Re: Parent-Child Hierarchies

Moof — Sun, 13 Jan 2019 04:20:13 -0000

See, told you I’d get something wrong working from a tablet.

I’d have to use CALCULATE([Sales Amount by Product]) in the second measure.

The point here being that both my row and column headers are ragged hierarchies, and I only have one value, that needs to only display when the hierarchy is at that level. If I use SUM(Transactions[Amount]) in both measures, then I will lose the ragged hierarchy display in one of the axes, as I’ll only be using one of the calculations in my value.

If it’s still unclear, I’ll be back at a computer with power BI on Tuesday and can try to come up with a sample file.

I’m on a tablet so I’m having to do this from memory.

Assume I’m doing the simple version:

Sales Amount by Product := IF ( [BrowseDepthProduct] > [MaxNodeDepthProduct],
BLANK(),
SUM(Transactions[Amount])
)

This I could use on any table where the columns are fixed, but the rows have a hierarchy.

For the columns to work, I do the following:

Sales Amount := IF (
[BrowseDepthStore] > [MaxNodeDepthStore],
BLANK(),
SUM([Sales Amount by Product])
)

This I now use as the value in my matrix.

This allows me to see summary for stores in the North, South, East, and Madrid regions, or if I want to expand, I see Bilbao and Santander in the North, Barcelona and Valencia in the East, Sevilla and Granada in the South and the four stores in Madrid. If I expand further, I will see the three stores in Barcelona and two in Bilbao.

This, as well as my hierarchy of products in the rows.

It is just a sum.

If I don’t use two measures, then I won’t get the blanks created when expanding the hierarchy in the columns, which then creates redundant total columns.

Unless you know of a different way to do that?

As an example, imagine a sales matrix, where you have a hierarchy of products all categorized by line type, and product type, and also a hierarchy of stores, also categorized by region, city and store, so two three-level categories.

I place the product category on the rows, and the store category on the columns.

For my Sales Amount Measure, I first create a [Sales Amount by Product] measure, which calculates SUM ( Transactions[Amount] ) for each level, using your current method.

Then I create a Sales Amount measure using the same method as you show, but calculating SUM ( [Sales Amount by Product] )

This way, I can expand and drill down hierarchies on both the rows and columns, and get a good overview by sales region, or drill into individual stores if I wish.

This *does* increase calculation time, but I haven't found it noticeable so far.

This "chaining" of calculations, where you calculate measures based on other measures, and especially filters based on other filters, is worthy of pointing out as a basic pattern for DAX, that it took me a long time to realise, and I feel I'm still learning the language. I'd be interested to know if there are also standard methods to flatten the calculation chain in order to avoid too much calculation.

I hope that clarifies my somewhat hasty comment from earlier.

Sounds great! I’ve also been experimenting with applying this pattern to two-dimensional tables, which I’m doing with two separate measures, one calculating the other. You might want to add the measure chaining pattern to this.

Hi Marco,

I'm using this approach with some column values in a matrix, and the HierarchySlicer custom visual.

It works fine, except that the HierarchySlicer's Select All option selects the entire tree, and thus makes ISFILTERED() return TRUE for all hierachy levels in all contexts. This makes BrowseDepth deeper than MaxNodeDepth on the branches of the treee that don't have as many depths, even if the only the top level is visible, which is obviously incorrect.

I've yet to solve this issue, as I can't work out how to differentiate between "Select all" and "Browse deeper". I'm posting this here as a warning. For the moment, the only workaround I have is to disable the Select All option in the HierarchySlicer

Re: When a table game can think for itself, how do you tell it what to do?

Moof — Fri, 02 Jun 2017 02:59:58 -0000

Gosh... those are two very different options.

Why not both? Put a button on each tile, and have a special Bluetooth tile that can have the game downloaded onto it. Alternatively, have a Bluetooth tile with 6 programmable buttons, or something. Maybe even sell a base set of games, one on each tile of your base set, and sell an add-on Bluetooth tile.

