Each bin defines the absolute maximum number the bin can contain. A bin of 10 will contain numbers up to 10 so 9 and 10 but not 10.1. In other words, the bin contents are less than or equal to (<=) the current bin and greater than (>) the previous bin.
In short a bin contains numbers up to and including the bin’s number but not a fraction over the bin’s number as shown in the examples above.
People usually give their age as rounded down and age limits operate in that way too so a 17.9 year old can’t vote in the UK. If we want to find the number of people aged say 15-18 we need to use the Excel ROUNDDOWN function to make sure someone who is 18.3 or 18.9 appears in a 15-18 bin defined as 18. The previous bin in this example would have to be 14 to capture 14 year olds but not 15 year olds.
A quarter of a million people, or 0.3% of the population of the UK that is alive today, or one in three hundred people in the UK have actually spoken to the Queen.
That figure assumes she spoke to on average 23 new people at each of the 21,000 engagements she attended during her 70 year reign, an average age of her interlocutor of 35, an average lifespan of interlocutor of 75 years (it is 81 in the UK in 2022) and the vast majority of her interlocutors being UK inhabitants.
If we include the 307,000 people she sent a 100th birthday telegram to and the 927,000 couples she sent a 60th anniversary message to that brings the figure up to 2.6 million people in total (alive or dead) she has directly communicated with, though this is an overestimate since there will be overlap between these these cohorts.
Since the written communications were over a period of 70 years, and assuming an average age of the recipient of the written communications of 80, 200,000 could be assumed to still be living, making for up to half a million people in the UK in total who are alive now (2022) having received direct communication from the Queen.
If you have any other thoughts or figures on these estimates please leave a comment below.
Of course, the Queen’s influence was felt by many more people, including myself. Her devotion to duty with good humour and intelligence is just one of the legacies she will leave us with.
If you don’t have the funds or inclination to pay for Vizio or Lucidchart here are a few tools for easily creating a variety of common diagrams, from flow charts to entity relationship (data structure), dependency, UML and presentation graphics. Some don’t require any drawing or layout skills whatsoever and allow you to produce clear professional looking diagrams quickly just by typing concise human readable text – no manual and time-consuming drawing, positioning, resizing, formatting and alignment of objects and connectors!
Archimate is an internationally agreed standard, in the style of UML, that lets one describe pictorially all elements of Enterprise Architecture from motivation like drivers, goals and outcomes to business processes, data, applications, technology, strategy, capabilities, courses of action (like projects and programmes) and deliverables.
Note: if you change the diagram the URL of your edited diagram will also change, which means that you will need to change the diagram URL embedded in any documents that refer to it if you want them to reflect your edits. Of course, if you simply download and include the generated png file in your document you need to change the document whenever you revise the diagram too. The upside is that anyone can revise the diagram in future without having to recreate it from scratch and without needing any software – just internet access. One isn’t even dependent on a particular website since the ‘long string’ from http://www.plantuml.com/plantuml/uml will also work at https://www.planttext.com and one can even install one’s own diagram server:
These can be very powerful by providing insight into the chain of dependencies and relationships within a system. Graphviz allows diagrams in the simple ‘dot’ graph description language to be constructed, shared and saved via e.g.
If you want to show your appreciation for someone’s message or photo in a WhatsApp group chat but don’t want to bother everyone in the group with a notification of your reaction there is now a way by simply long tapping the thing you want to react to and selecting your emoji reaction.
This was a feature request raised over 6 years ago but better late than never I guess!
Top Gun: Maverick wasn’t what I was expecting but was none the less enjoyable for that.
We know from the now 2 year old ‘making of’ trailers how much effort went into capturing the real life flying scenes but for me the visual spectacle didn’t translate to the big screen significantly more than the equivalent scenes from the original.
What did unexpectedly move me was the maturity of the story elements around the characters. Top Gun was almost a coming of age movie about internal conflicts but TG2, rather like Trainspotting 2 finds new material in the things that matter to its now older and somewhat wiser protagonists. Managing relationships in a new mindset with less bravado but more recognition and acceptance of oneself and others and knowing that sometimes we just don’t know.
Yes, the plot may be ridiculous and we can see the manipulations coming but nevertheless I found myself welling up at those moments of mass audience acknowledgement of some of life’s truths and values. Hard work, honesty, tact, camaraderie, courage, compromise, humbleness, mutual respect and understanding.
