The development of a Raytheon silicon transistor was initiated by Ivan Getting soon after he joined Raytheon in 1951. “There was a radio design section that contacted all of the radio manufacturers – Warwick, Emerson, Zenith, you name it. Speaking to the success of Texas Instruments in the market place Roger Webster, who worked on the Regency TR-1, strongly endorsed the advantage of being first to have its transistors in the first transistor portable and the credibility it gave his company. Raytheon was active with its own range of transistor receivers having introduced the FM101A, T100, T150 and T2500. In 1957 Texas picked up Bulova from Raytheon and Raytheon obtained Firestone. Texas stayed well ahead supplying Admiral, Columbia CBS, Halicrafters, Magnvox, Motorola, Sentinel and Westinghouse. General Electric had a similar customer count. Raytheon did better in 1956 and by the end of that year it was supplying Bulova, Dewald, Emerson and Hallicrafters. Both these manufacturers had RF transistors in late 1954 before Raytheon announced its entrants. This shows that Raytheon did not have a market leadership role: in 1955 the only third party suppliers were Texas Instruments and Sylvania. They were after me for transistors.” īy the end of 1955 the following transistor portables were on the market as shown in the table with their principal transistor supplier: Norman Krim confirms the problems of supplying RF transistors talking to Michael Woff: “Radio Shack was in Boston at the time, and they were able to get radios from Japan but they couldn't get transistors at all. The majority of Royal 500 sets were equipped with Sylvania transistors which they sold to manufacturers at a lower price than did Raytheon. “This expedient was necessary to enable us to produce sufficient quantities by using transistors from many sources” according to its service manual. For example, Zenith produced its Royal 500, a seven transistor pocket sized set launched in November 1955, with four chassis types to accommodate four different transistor line-ups: one supplied by Raytheon (CK760 & CK759)) two supplied by Sylvania (2N94 and 2N194 & 2N193) and one by Texas Instruments (2N145). Raytheon put little energy into promoting its RF transistors: this was because demand outstripped supply, a feature of the market in general. In order to promote the new portable to a public that had no exposure to transistors Raytheon gave away cards with a genuine dud transistor saying “Take this actual sample of an electronic miracle!” with an explanation of the benefits of transistors in the new set. The April '55 review of the Regency TR-1 found the $49.95 TR-1 to be a toy-like novelty which didn't come at a toy-like price, and stated that, "the consumer who has been waiting for transistor radios to appear would do well to await further developments before buying."The July '55 review of the Raytheon 8TP gave the set high marks: "The transistors in this set have not been used in an effort to build the smallest radio on the market, and good performance has not been sacrificed to attain this end." The 8TP series was ranked high in nearly all categories, "falling down only in sensitivity."” “The April and July 1955 issues of Consumer Reports separately put these two radios to the test, and concluded that Raytheon had every reason to call its 8TP the first serious transistor radio. Base width was controlled by monitoring electrical characteristics of the junctions as alloying proceeded. In 1956 George Freedman developed a method of controlling base width by starting with a wafer that included a PN junction and fusing an electrode containing a P impurity to an exposed N layer. (This geometry gives a stronger wafer than if the notches were cut parallel). Herman Nowak developed a method of obtaining alloy junction transistors with base width of only 1 mil by milling notches set at right angles on either side of the wafer and creating the base junction at the intersection of the notches. Raytheon research into improved RF performance focussed on methods to reliably reduce the base width of its transistors. Other than the above parameters, all the transistors in this range had identical specifications suggesting that they were made, tested and selected. The CK760 was adopted as a universal RF transistor and initially was used in all stages of the 8TP receiver in its first configuration. Notably the CK759 was not included in the initial release and may have been introduced later as a means of utilising low specification transistors that were usable as IF amplifiers.

