is really annoying.
We don’t get a warning, so all of a sudden the alarm will go off.
There are two ways you can react to this. One way is to panic. That makes sense, because there might be a fire. But, you are at home, so what state are you in to run out of the building? You might be naked. In the middle of a toilet visit. Asleep. In the shower. In the middle of cooking.
The second is to assume that it is just a drill. They happen so often that this is a good bet. Apartment buildings basically never catch on fire. In fact, it is so rare that even when it happens in Dubai it is a major news story over here. Which is fine, until there is a fire for real and you are burnt alive.
Not to mention that the fire alarm is incredibly loud. If you are of a nervous disposition it probably causes a significant amount of stress, and even if you are not, you are probably running for the exit with fingers in both ears as I saw someone doing today.
Fire alarms are for when there is a fire. That should not have to be something you have to state. It should be obvious. But people keep setting them off and calling them “fire drills”. That should not be acceptable, any more than yelling “fire!” in a theatre is acceptable, unless there is an actual fire.
If you do want to test the systems, that makes sense. But doing it without telling everyone is irresponsible and breads complacence about what a fire alarm actually is.
How often should you bathe your baby? Many parents do it every day, out of a sense of responsibility, or merely because they enjoy it.
It may turn out that I do enjoy it, but right now it sounds like a massive hassle. Recently, I was talking to a friend who said that he did not bathe his baby at all. As long as you clean them properly when changing them, how dirty do they get lying around? Which leads me to the question, how often do you need to bathe your baby?
The evidence is not apparent. The NHS guide, washing and bathing your baby, says that you don’t need to do it every day. However, it offers no guidance on how often you should at a minimum.
Other research suggests that there is a reason you should not bathe your baby every day. Daily baths may contribute to dry skin and eczema. The theory is that bathing removes the protective oils from the baby’s skin, which actually does more harm than good.
This actually fits with the bigger picture. We have known for years that showering every day removes an important layer of oil from adult skin. A new study earlier this year backed this claim up.
Perhaps the answer to the question is, whenever the baby smells.
