Amazon Countdown sale brings Black Friday deals on Ring cameras, Samsung Galaxy Buds and more
by Henry St LegerAmazon Countdown sale brings Black Friday deals on Ring cameras, Samsung Galaxy Buds and more
Amazon waits for no man

Can't wait until Black Friday UK offers start rolling in? Amazon has kicked off its Countdown sale for those after some warm-up discounts ahead of the massive deals event – with prices already dropping on a variety of smart security cameras, pressure cookers, and Samsung phones and wearables.
It's a small offering to start, and we expect to see more eye-grabbing discounts in the coming days, but if you're after any of the security cameras or home appliances featured here – or the Samsung Galaxy Buds – now may be the time to start shopping.
Amazon's Black Friday Countdown sale will run until November 21, but that will lead straight into the full and official Black Friday and Cyber Monday sales from November 22 onwards. (There will be deals for a while, basically.)
Ring has grappled with some security concerns of its own in recent months, with claims that smart doorbells could be hacked over Wi-Fi, or even that user video recordings were being accessed by Ring employees. But it's not surprising to see the Amazon-owned company pushed in the sales by the online marketplace.
If none of the deals below take your fancy, there are also plenty of other deals appearing across Amazon and other retails, and you can check them out in our Amazon Black Friday, Currys Black Friday, AO Black Friday or John Lewis Black Friday guides.

Abstract: An article devoted to the development of the latest equipment for testing road structures during the diagnostics of roads both in the process of repair and construction, and in the process of operation.
A measuring station for stamp tests of road structures and their layers has been developed, which unites the test equipment into a single automated complex mounted on the base car. This eliminates the need for manual labor of the operator, increases productivity and accuracy of tests, provides the ability to perform multiple loads.
At the same time, any truck or road vehicle can be used to create the load. A measuring unit with special software installed on it is used for registration and processing of measurement results.
The results of laboratory tests of the measuring station, which were carried out in the laboratory of the department of metrological support of measurements of geometric quantities of SE «Ukrmetrteststandard» are highlighted.
The obtained results indicate that the values of measuring force, absolute error and range of measurements of the station of movement of the station meet the regulatory requirements.

Match Play. Double Match Point. How should Red play 54?
pips Red=112 White=148
(CorrectAnswer= 0/0, ErrorScore= 0)
Making the 9-pt looks pretty but can lead to trouble in two ways: if the blot is hit Red can be counter-primed; Red has an extra point to clear when bearing in and a series of sixes could prove awkward.
The simple 14/5 avoids both these problems and Red shouldn’t have too much trouble clearing his mid-point.
14/9, 13/9 is very nearly a blunder at DMP but is downgraded to a mere error in a money game.

This tool will calculate the broad-sense heritability for your trait of interest using a set of C. elegans wild isolates. The broad-sense heritability is the amount of trait variance that comes from genetic differences in the assayed group of strains. Generally, it is the ratio of genetic variance to total (genetic plus environmental) variance.
To obtain the best estimate of heritability, please measure a set of at least five wild strains in three independent assays. These assays should use different nematode growths, synchronizations, bacterial food preparations, and any other experimental condition. You should measure trait variance across as many different experimental conditions (in one block) as you would typically encounter in a large experiment.
Please organize your data in a long format, where each row is an independent observation of one strain in one trait. The columns of the data set should be:
NA values will not be used in broad-sense heritability calculations.