After upgrading the app, make sure everything works before trying to switch to Hermes. See Upgrading to new React Native Versions for how to do this. If you have an existing app based on an earlier version of React Native, you will have to upgrade it first. This section explains how to enable Hermes on older versions of React Native.įirst, ensure you're using at least version 0.60.4 of React Native to enable Hermes on Android or 0.64 of React Native to enable Hermes on iOS. Hermes is the default engine as of React Native 0.70. For example, to breakpoint the next time some JavaScript is run, click on the pause button and trigger an action in your app which would cause JavaScript to execute.Įnabling Hermes on Older Versions of React Native If you don't see the "inspect" link, make sure the Metro server is running. You should now see a "Hermes React Native" target with an "inspect" link which can be used to bring up debugger. button to add the Metro server address (typically localhost:8081 as described above). Navigate to chrome://inspect in a Chrome browser instance. This is a tutorial about how to create run configuration inside JetBrains WebStorm (or PhpStorm) and debug javascript code inside IDE.JetBrains docs - https. Once you know where the Metro server is listening, you can connect with Chrome using the following steps: When running yarn start the address is written to stdout on startup. Typically this will be on localhost:8081, but this is configurable. Note that this is very different with the "Remote JS Debugging" from the In-App Dev Menu documented in the Debugging section, which actually runs the JS code on Chrome's V8 on your development machine (laptop or desktop).Ĭhrome connects to Hermes running on device via Metro, so you'll need to know where Metro is listening. If you've recently created a new app from scratch, you should see if Hermes is enabled in the welcome view:Ī HermesInternal global variable will be available in JavaScript that can be used to verify that Hermes is in use: You can read more about the technical implementation on this page. Learn more from the React Native official website. It is created by Facebook and used for such well-known apps as Instagram, Airbnb, and now JetBrains’ own YouTrack mobile application. You can still disable Hermes using the command described in this page. With React Native you can develop native mobile applications for iOS and Android using JavaScript and React. This change is fully transparent to users of React Native. This fully eliminates this problem, and offers users a JS engine that is compatible with the specific React Native version. Historically, we had problems with matching versions of Hermes with versions of React Native. This will make sure you're consuming a version of Hermes which is fully compatible with the version of React Native you're using. We will be building a version of Hermes for you whenever we release a new version of React Native. I assume you have some basic knowledge of React Native and I will be using : Mac, WebStorm IDE. WebStorm is an integrated development environment for JavaScript and related technologies made by JetBrains. React Native comes with a bundled version of Hermes. Here we are going to create a sample react native app and run it on a device with Expo Client. Hermes is used by default by React Native and no additional configuration is required to enable it. For many apps, using Hermes will result in improved start-up time, decreased memory usage, and smaller app size when compared to JavaScriptCore.

MapQuest allows you to choose up to 26 directions for each route. It is one of the best features for users on MQ. You don’t need to remember the exact place enter as much information as you know and MapQuest will bring the result to you in the fastest time. It helps users can easier to determine the needed time to move. The success of MapQuest comes from the reality of traffic moving on the road. MapQuest will get you there in a little time. Whatever the location you want to go to, the restaurant is attractive to you, but you don’t remember the hotel, the carport, the park. One of the new features of MapQuest Driving Directions is the box search. MapQuest Data helps make itself unique by guiding the user directly from the entrance of a position or beginning place to a destination, saving time on the road and while moving.Īllowing up to 26 points in each route is a plus because not all of the maps can now have a wide range of data and cover all the places in one route. MapQuest also concerns itself with the experience of customers by improving features such as nearby gas prices, the nearby bus stop, the fastest way, avoiding traffic jams, etc. It has a friendly home page and a useful website that can be accessed everywhere. MapQuest is currently a free mobile app, allowing download on Android or IOS with new features such as POI search, voice-guided navigation, and real-time traffic. Users also save the place, share, and print. MapQuest provides some detailed and expanded functions to determine location, detailed streets, and driving directions in your country. Now, the MapQuests mapping system uses TomTom's service. However, don’t worry about the MapQuest Driving Directions it is still effective and a new update for service online users with many functions that are flexible and useful. If static, the new network will be replaced immediately. The ups and downs of MQ from its beginning in 1966 to its conclusion in 2007 are evidence of strong competition in business and the run of technology. When comparing MapQuest with other similar mapping types, it’s not hard to realize MapQuest is unchanging and stable, while interesting new users like Google Maps or Apple Maps can be installed on smartphones and updated. In this case, AOL did not want to invest the time and money needed for MapQuest. The main reason for failure is the intense competition with Google and the pressure of investment from Google for Google Maps. According to an estimate, the company produces more than 1.5 billion printed maps per year, an amazing number of maps from 1967 to 2006.