We may not know the answers but perhaps the message is that sometimes just trusting our instincts is more valuable than thinking, conveyed in the somewhat hackneyed but pithy line:
Like a son, TG2 may inherit some of its forebear’s characteristics but is an entity of its own. Enjoy the ride.
There are a lot of glowing reviews of the latest flagship TV from Samsung, the S95B. Samsung Display’s new and much awaited QD-OLED technology brings extra brightness and colour volume to the inky blacks of regular W-OLED technology, but if you scour the TV reviewer videos, AV websites and shopper reviews you’ll find a surprising number of less than positive aspects reported too.
I’ve summarised those I’ve found so far below but leave a comment if there’s anything I’ve missed.
Starting with a thread of 15 issues based on this TV YouTuber’s findings:
I’ve lumped these problems, plus those from other sources, into a set of categories:
Cheaper LEDs like the Sony X95K and its kin have as many strengths and come in larger screen sizes
Finally, trust your eyes – look at some footage of a real life scene and see which TV looks more realistic and involving. And if the measurements of the TV you prefer are worse than some other TV then the measurements are measuring the wrong things – things that don’t necessarily reflect our perception.
And beware the shills and bots lurking in the comments – you need look no further than those in my last video to see the kind of unsubstantiated hype they come out with!
In a nutshell, this latest evolution of Sennheiser’s Momentum True Wireless Bluetooth earphones offers an adaptive codec that should handle dropouts over distance better, improved ANC and call quality in noisy environments and more secure fit with a popular tuning that emphasises female vocals over the previous generation.
Love: sound quality is among the top tier with, by default, more forward female vocals than its predecessors which, while not to my taste, has a fresher, livelier sound that many may prefer.
Like: comfort, security of fit, the unobtrusive design that sits more flush in the ear, responsiveness of touch controls, lightness, microphone quality, water resistant IPX4 rating, long battery life, Qi charging, removing from the ear automatically pauses a track and replacing it resumes, activating transparency mode automatically pauses a track and deactivating resumes, transparency mode works well, ANC is good for an earphone (tho headphone ANC is much more effective) and does not affect EQ when switched on, the App offers good configuration of touch operation and EQ with my ideal touch configuration for volume (hold), pause (tap) and skip (double tap) by default, and there is no noticeable latency when watching videos.
Dislike: looks which are less distinctive and premium than the previous model, difficulty connecting to a 5y old Windows laptop, the charging port being at the front, the default tuning slightly emphasising upper mids with less bass rumble, single bud use only working with the right bud, there being no multipoint pairing allowing connection to and automatic switching between 2 devices at the same time like your phone and laptop, without unpairing and repairing, Sennheiser make you register to use the Sound Check custom EQ and Sound Zones location based EQ, there is some hiss at the higher levels of transparency mode, and finally value for pure sound quality, which is always my number one priority, is only fair.
I’ve characterised the review this way since a love can outweigh a dislike and vice versa, making simply totting up points in categories like sound quality, comfort, control scheme, security of fit, battery life, connectivity, etc. rather academic. In the final analysis, arguably the best buds are the ones you end up using the most.
The MTW3 maintains the solid foundation of the previous model but with a popular Harman style tuning that brings female vocals more forward in the mix. Such a tuning can emphasise female vocals at the expense of male however the MTW3 remains a good performer with both male (Peter Gabriel’s Heroes) and female (Nitin Sawhney’s Nadia) vocals being involving. They have a tight and deep but marginally less rumbly bass than their predecessor though the sub bass at 3:27 of Hans Zimmer’s “Why so serious?” still comes across as satisfying, if slightly less so than on my reference TWS earphones (that also conveys the plunging into water sounds at the beginning of Dario G’s “Voices” better). Soundstage is also slightly less wide on “Fly Me To The Moon” bringing the higher registers of Sinatra’s vocals more to the foreground.
So sound wise these are a sidestep from the previous generation, with a tuning that I find less natural but that many may prefer.
As someone who rarely uses earphone ANC, for me the new and improved features do not make up for the significant additional cost over alternatives, though admittedly these are much cheaper than the launch price of Sennheiser’s previous equivalent flagship model.
If you’re happy to forego some features like the ANC and top tier transparency, lower profile, more secure fit and auto track pause there are cheaper alternatives from the same manufacturer like the CX400BT and CX series that offer the same level of sound quality in a comfortable form factor.