--- layout: archive title: Zulip Chat Archive permalink: /stream/113488-general/topic/type.20class.20inference.20issues.html ---
I have been struggling with type class inference lately. The two main issues are
(1) The error maximum class-instance resolution depth has been reached
(2) In some cases (which are hard to reproduce in minimal examples) I get incredibly long elaboration times (10-30 seconds for a single definition), and I suspect this is completely caused by type class inference (the eventual error I often get is that the type-class max depth is reached).
Problem 1 can be easily solved by setting the class.instance_max_depth
option higher. Problem 2 makes this solution for problem 1 not that attractive, if type class inference then takes even longer.
I have some concrete and some open-ended questions:
Q.1 What does instance_max_depth
exactly mean? Does it mean the depth/height of the search tree, or the total number of instances in the solution? For example, in the following example I have to set the depth to 125, with 124 it fails:
import ring_theory.algebra linear_algebra.tensor_product variables {R : Type*} [comm_ring R] variables {M : Type*} {N : Type*} [ring M] [ring N] variables [algebra R M] [algebra R N] local notation M ` ⊗[`:100 R `] ` N:100 := tensor_product R M N namespace tensor_product set_option class.instance_max_depth 125 protected def mul : M ⊗[R] N →ₗ[R] M ⊗[R] N →ₗ[R] M ⊗[R] N := begin refine tensor_product.lift ⟨λ m, ⟨λ n, _, _, _⟩, _, _⟩, all_goals { sorry } end
Q.2 Does the option trace.class_instances
show the complete trace or does Lean/VSCode truncate the trace somewhere? In traces where I get the max-depth reached error, the highest depth I can find is typically (11)
or (12)
Q.3 In the trace, I see the same type class search over and over again (in a single definition). Is the caching of type class instances failing me, or is something else going on?
Q.4 What are type-class best practices? Do I want to add instances to short-circuit the type class inference? For example, in the example above, if I add the following local instances I don't have to increase the max depth at all:
protected def add_comm_group' : add_comm_group (M ⊗[R] N) := by apply_instance protected def module' : module R (M ⊗[R] N) := by apply_instance local attribute [instance, priority 2000] tensor_product.add_comm_group' tensor_product.module' protected def lmap_add_comm_group : add_comm_group (M ⊗[R] N →ₗ[R] M ⊗[R] N) := by apply_instance protected def lmap_module : module R (M ⊗[R] N →ₗ[R] M ⊗[R] N) := by apply_instance local attribute [instance, priority 2000] tensor_product.lmap_add_comm_group tensor_product.lmap_module
Are there other tips/tricks to keep type-class inference happy/under control?
PS: The reason for the example in Q.1 is that I'm surprised I would need to go to depth 100+.
I just had another problem with type class inference.
I have an instance (with pp.all true
):
_inst_3 : @is_ring_hom.{u_1 u_2} α β (@comm_ring.to_ring.{u_1} α _inst_1) (@comm_ring.to_ring.{u_2} β _inst_2) f
But the trace shows that this instance does not unify with its own type, even with pp.all
true.
[class_instances] (0) ?x_9 : @is_ring_hom.{u_1 u_2} α β (@comm_ring.to_ring.{u_1} α _inst_1) (@comm_ring.to_ring.{u_2} β _inst_2) f := _inst_3 failed is_def_eq
The error occurs here:

DENISE CALLS UP A film review by Clarissa Oon Copyright 1996 The Flying Inkpot
Directed by: Hal Salwen Produced by: Sony Pictures Classics. Cast: Alanna Ubach (Denise), Timothy Daly (Frank), Caroleen Feeney (Barbara). DAn Gunther (Martin). Run Time: 80 minutes Rating: ** out of *****
DENISE CALLS UP
Ever feel you're spending your whole life on the Net (ouch!), eating, breathing and excreting web sites ? That your most meaningful relationships are being formed on the Net? That you get your best sex on the Net ?
If first-time director Hal Salwen could shoot an entire movie of characters typing at their computers, he would. As it is, he settles for characters talking on the phone.  It's a satire - and a sometimes funny one - about how we let handphones, call-waiting and answering machines run our lives.
The problem: DENISE CALLS UP is a movie about an idea. A darn good one, but still an 80 minute-long idea. And despite Salwen's attempt at plots and sub-plots, despite some genuinely funny moments, you can predict the movie's outcome within the first fifteen minutes. You get the drift after a series of shots of characters explaining over the phone why they all couldn't make it for a party - nobody is going to be meeting anybody in this film, they would rather be talking on the phone.
Here's Salwen's plot: while all the characters are in a dysfunctional, telefixated limbo, loud quirky stranger Denise calls up Martin to announce that she is pregnant with his child, courtesy of the sperm he donated to the local bank. As Martin progresses from slamming the phone on her to long phone conversations over the baby's name, his friends - and his friends' friends - get involved, courtesy of call-waiting and double-lines.
In the tigher and more tantalizing sub-plot, Barbara and Jerry are set up on a blind date that neither turns up for. Both profess to have too complicated schedules to ever meet, but they get it going over the phone. With repeated phone sex comes a glitch; what if the other person is simply faking it?
DENISE CALLS UP scores with some inspired moments. Mousy Barbara metamorphoses into a vamp over her cordless, everyone shares the excitement of Denise's delivery through a conference call to her handphone, and Barbara's best friend Gale is killed in a car accident while taling animatedly into another friend's answering machine. (As Gale's overly-chatty aunt recounts, her cordless was knicked into her ear and lodged in her brain.)
But these moments are not enough to sustain the movie. The pace sags, the dialogue drags and not much acting appears to be required of the telephone-touters. And the ending is literally a non-event as expected, everyone is too chicken to turn up for the party Frank throws in Gale's memory despite promising over the phone that they will. We get the point.
The movie appears to be intent on flogging its terribly-'90s statement until they have it coming out of your ears. Pun intended. There's even a on the movie's web site where you can win cellular phones (as if we haven't had enough of these things already). Watch the movie only if you find it philosophy compelling enough for a earful.
THE FLYING INKPOT's rating system: * Wait for the video. ** A little creaky, but still better than staying at home with Gotcha! *** Pretty good, bring a friend. **** Amazing, potent stuff. ***** Perfection. See it twice.

