It's the first victory for the French president. Emmanuel Macron, who made the reform of posted workers one of the priorities of his plan for a European reform, was yesterday's winner.
Posted work allows a national of one European country to work in another state while remaining affiliated with the social system in force in his or her country of origin.The issue has highlighted the tensions within the European bloc related to the problem of unfair competition, particularly since the 2004 enlargement to Eastern Europe.
In France, one of the main host countries for posted workers, the revision of the European rules governing this practice has become a symbol of Europe's ability to protect citizens and the economy against social dumping.
And one of the campaign promises made by Emmanuel Macron, who welcomed the compromise reached.
"Reforming the Posting of Workers Directive is essential to enable the European Union to return to the path of economic and social convergence from above, for the benefit of all Europeans," said Nathalie Loiseau, the minister in charge of EU affairs.
Meeting in Luxembourg, the 28 labour ministers already had a compromise on the negotiating table but some points remained to be finalised, notably on the maximum duration of secondment.
It was a sticking point for Paris, which demanded a limitation to 12 months while the European Commission's proposal was based on 24 months.
It is this very question that had derailed an agreement obtained in June. In the wake of his election, Emmanuel Macron rejected the proposal, which offered a maximum period of 24 months. The French U-turn then antagonised a number of countries that were in favour of the proposed period, including Poland.
The French victory over the secondment period, however, was accompanied by some concessions, notably on the date of entry into force of the text, as well as on the transport sector.
While Paris defended a delay in applying the two-year period, several countries called for a transitional period of five years. The final compromise endorsed a period of four years, which pushes the application of the text to at least 2021.
Another amendment is the exclusion of road transport. Elements that irritate Green MEP Karima Delli. "Social Europe is not a map of sectors! I do not accept the concession made on transport", said the MEP, who recalled the slavery-like conditions of certain truck drivers, forced to live and sleep in the motorway car parks.
The subject is now referred to the mobility package on which the European Commission is working.
Emmanuel Macron met with Spanish leader Mariano Rajoy at the last EU summit in Brussels on October 20 to try to convince him of the need to include this sector in the framework of the new directive. But on this aspect, Spain and Portugal have joined the position of the Eastern countries, which called for a specific text taking into account the mobility issues of the sector.
The final agreement thus provides that the new directive does not apply to the transport sector until an agreement on the 'mobility package' is reached.
In the final vote, only a handful of countries voted against the compromise: Poland, Hungary, Lithuania, and Latvia. Several Eastern European countries hostile to the position defended by Paris finally aligned themselves after the negotiations (Romania, Bulgaria, Slovakia, Czech Republic), allowing the text to be adopted by a qualified majority.
The agreement must now be finalised between the Council and the Parliament, which adopted its position on the dossier on 16 October.
Emmanuel Macron, who has engaged a large part of his political capital on this issue, will now have to keep up the momentum.
After the speech at the Sorbonne, the French president has presented a long list of reforms at European level: a tax on financial transactions, reform of the eurozone, transnational lists, and taxation of digital companies. So many dossiers on which he will have to win over his European partners.
EU ministers yesterday night (23 October) struck a compromise after marathon talks about low-cost labour from Eastern and Central Europe, a decision affecting workers posted temporarily to more affluent bloc members.
Why not the E.U. 12 in a real Unit instead being oppressed by the other not willing to go for .
A disaster with Balkan states inside non compatible sectors .
Mr. Macron is doing his work but the lack of a federal administration makes it impossible this kind of EU to be managed properly and we are seeing it . Most are tired with their business as usual à l'allemande ….

Le HMS P36 (Pennant number: P36) était un sous-marin de la classe Umpire de la Royal Navy. Il a été construit en 1941 par Vickers-Armstrongs à Barrow-in-Furness (Angleterre).

Conception et description
Le troisième lot de sous-marins de classe U a été légèrement élargi et amélioré par rapport au deuxième lot précédent de la classe U. Les sous-marins avaient une longueur totale de 60 mètres et déplaçaient 549 t en surface et 742 t en immersion. Les sous-marins de la classe U avaient un équipage de 31 officiers et matelots.

Le P36 était propulsé en surface par deux moteurs diesel fournissant un total de 615 chevaux-vapeur (459 kW) et, lorsqu'il était immergé, par deux moteurs électriques d'une puissance totale de 825 chevaux-vapeur (615 kW) par l'intermédiaire de deux arbres d'hélice. La vitesse maximale était de 14,25 nœuds (26,39 km/h) en surface et de 9 nœuds (17 km/h) sous l'eau.