ĭespite being the first mover and becoming popular fast when released and supported by market leader AOL, MapQuest still went bankrupt and was undisclosed in 2007. MapQuest produced its first printed map in 1967 and distributed it for free at gas stations. MapQuest is like a Google Map that provides finding roads and locations. MapQuest is a mapping service that was launched in 1966 and became the first commercial web mapping service. With the advent of technology, we now have access to various tools and apps that can provide us with real-time directions, traffic updates, and alternate routes to help us navigate through unfamiliar areas. Mapquest Driving Directions and other Driving Directions services are definitely useful in modern times. That being said though, if i had access to the Revo in 12.4 as well as 12.9 I would have opted to try both before nailing my colours to one mast or the other. I liked my old wooden shaft, but compared with carbon fibre there is no contest imo and the Revo wins hands down!. Prior to switching to this, I previously played with an LD wooden shaft which was somewhere around the 12.4 - 12.6 mark. The main reason for me selecting the 12.9 in the first instance was primarily due to the fact that it was the only Revo shaft readily available at the time which i could try out. Thanks everyone for the replies so far guys. Any help, feedback, reviews or recommendations to enable me to make the correct choice here would be much appreciated. Hopefully the above kinda gives a general idea of the characteristics that I'm after as well as the concerns I have. Would someone who has experience playing with the 12.9 notice a big difference between that and the 12.4 or would it be relatively easy to adapt between the two?. Assuming that the 12.4 and 12.9 are similar, then just how similar are we talking here?. I guess what I really want to know is does the characteristics of the 12.4 air more towards the 12.9 than it does the 11.8 (taper, feel ect)?. The 12.9 would be the 'safe option' but if the 12.4 is easier to play with, more versatile and offers more benefits (such as potentially being easier to play table length draw with) then I would be seriously tempted by that shaft. Given that I was less than impressed with the 11.8 I have ruled that size out, so its a straight shoot-out between returning to a 12.9 shaft or giving the 12.4 a try. Its hard to explain why i didn't like the 11.8 but the feel upon tip/ball contact just felt weird somehow and I couldn't adapt to it sufficiently enough get any kind of consistently so my cue ball control suffered enormously!. I tried the 11.8 as I play a fair bit of snooker so a thin shaft isn't unfamiliar to me, but for whatever reason I really didn't like this shaft for playing pool with. The only ability which i occasionally lack with this shaft vs slightly smaller tip diameter wooden shafts is the ability to impart table length draw on the cue ball (This is partly why I have be contemplating switching to the 12.4 to see if it's easier to impart draw with that than it is the 12.9?). I started with a 12.9 and almost immediately I found that I really liked it. I have personally played with the 12.9 and 11.8 previously, but I have never tried 12.4 although I am tempted by the 12.4 due to it apparently being 'the easiest' and 'most versatile' of the three to play with. I'd also appreciate some feedback from those who have played with both shafts and could explain the differences (if any) in the way that they play and feel from your prospective. I am currently trying to decide between selecting a 12.4 or 12.9 revo shaft for my new pool cue and I was wondering if folk could help me figure out which would be the best choice for me. “It reflects that sense of togetherness, of male and female in an almost molecular and mechanical attraction, as well as a more classical sensuality-both feelings that I wanted to come across this season. “I wanted a feeling of attraction and sensuality in the collection, something sexual but not grotesque,” Kane told of the designs inspired by figure drawings made by his studio. It’s a scary thing, isn’t it?” A week later in London, Christopher Kane put said private parts, as well as other parts of the female and male anatomy, on display in a series of guipure lace dresses showing intertwined nude figures. Tyra Banks appeared on the catwalk wearing a relaxed suit and a sheer mesh top, accessorized with a coordinating beret and a belt bag. The subject of nudity started trending on the very first day of the fall collections at the Rachel Comey show with a performance by Tracee Ellis Ross as Madame Hiver, a life coach whose proclamations included, “Your vagina wants to sing!” and “It’s just a vagina. “I think with all the minimalism and androgyny fashion has experienced in the past seasons, designers are exploring more the sexuality of women and expressing the beauty of the human form,” mused MyTheresa’s Justin O’Shea on the abundance of T-and-A in New York, London, Milan, and Paris. In fashion, the topic has manifested in a myriad of ways, from Chanel’s spring 2015 protest march-cum-runway show to an abundance of “Free the Nipple”-type nudity on the fall 2015 catwalks. Case in point: Kim Kardashian stepping out in tops that are so plunging her breasts are fully exposed Rihanna wearing a totally sheer. Feminism has been a hot-button issue in pop culture lately-whether through the lens of a TV show like Girlsor a moment such as ** Beyoncé’**s VMA appearance, when she performed with the word feminist spelled out in bold letters behind her.

Most of the ocean is not visible from the surface. Your challenge is to invent a method to explore the deep ocean and discover the fantastic organisms hiding there. Because they are so inaccessible, researchers use special sensors or remotely operated vehicles (ROVs) to explore these habitats instead. That means researchers have a lot of work ahead of them! But it isn’t easy to explore the deep ocean -the pressure is 100 times that on land, temperatures are near freezing, and the complete darkness makes it impossible for people to explore on their own. Scientists estimate that less than 10% of ocean species have been discovered as of today. Over 80% of the world’s oceans are unmapped, unobserved, and unexplored. However, many species in the deepest parts of the ocean are at risk of extinction due to climate change and pollution. These strange and wonderful deep-sea organisms have the potential to reveal new medicines, vaccines, foods, energy sources, minerals, and more. They inhabit a world unlike any other on Earth and are adapted to survive in extreme conditions. Deep in the darkest, coldest regions of the ocean live some of this planet’s most unique creatures.