I’ve reviewed a lot of products and focus the channel on high quality high value audio, technology and wellbeing which, in a nutshell, is bang for buck, so the entirely new level of performance the QD OLED technology of the Samsung S95B promises looks really exciting BUT you need to know there are some uncomfortable truths that almost none of the reviewers are talking about.
Now I love the almost 3d look of OLED and the Samsung S95B quantum dot or QD oled is the latest evolution of OLED technology and looks to offer the most realistic picture yet, combining the impactful brightness of LED with the black levels, depth and gaming response times of OLED.
If you’ve been through the hours of reviews from Digital Trends, HDTVTest, Stop the FOMO, Quantum TV, Tech with KG and others and managed to stay awake you’ll have heard all the excitement about what this new technology, currently only available in the Sony A95K and Samsung S95B, delivers. In a nutshell:
1) Impactful brightness conveying energy due to use of light producing quantum dots rather than regular OLED’s light absorbing coloured filters
2) High Colour volume making the picture pop due to absence of the white sub pixel in traditional WRGB OLEDs that brightens but also washes colours out
3) Perfect blacks with high contrast and depth making the picture look almost 3 dimensional and life like
4) Convincing upscaling of less than pristine content and blur free motion processing.

Some reviewers have gotten very excited and I’d encourage you to check them out.
But we need to get into the technology of these quantum dots. Now bear with me on the science lesson because this will become relevant to the dark truths we’ll get to in a minute, that few reviewers have hinted at.
Colour conversion in QD-OLED displays is done by quantum dots that are placed or patterned at a sub-pixel level over Blue OLEDs.
So, we have a blue OLED emissive layer in the backplane where all pixels are blue. And then green and red quantum dot materials are printed on pixels that need to be green or red.
Just like in regular OLED however, in QD OLED organic materials are the source of the light and these materials wears out. The Blue OLED lights get dimmer with time and over the lifetime of your TV, its display will get less bright.
But this is a new tech right? Well yes its new in that no white sub pixel is employed to increase brightness at the expense of colour purity and there’s no colour filter to reduces brightness, but rather quantum dots which emit photons HOWEVER the underlying light production is still organic and will degrade over time. And there’s the rub.
Now Avforums, a respected av enthusiast website, has over 20 pages of posts on problems due to OLEDs wearing out with sets purchased as recently as Summer 2018, under 4 years ago, and furthermore warranty claims being rejected.
There’s even a whole video on how you can wear your TV out just by watching normal content and I don’t mean screen burn or image retention by having static images frequently on screen. Many people, including me, relate to the problem and there are several comments against this video describing their experiences
Now while the panel will get dimmer over time, that of itself is no big deal since especially with QD oled it was much brighter than traditional OLED panels to begin with, BUT if some areas of the screen typically use certain colours more than others like pink faces in the middle of the screen from news and chat show programs then those areas are going to have pixels that are more worn out potentially causing a colour shift in those areas.
Ah but there’s compensation nowadays I hear you say with pixel shifter and pixel refreshers and screen savers. Well yes, but if you have a patch of red say and shift one red pixel with the red pixel next to it you’ll still have a red pixel being shown and then the only way to compensate is to burn out all the other leds to the same extent making the whole display dimmer each time.
And different rates of wear by different colours, for example with human pink faces typically centre screen can cause those portions of the screen to show a colour cast which is an unpleasant green tinge exactly where faces, which as humans we’re very sensitive to, typically appear. I’ve got another video on how to mitigate the problem, one I experienced myself on a 3 year old Panasonic OLED (tx55hz980b), to make the picture more watchable but it’s a workaround and introduces a wholesale colour shift of the picture so is far from ideal.
And did I mention the price.
Now clearly the QD OLED picture more or less successfully combines the impactful brightness of lcds with the blacks, depth and almost 3d realism of oleds. But the price is double that of competing mini LED, Full Array Local Dimming and OLED TVs so unless you buy into the 100% better view there’s no way it can reasonably be considered worth double the cost of some other still great looking televisions, especially when you consider things like the user experience of the TV operating system, sound quality and picture processing.
So to summarise the S95B may well be a fantastic looking set but bear in mind that
Depending on the content you watch and for how long, because of the technology used and nature of typical TV content, the screen may wear out in such a way that the picture becomes noticeably degraded with jarring patchy colour casts within 4 years so make sure you get a warranty against this – or are rich enough to consider your expensive tv disposable
At double the price of some lesser but still great looking alternatives there may be a new king in QD OLED but for now at least value isn’t its strong suit.