Le P36 était armé de quatre tubes lance-torpilles de 21 pouces (533 mm) à l'avant et transportait également quatre recharges pour un grand total de huit torpilles. Le sous-marin était également équipé d'un canon de pont de 3 pouces (76 mm).

Carrière
Le , en patrouille dans le golfe de Gascogne, le P36 attaque un sous-marin allemand (U-Boot)  avec des torpilles au sud-ouest de l'île de Belle-Ile. Les torpilles ont manqué leur cible qui pouvait être un des U-133, U-552, U-567 ou U-577.

Le , le P36 lance quatre torpilles contre les croiseurs lourds italiens Gorizia et Trento dans la mer Ionienne, à environ 90 milles nautiques (170 km) à l'est du Capo Spartivento, en Calabre, en Italie. Aucune des torpilles n'a touché. Deux jours plus tard, le P36 torpille et endommage le destroyer italien Carabiniere au large de Tarente.

Le , le P36 se trouvait sur une jetée du port de Tas-Sliema' à Malte lorsque la Luftwaffe a attaqué le port. Une grosse bombe provenant d'un avion du Sturzkampfgeschwader 3 atterrit suffisamment près du sous-marin pour le trouer et il commence à couler. Malgré des efforts désespérés pour sauver le sous-marin, il se retourne et coule.

Après la perte du P36 en 1942, certains membres d'équipage survivants ont embarqué à bord d'un autre sous-marin, le HMS Olympus, à destination de Gibraltar. Peu après avoir quitté Malte le , lOlympus heurte une mine et coule. Les neuf survivants des 98 passagers et membres d'équipage ont nagé sur une distance de 7 milles nautiques (11 km) jusqu'à la côte maltaise.

Le P36 n'a été renfloué que le  et s'est ensuite échoué au large de Malte le .

Gliders or sliding disks are an awesome addition to basic moves and are also super convenient! Gliders put a unique spin on exercises by forcing your muscles to be under constant tension the whole time. For example, in a reverse lunge, rather than picking up your foot to step back, you will keep your foot on the glider the whole time as you slide back, forcing your leg muscles to stay engaged. Gliders can also help improve balance and also offer a low impact alternative to exercises. Try the exercises below and notice the difference. You are guaranteed to see an improvement of your balance and stability in just a few weeks!
Reverse Lunge: Place one foot on the slider. Slowly step back, dragging the slider along beneath your foot. Repeat on the opposite side.
Plank Oblique Crunch: Start in a plank position with both feet on Gliders. Slowly draw your right leg forward until your bent knee touches the side of your right elbow. Slowly go back to plank position and do the same on the opposite side.
Mountain Climbers: Similar to the plank oblique crunches, start in a plank position with both feet on gliders. This time, alternating legs, draw the knee in towards your chest quickly and alternate as fast as possible!
Hamstring Curl: Laying on your back, place your heels on the gliders. Lift your hips, and bending at the knee, draw your feet in towards your body.
Plank Jack: Start in a plank position with both of your feet on gliders. Keeping your legs straight, slowly split at the feet moving your feet out horizontally. Bring back in and repeat.