That being said, labelling the bottom of your tiles precludes flipping them over from becoming a game mechanic. Even if they can't communicate while flipped, (though it would be awesome if they could) the added advantage of being able to hide the colour/pulsing as a gameplay mechanic sounds interesting.

The Bluetooth tile is ultimately more flexible because it lowers the bar for game developers. Especially those who want to program them, but find actual hardware too much hassle (yes! We exist!). You could even have a small development toolchain that would upload the game straight onto the Bluetooth tile from your computer. (Will you be able to check the version of the game on the Bluetooth tile somehow? Make sure it's running the latest revision?)

This then opens the idea of an App Store. People can upload the games onto your App Store, and that provides continuing revenue for the game designer and you, although realistically a lot of people will only go for the "free" tier games. Alternatively, you could produce a pipeline whereby a developer can upload their games onto your production chain sive supply chain headache waiting to happen. Plus, not as easy to update if the game is buggy.

Ultimately, the success of a platform like this will depend on the variety of quality games. You're going to have a few that are pretty good packaged with the tiles, but you need to make it easy for others to play on... and it's more open source ethos that way. Bluetooth is definitely the right choice, but it can be one of two distribution methods.

In summary: your developers are going to need something like the Bluetooth option with which to develop anyway. The button press option is much more of a supply chain headache, but can appeal to parents who don't want mobile devices involved. A compromise might be a multi-game Bluetooth tile that can change game at the touch of a button.

Re: Why you really need a scanned copy of your Passport on DropBox (or Evernote)

Moof — Wed, 04 Jan 2012 19:00:04 -0000

And yet my favourite airline here in Spain won't accept a scanned copy of my residence certificate as proof of entitlement to a a residents' discounts. whether presented as a photocopy, or on the ipad, or whatever.

For the record, this is a piece of specially-printed green A4 that is the flimsiest thing one can get away with running through a civil service issue black and white laser printer, and then with a signature stamped onto it with a rubber stamp kept next to said laser printer. The paper happens to say "NOT VALID AS PROOF OF ID" on it. Needless to say, I hardly ever carry it on me, but it still breaks up after a year or so, and is supposedly valid for life.So, yeah, a lot of work needed on mobile-friendly IDs.

Seems to be working so far, better than my current mess of piles of cards...

I've just tried putting some strange cards into the system, see what it comes up with - "cool" avant-garde cards with multiple angles in it, and one in Arabic...

The only downside I see to it is that there doesn't seem to be a way of exporting this data other than into the contact list on the phone. If I had a desktop Rolodex version of it (the way the app scrolls through cards in landscape mode) it'd be much cooler, but I'd settle for some cloud-based vCard thing I can download...

On a similar note. have you checked out LinkedIn's Cardmunch app?

Take a photo of a business card, and it will get transcribed via amazon mechanical turk. So a human being is transcribing it, leaving out much of the guesswork involved in OCR apps. It keeps a picture of the card there, too, for future reference. You can add notes, if you are of that bent, and it automatically tags with when the card was "scanned".

As a bonus, it will also show you key LinkedIn data if that person has their email address set up on LinkedIn, and will invite you to connect to them if you wish.

Finally - it's a separate address list to the one that you main phone has as contact details - which means that you can keep those people you meet once off separate from those you genuinely wish to have on your main phone contact list - but there is an option to upload it straight to the phone if that's what you want.

I've been using it for a few weeks, going though my old piles of business cards - and finally having a clean-out.

I suspect the button is even more revolutionary than that - it'll be a Wi-Fi Protected Setup button:

http://en.wikipedia.org/wik...

this has started appearing on new home routers, too. It's basically a way of not bothering with all that clumsy network key shenanigans. You tell the computer to try to connect, and then when the computer tells you to, you press the physical button on the access point. This is supposrted out fo the box by Windows 7

There's an alternative standard that will display a PIN on the screen, which you then need to input into the computer - it may well be that.

Either way, it'll be much less hassle to use than pulling the battery door off.

Keep in mind that there is another Big Ego in play here - the head of the CMT, Spain's equivalent of OfCom. In fact, most of the key players in the CMT are, unsurprisingly, and officially, ex-Telefónica (now Movistar) employees. Vodafone Spain has a very rough deal on things like interconnect fees as a result.