Psalm 5
For the chief musician; with wind instruments.


I'm not so great with memorizing things, but somehow music makes such an impression on me that I've got a nearly savant-like ability to remember the dates when albums were released. It makes sense I suppose: I'm a musical learner after all, and so it checks that I could remember that that STP album was 1993 and that Soul Asylum one was 1992 and that Flaming Lips album was 2002.
This carries over to mean that I have to filter through what music was playing at the time in order to remember personal dates. So, I know that we were living in the house we built in Marengo because of the fact that I can remember listening to "Black Gold" while cleaning the garage. I know that 8th grade was 1991 because, hello Nirvana (plus Nate listening to Nine Inch Nails from the year before).
So, that means that songs get tied to relationships, of course, of course. There are albums or songs that just naturally end up solidly meaning that person at that time in that place, and there's nothing I can do about that (nor would I want to, even). I remember how appalled I was when a friend said to me, "you can't do that you know." I can't not do that -- I can't fathom memories not filtered in this way. Maybe that's another reason why music just means so much.
I'm a veteran of a few long-distance relationships, too, and those songs mailed off to each other, postage to other countries or continents? Even more weight.
This also means, as you might imagine, when a relationship goes south, and stays there, whole albums or songs have to get deleted from the hard drive, figuratively and literally. This doesn't happen often, though it can be pretty significant.
The Streets' "Dry Your Eyes" loosely fits in this category.
[audio:Dry_Your_Eyes.mp3]
I say loosely because I have no idea if she ever has even heard it. I also never really stopped listening to it consciously--but it was still a shock when it came up on random shuffle this week. It's also quite obvious as to why it would work as a post-breakup song the first time you hear the hook:
Dry Your Eyes Mate
I know it's hard to take but her mind has been made up
There's plenty more fish in the sea
Dry your eyes mate
I know you want make her see how much this pain hurts
But you've got to walk away now--it's over
There's more to it than just the chorus, though. More than anything, Mike Skinner really sounds broken. He sets the scene with "In one single moment your whole life can turn 'round," and goes from there, stretching this one moment to an entire song, a temporal shift befitting the train wreck his relationship has become.
 He pleads, begs, even, in a way that you don't usually see in a pop song. "We can even have an open relationship if you must," he says, adding quite the millennial twist to those options that wash over any of us when we feel like he does when he "can't imagine my life without you and me/ There's things I can't imagine doin', things I can't imagine seein.'"
"Dry Your Eyes" came at a time in my life when all that I knew was changing very quickly, and I felt like the rug had been pulled out in many, many ways. I was glad, too, somewhat, but I needed a good cry, and the Streets obliged. "The more I pull on your hand and say/The more you pull away," indeed.
There's no happy ending on this one--and for that, it's perfect.
The Streets: A Grand Don't Come for Free
***
I’ve got about 9000 songs in iTunes, and about ten of them have made the “Perfect” playlist. This is one of them.
***
Fun fact: I discovered today that if you put this song on repeat, it's structured as a neverending loop that seamlessly continues.
And for the record: I got the STP date incorrect. It felt like they had a 1993 presence, I suppose.


Junet Mohamed Claims Kibra Voter Mobilizers Have Received Sh50,000 At Weston Hotel
by Eva NyamburaVoting in Kibra Constituency has kicked off with cases of voter bribery reported in some areas.
Minority whip in the National Assembly and Director of elections in the ODM party Junet Mohamed has also published a list of mobilizers who have received monies meant for voter bribery.
According to Junet, the 13 individuals received Sh50,000 each at Weston Hotel owned by Deputy President William Ruto.
“The following have been given Ksh 50,000 each at Weston Hotel. We already know you and we already planned reciprocal contingency measure. I urge Kibra voters to stay vigilant. Don’t disturb the peace of Kibra people as they vote,” Junet wrote on Twitter.
But State House digital strategist and Jubilee candidate McDonald Mariga’s supporter, Dennis Itumbi dismissed the Suna East legislator’s claims as mere propaganda.
“Hahaaa Mheshimiwa. #LetThePeopleDecide – Propaganda will not deliver victory.”
In the morning, a man was arrested after a mob almost lynched him for allegedly trying to bribe voters.
He was whisked away by police officers.
So far, the late Ken Okoth’s widow Monica Okoth and Winnie Odinga have already cast their votes.
Former Kakamega senator Boni Khalwale has allegedly been chased out of Laini Saba area. He has been drumming up support for Mariga.
The hotly contested race has attracted 24 candidates.