Q: Avoiding measurability due to independence Let $(\Omega , \mathcal F , \mathbb P )$ be a probability space and $E$ polish space. Now assume that for every $x\in E$ there an event $A_x \in \mathcal F$ is given. Further let $X:\Omega \to E$ be a random variable such that $\sigma (X) $ is independent from $A_x$ for every $x\in E$. Assume that there is a set $N \subset E$ such that $\mathbb P (A_x) = 1$ for all $x \in E \setminus N$ and $\mathbb P (X \in N ) =0 $.
Furthermore, we can assume that $\omega \mapsto 1_{A_{X(\omega)}}(\omega ) $ is measurable.
Can we deduce that $\mathbb P (A_X) = 1 ?$
Of course, Fubini's theorem comes into mind. One is tempted to write
$$\mathbb P (A_X) = \int_{E} \mathbb P (A_x)  \mathbb{P} (X \in d x)=1,$$
but the measurability of $x\mapsto \mathbb P(A_x) $ was not a given assumption.
I will try to give an example for an application: Assume that $X = (X_i)_{i\in \mathbb N}$ is a sequence of i.i.d. random variables with values in $\mathbb R$ and $(Z_i)_{i\in\mathbb N}$ is a sequence of i.i.d. standard normal distributed random variables independent from $(X_i)_{i\in\mathbb N}$. Thus $E = \mathbb R ^\mathbb N$ and now define for every $x\in E$ the events
$$A_x = \{ L_x := \lim_{n\to\infty} \frac 1 n \sum_{i=1}^n Z_i 1_{(-\infty , 0]}(x_i) + Z_i^2 1_{(0,\infty)}(x_i) \text{ exists and is equal to }  \lim_{n\to\infty} \frac 1 n \sum_{i=1}^n 1_{(0,\infty)}(x_i) \} $$
$1_{A_X}$ is measurable and on the set $E\setminus N := \{x\in E: \lim_{n\to\infty} \frac 1 n \sum_{i=1}^n 1_{(0,\infty)}(x_i) \text{ exists}\}$ we have $\mathbb P(A_x) = 1$. In this case we could argue that $x\mapsto 1_{A_x}$ is measurable, but can we conclude without it that $\mathbb P (A_X)= 1$?

One of the first steps in planning a research study is the choice of study design. The available study designs are divided broadly into two types – observational and interventional. Of the various observational study designs, the descriptive design is the simplest. It allows the researcher to study and describe the distribution of one or more variables, without regard to any causal or other hypotheses. This article discusses the subtypes of descriptive study design, and their strengths and limitations.