To a certain extent, MNOs are doing the pay-for-speed already. Certainly in Spain.

The pricing is different for a 42Mbps downlink than for a 7.2Mbps or a 3.6Mbps downlink. Or GPRS.

The catch? You get your maximum speed capped to a certain amount of maximum data, after which your speed goes down. So you can pay e.g. 39€/mo for 5GB of data at 42Mbps, after which your speed goes down to 7.2 Mbps, and then to 3.6 Mbps and so on.

I suspect that is to dissuade people bittorrenting, or equivalent, on the mobile network. This is apparently the world's most pirating-happy country, if you believe the international press.

Oh, and BTW, Telefonica bought Tuenti - a Spanish Facebook Competitor - for 70m€ not too long ago, and it has its own niche market, which is quite successful here. They're about to launch their own MVNO - Tuentimóvil. So, yes, people are accessing TelefonicaBook ;)

There is a lot of internet brou-ha about the "charge for premium access" model you're proposing. Have a Google for Net Neutrality to read up on the pros and ocns of that model - it's not as clear-cut as you think it is.

Re: The International Bacclaureate versus A-levels: which will one help your child shine?

Moof — Sat, 23 Oct 2010 06:19:05 -0000

There is another way to focus this discussion. It seems here that your argument is about what's best for university entrance, which, while a worthy end, is a very career-focussed point of view.

Is it better in this day of knowledge availability on the Internet, relatively short terms in jobs, and where people learn most of their skills on the job, to give a more focussed education to children, or to broaden their minds and give them a much wider field of shallower knowledge form which to draw from? One could argue that it's the university's job to give a science student the required theoretical and technical depth for a job in science and engineering.

As an engineer myself, I was unable to take an a-level in the same subject as my university degree (Computer Science), and didn't feel to be at a disadvantage from my fellow students who had. In fact, I remember being the go-to guy for some people who got firsts as their ability to write essays and technical documents was laughably poor, and I will admit to proof-reading and suggesting sometimes substantial improvements to them.

These days, I perform many more management and directorial roles than technical jobs, and I feel that my broad education is an asset rather than a hindrance.

So, rather than ask "what's easier for the short-term goal of getting my child into university?" maybe ask yourself "what's better for the long-term goal of providing my child with the best preparation he can have to sustain his career well into his forties and fifties?"

Also, what about families that share cars, or people that live from rental car to rental car?

I'd use it to replace my gaily bulging man bag. So things that definitely go in are my iPad and Android phone, along with headsets for both, chargers and cables. Then my two wallets (I tend to carry at least two currencies) and two coin purses, a small paperback for takeoff and landing, a water bottle that I can fill up as I go, tissues, spare batteries, camera, key pass and keys, roll-up rainproof hat, some mints, a couple of public transit maps, and a few snack bars.

And that's only when I'm not travelling ;)

Re: Don’t buy your Android phone for a Froyo update

Moof — Mon, 05 Jul 2010 05:35:27 -0000

Of course, the biggest example here is the Motorola Milestone - released with a massive bug that made the camera unusable over christmas, but on the same day the bugfix was released on the Droid, with an update to Android 2.0.1. People (inlcuding me) bought it in the knowledge that the bug was there and the hope that it would soon be fixed.

Android 2.0.1 finally made it to the Milestone 2 months later, completely buggering up Christmas, given the phonecam didn't work then. It was painful - for some reason known only to Motorola, the rollout was per-country, and took abotu a month to get from the german lot to the British lot. And to add insult to injury, about two weeks later the Droid started getting Android 2.1, and it was a 3-month wait for the rest of us.

Of course, the most annoying thing about the Milestone is the fact that the bootloader is locked down, and will only accept official Motorola ROMs - so we can't even load up a CyanogenMod or something like that. Again, this is unlike the Droid, which can be flashed.

So, er, yeah. Buy a phone for what it *can* do, not what it might be able to do in the future.

And it would actually be a sensible thing to add to reviews of Android phones whether it is known if they're upgradeable to custom ROMs.