In our previous article in this series,[1] we introduced the concept of "study designs"– as "the set of methods and procedures used to collect and analyze data on variables specified in a particular research question." Study designs are primarily of two types – observational and interventional, with the former being loosely divided into "descriptive" and "analytical." In this article, we discuss the descriptive study designs.
What Is a Descriptive Study?
A descriptive study is one that is designed to describe the distribution of one or more variables, without regard to any causal or other hypothesis.
Types of Descriptive Studies
Descriptive studies can be of several types, namely, case reports, case series, cross-sectional studies, and ecological studies. In the first three of these, data are collected on individuals, whereas the last one uses aggregated data for groups.
Case reports and case series
A case report refers to the description of a patient with an unusual disease or with simultaneous occurrence of more than one condition. A case series is similar, except that it is an aggregation of multiple (often only a few) similar cases. Many case reports and case series are anecdotal and of limited value. However, some of these bring to the fore a hitherto unrecognized disease and play an important role in advancing medical science. For instance, HIV/AIDS was first recognized through a case report of disseminated Kaposi's sarcoma in a young homosexual man,[2] and a case series of such men with Pneumocystis carinii pneumonia.[3]
In other cases, description of a chance observation may open an entirely new line of investigation. Some examples include: fatal disseminated Bacillus Calmette–Guérin infection in a baby born to a mother taking infliximab for Crohn's disease suggesting that adminstration of infliximab may bring about reactivation of tuberculosis,[4] progressive multifocal leukoencephalopathy following natalizumab treatment – describing a new adverse effect of drugs that target cell adhesion molecule α4-integrin,[5] and demonstration of a tumor caused by invasive transformed cancer cells from a colonizing tapeworm in an HIV-infected person.[6]
Studies with a cross-sectional study design involve the collection of information on the presence or level of one or more variables of interest (health-related characteristic), whether exposure (e.g., a risk factor) or outcome (e.g., a disease) as they exist in a defined population at one particular time. If these data are analyzed only to determine the distribution of one or more variables, these are "descriptive." However, often, in a cross-sectional study, the investigator also assesses the relationship between the presence of an exposure and that of an outcome. Such cross-sectional studies are referred to as "analytical" and will be discussed in the next article in this series.
Cross-sectional studies can be thought of as providing a "snapshot" of the frequency and characteristics of a disease in a population at a particular point in time. These are very good for measuring the prevalence of a disease or of a risk factor in a population. Thus, these are very helpful in assessing the disease burden and healthcare needs.
Let us look at a study that was aimed to assess the prevalence of myopia among Indian children.[7] In this study, trained health workers visited schools in Delhi and tested visual acuity in all children studying in classes 1–9. Of the 9884 children screened, 1297 (13.1%) had myopia (defined as spherical refractive error of −0.50 diopters (D) or worse in either or both eyes), and the mean myopic error was −1.86 ± 1.4 D. Furthermore, overall, 322 (3.3%), 247 (2.5%) and 3 children had mild, moderate, and severe visual impairment, respectively. These parts of the study looked at the prevalence and degree of myopia or of visual impairment, and did not assess the relationship of one variable with another or test a causative hypothesis – these qualify as a descriptive cross-sectional study. These data would be helpful to a health planner to assess the need for a school eye health program, and to know the proportion of children in her jurisdiction who would need corrective glasses.
The authors did, subsequently in the paper, look at the relationship of myopia (an outcome) with children's age, gender, socioeconomic status, type of school, mother's education, etc. (each of which qualifies as an exposure). Those parts of the paper look at the relationship between different variables and thus qualify as having "analytical" cross-sectional design.
Sometimes, cross-sectional studies are repeated after a time interval in the same population (using the same subjects as were included in the initial study, or a fresh sample) to identify temporal trends in the occurrence of one or more variables, and to determine the incidence of a disease (i.e., number of new cases) or its natural history. Indeed, the investigators in the myopia study above visited the same children and reassessed them a year later. This separate follow-up study[8] showed that "new" myopia had developed in 3.4% of children (incidence rate), with a mean change of −1.09 ± 0.55 D. Among those with myopia at the time of the initial survey, 49.2% showed progression of myopia with a mean change of −0.27 ± 0.42 D.
Cross-sectional studies are usually simple to do and inexpensive. Furthermore, these usually do not pose much of a challenge from an ethics viewpoint.
However, this design does carry a risk of bias, i.e., the results of the study may not represent the true situation in the population. This could arise from either selection bias or measurement bias. The former relates to differences between the population and the sample studied. The myopia study included only those children who attended school, and the prevalence of myopia could have been different in those did not attend school (e.g., those with severe myopia may not be able to see the blackboard and hence may have been more likely to drop out of school). The measurement bias in this study would relate to the accuracy of measurement and the cutoff used. If the investigators had used a cutoff of −0.25 D (instead of −0.50 D) to define myopia, the prevalence would have been higher. Furthermore, if the measurements were not done accurately, some cases with myopia could have been missed, or vice versa, affecting the study results.
Ecological studies
Ecological (also sometimes called as correlational) study design involves looking for association between an exposure and an outcome across populations rather than in individuals. For instance, a study in the United States found a relation between household firearm ownership in various states and the firearm death rates during the period 2007–2010.[9] Thus, in this study, the unit of assessment was a state and not an individual.
These studies are convenient to do since the data have often already been collected and are available from a reliable source. This design is particularly useful when the differences in exposure between individuals within a group are much smaller than the differences in exposure between groups. For instance, the intake of particular food items is likely to vary less between people in a particular group but can vary widely across groups, for example, people living in different countries.
However, the ecological study design has some important limitations. First, an association between exposure and outcome at the group level may not be true at the individual level (a phenomenon also referred to as "ecological fallacy").[10] Second, the association may be related to a third factor which in turn is related to both the exposure and the outcome, the so-called "confounding". For instance, an ecological association between higher income level and greater cardiovascular mortality across countries may be related to a higher prevalence of obesity. Third, migration of people between regions with different exposure levels may also introduce an error. A fourth consideration may be the use of differing definitions for exposure, outcome or both in different populations.
Descriptive studies, irrespective of the subtype, are often very easy to conduct. For case reports, case series, and ecological studies, the data are already available. For cross-sectional studies, these can be easily collected (usually in one encounter). Thus, these study designs are often inexpensive, quick and do not need too much effort. Furthermore, these studies often do not face serious ethics scrutiny, except if the information sought to be collected is of confidential nature (e.g., sexual practices, substance use, etc.).
Descriptive studies are useful for estimating the burden of disease (e.g., prevalence or incidence) in a population. This information is useful for resource planning. For instance, information on prevalence of cataract in a city may help the government decide on the appropriate number of ophthalmologic facilities. Data from descriptive studies done in different populations or done at different times in the same population may help identify geographic variation and temporal change in the frequency of disease. This may help generate hypotheses regarding the cause of the disease, which can then be verified using another, more complex design.
As with other study designs, descriptive studies have their own pitfalls. Case reports and case-series refer to a solitary patient or to only a few cases, who may represent a chance occurrence. Hence, conclusions based on these run the risk of being non-representative, and hence unreliable. In cross-sectional studies, the validity of results is highly dependent on whether the study sample is well representative of the population proposed to be studied, and whether all the individual measurements were made using an accurate and identical tool, or not. If the information on a variable cannot be obtained accurately, for instance in a study where the participants are asked about socially unacceptable (e.g., promiscuity) or illegal (e.g., substance use) behavior, the results are unlikely to be reliable.

Q: How do you ensure accuracy when dealing with ints and doubles within conditions? Beginner here.
How does one ensure accuracy when dealing with small margins like this? one of my test cases results in 100.9 - which obviously isn't triggering the fee increase.
The floor division works for calculating the correct fee, but I'm not sure how to  handle that preceding statement. Do I need to type cast every number to a double?
        if ((Math.ceil(weightPerItemInOz * numberOfItems) / 16) > 100)
    fee = fee * (Math.floor((double)(weightPerItemInOz * numberOfItems) / 1000)); ```

Q: Fail to add/replace basicHttpBinding with wsDualHttpBinding I'm new in the WCF
I wrote some server that work on IIS 7.5
I using the basicHttpBinding endpoint - and i want replace or add support for the wsDualHttpBinding endpoint.
So i used the WCF configuration tool to change the basicHttpBinding to wsDualHttpBinding.
And nothing work.
I change back to http and add new endpoint that will define as wsDualHttpBinding - and nothing work.
( i change in the client also )
How can i support the wsDualHttpBinding ?
Why this is not working ?

A: After you change the endpoint on the server, you will have to change it on the client as well.
If you change to wsDualHttpBindingon the server, and do nothing to the client, it will remain as basicHttpBinding, and it will not work. The binding on the client will have to be compliant with the server binding for the communication to work between client and server.
If you have already tried this, please let us know which error message you get when trying to run your program.

Full Stack Dev / Product Mgmt / Testing
Software Engineer – Full-Stack (Campus) Full Time (Remote)
At 0x Labs, our mission is to create a tokenized world where all value can flow freely. We're a mission-driven and diverse team composed of world class talent from Coinbase, Google, Meta, Bitso, Citi, Spotify and other top companies. We are a remote-first and fully distributed company, with team members located across all of the continents besides Antarctica. As early pioneers in the space, we've made significant technical contributions to various Ethereum standards over the years; fun fact – our team helped establish the NFT token standard (ERC721).
In joining us, you'll take part in transforming the way that value is exchanged on a global scale. We're passionate about open-source software and decentralized technology's potential to act as an equalizing force in the world, and our technology is deployed by a wide array of projects at the forefront of internet and economic advancement.
Founded in 2017, 0x Labs created and now partakes in the development of 0x protocol: the open-source, global backbone for decentralized exchange. Alongside the core protocol, we also build and maintain products and service offerings including Matcha, the search engine for tokens, and 0x API, the endpoint for multi-chain aggregated liquidity. All of these offerings allow 0x Labs to continue marching towards our vision of building a tokenized world where all value can flow freely at the best prices and with the lowest transaction costs. This way, we can help businesses eliminate the complexity of accessing decentralized markets across all layers of the Web3 exchange stack and have more time to focus on what matters most: their product.
0x currently supports 8 major blockchains: Ethereum, Polygon, Fantom, Avalanche, Arbitrum, Optimism, BNB Chain, and Celo, and the 0x ecosystem has been rapidly expanding. With integrations across all of the top wallets and apps, including MetaMask, Coinbase Wallet and Coinbase NFT, Polygon Wallet, Brave, Matcha, dYdX, Zapper, Zerion, and Shapeshift, 0x is fast becoming the trusted standard for all decentralized exchange.
We're a remote-first company with core contributors in nearly ten countries and over twice as many cities. Our headquarters is in San Francisco, with an office available for anyone on the team to use at any time. We'll consider your application regardless of where you call home.
YOUR ROLE AS A FULL STACK ENGINEER
0x protocol is the exchange infrastructure for the internet. It is governed by the 0x DAO community which is, in large part, composed of ZRX token holders. Other stakeholders contribute and participate in the protocol public life: 0x integrators, market makers, blockchain analysts, analytics products, investors, and other 0x enthusiasts.
The current product suite that these audiences most commonly use includes Matcha, 0xTracker, ZRX Portal, and the institutional 0x.org website. In joining one of our applications teams, you'll own the end-user experience for these interfaces, giving 0x stakeholders the power to govern and benefit from the 0x open protocol.
Matcha is 0x Labs' first consumer-facing product. Built on top of 0x API, Matcha is a meticulously designed decentralized exchange that makes it safe and easy for anyone in the world to access crypto assets. We provide users with the best prices by aggregating liquidity from all of the major decentralized exchanges and splitting/routing orders intelligently. New features in the past year include limit orders, gasless trades, and dark mode.
0xTracker began as a community-driven effort and rapidly established itself as the most reliable source of truth for 0x network adoption and growth. Is it currently visited by thousands of users daily. We have aggressive goals to make it become the reference data tool for decentralized exchange data. It will become a cornerstone of 0x's go-to-market as well, as we believe that there's no better way to craft narratives than with data.
ZRX Portal launched in beta in early 2020 and serves as the hub for ZRX token holders, where community members can create and vote on protocol and treasury proposals. ZRX Portal currently attracts tens of thousands of 0x enthusiasts monthly.
We don't care much about your experience with our stack (or any specific stack); we care far more that someone has solid fundamentals, is generally intelligent, has strong learning agility, and is an overall upstanding human. We understand it takes time to ramp, and we're happy to invest with the right person if necessary.

If you're going to steal something, then steal something big.
You might as well be hanged for a sheep as for a lamb.
Back in 1969 a USAF sergeant stole a C130 from RAF Mildenhall in an attempt to fly it back to the US to be with his wife who was under considerable emotional distress.
Under the circumstances one can only have sympathy with the poor chap.
The aircraft eventually crashed in the English Channel about twenty miles north of the Cherbourg peninsula.
Rumours have circulated for years to the effect that it was shot down by either US or RAF aircraft although nothing has ever been proven.
Now a team of divers is hoping to find the aircraft and shed some more light on the affair.
RAF MILDENHALL, England — Almost 50 years ago Sgt. Paul Adams Meyer, a U.S. Air Force assistant crew chief, got drunk, impersonated an officer and stole a C-130 Hercules from RAF Mildenhall in England so he could fly home to his new wife. Two hours later he crashed into the English Channel.
Now a team of British divers called Deeper Dorset hopes to raise 6,000 pounds ($8,430) on an all-or-nothing Kickstarter to find the plane and uncover the truth behind the crash.
The divers have until April 11 to meet their fund-raising goal or go back to the drawing board.
What happened to Meyer has been subject to rumor and speculation for nearly half a century.
An Air Force investigation found that at least two U.S. F-100 Super Sabre fighter jets from RAF Lakenheath, a C-130 from Mildenhall and two RAF English Electric Lightning interceptors attempted contact with Meyers before he crashed into the English Channel near Alderney Island.
"Leave me alone for about five minutes, I've got trouble," Meyer said in his final transmission to his wife in a link-up over the sideband radio.
Members of Deeper Dorset believe they can locate the missing Hercules using existing research, sonar and photogrammetry, a technique that builds 3-D models of wreckage.
The diving team's previous successes include locating La Mahenge, an 8,000-ton cargo ship found 120 meters deep in the English Channel, and a British M1 submarine found 81 meters deep in waters off the port of Plymouth.
"I think this project is too interesting to just let it pass, and with the Kickstarter goal it can happen sooner and we'll be able to share more about what we find," Brown said.

Dubai seems to make more sense as a stopover than Singapore.
That's where NACA ducts came from, too.
Didja see what's going on there? How long did it take?
I notice that, while most jet engines have air intakes, this one appears to have an anger intake.
That plane is kinda like this birb.
So...Was there a fly over at Verne Troyer's funeral?


Amazon is selling the Apple iPod Nano 16GB (7th Gen) for a low £92.00 Free Delivery. This normally retails for £129. And we promise it doesn't bend.
About the size of a credit card — and just 5.4mm thin — the new iPod nano is the thinnest iPod ever made. It's the latest version of Apple's popular series, and comes with an upgraded, larger screen for music browsing.
Packing 16GB, the iPod Nano can hold up to 4,000 songs. It also comes with built-in FM radio.
But the iPod itself is not the only interesting thing about this music player. Apple designers and engineers had the goal of creating earbuds that rest and stay comfortably inside a variety of ear types — while also producing the best sound quality possible.
They tested 124 different prototypes on over 600 people. The result is a breakthrough for earbud headphones. They're called EarPods and Apple claims that the audio quality is so superior, they rival high-end headphones.
