مهندس يبتكر تصميم فندق طائر يعمل بالطاقة النووية، يسع لـ5 آلاف راكب ويستطيع البقاء في السماء لسنوات!

#شاب يمني يصمم فندقاً طائراً يعمل بالطاقة النووية ويبقى في الهواء إلى الأبد
كشف مصمم يمني عن تصميم لفندق طائر يعمـل بالطاقة النووية وبمقدوره استيعاب 5 آلاف شخص، ويضم العديد من المرافق الأساسية والترفيهية.
 
حيث أصبح الخيال العلمي شبه واقعي بفضل المصمم العربي هاشم الغيلي، فقد ظهر فيديو على الإنترنت في شكل مفهوم طائرة فندقية يمكن أن تحمل 5000 راكباً ولن تحتاج أبداً إلى الهبوط لعدة سنوات ولا حتى ستحتاج للوقود.
الفندق الطائر تمت تسميته باسم فندق سكاي كروز – Sky Cruise، وهو فندق طيران عملاق مستقبلي يعمل بالطاقة النووية.
ويملك وسائل الراحة الأساسية مثل صالة الألعاب الرياضية وحوض السباحة مع القدرة على نقل حوالي 5000 راكب.
و تم تصميم “سكاي كروز” مدعوما بالذكاء الاصطناعي.
 
والذي يحتوي على 20 محرك مدعوم بالاندماج النووي، بحيث لا يهبط على الأرض أبداً ويظل يحلق في السماء.
أما عن كيفية وصول النزلاء للفندق الطائر فسيتم نقل الركاب من خلال الطائرات التقليدية من وإلى Sky Cruise وحتى جميع الإصلاحات الجارية سيتم تنفيذها على متن الطائرة وهي محلقة
ونقلت صحيفة “نيويورك بوست” الأميركية عن هشام الغيلي قوله: “ستمثل الرحلات على مركبات تعمل بالطاقة النووية مستقبل النقل والسفر”.
 
ووفق “غيلي“ فإن الطائرة ستحتاج لطيارين بداية، ولكنها قد تستغني عنهم في المراحل اللاحقة.
لكن “سكاي كروز” ستظل تتطلب الكثير من الموظفين من أجل خدمة نزلاء الفندق الطائر الفاخر
ويحوي الفندق أيضا مطاعم ومركز تسوق عملاق في السماء، بالإضافة إلى صالات رياضية ومسارح وحتى حمام سباحة.
وتم اقتراح آلة الطيران العملاقة (الفندق الطائر ) أيضاً كمكان مثالي لإقامة حفلات الزفاف.
ومع ذلك، لا يتفق الجميع مع بعض المعلقين الذين وصفوا مفهوم سكاي كروز بأنه تيتانيك الجديد.
مشيرين إلى أن وجود مصاعد على السطح الخارجي للطائرة سيكون بعيداً عن الديناميكية الهوائية وأنه إذا تحطمت طائرة تعمل بواسطة مفاعل نووي، يمكن أن تدمر مدينة.
 
حيث قال أحد المعلقين: “فكرة رائعة وضع مفاعل نووي في شيء يمكن أن يتعطل ويسقط من السماء.”

أفـضـل إضـافـات VS Code

أصبح محرر الأكواد VS Code من أشهر المحررات استخداماً بين المطورين، فهو محرر مجاني ومتعدد المنصات قامت بتطويره شركة Microsoft.
 

إليكم بعض أفضل الإضافات التي بإمكانك إضافتها لمحرر الأكواد هذا:

1. إضافة : Settings Sync
يُعد Settings Sync واحدًا من أفضل البرامج التي يجب أن يمتلكها كل مستخدم ويجب أن يكون له امتداد VS Code. السبب في ذلك هو أن Settings Sync ستقوم بمزامنة جميع إعدادات VS Code الخاصة بك، وربط المفاتيح، والقوالب، وقائمة اللواحق مع GitHub. هذا يُلغي الحاجة إلى إعادة تثبيت كافة الملحقات والثيمات وإعادة تكوينها في كل مرة تقوم فيها بتثبيت VS Code أو عند استخدام VS Code على أنظمة متعددة.
 
أفضل شيء عن Settings Sync هو أنه من السهل جدا للاستخدام. في الواقع، بعد ربطه بـ GitHub، يمكنك تحميل أو مزامنة الإعدادات باستخدام اختصار لوحة مفاتيح واحد فقط. إذا لزم الأمر، يمكنك تهيئته لتحميل أو تنزيل الإعدادات تلقائيًا.
2. إضافة : Live Server
إذا كنت من مطوري الويب أو مجرد شخص يعمل مع تقنيات الويب مثل CSS، و JavaScript، و PHP، و HTML، وما إلى ذلك، فستكون خدمة Live Server ضرورية بالنسبة لك.
 
ما يفعله Live Server هو أنه سيقوم بإنشاء خادم محلي داخل VS Code ويتيح لك فتح صفحات التطوير بنقرتين فقط في أي متصفح من اختيارك. لا حاجة للذهاب يدويا إلى موقع الملف وفتحه من هناك. ناهيك، عندما يكون Live Server نشطاً وعاملاً، ستتم إعادة تحميل الصفحة تلقائياً في كل مرة تقوم فيها بحفظ المستند. لذلك، إذا كنت من مطوري الويب، فأنصحك أن تجرّبها.
 
3. Open in Browser
كما يمكنك أن تعرف من الاسم نفسه، يسمح لك إضافة Open in Browser بفتح أي ملفات مدعومة في المتصفح الافتراضي أو في المتصفح الذي تختاره بنقرة واحدة. على الرغم من أنها ليست قوية أو غنية كامتداد Live Server، إلا أن Open in Browser يساعدك على معاينة مستند الويب بسرعة دون إنشاء مثيل للخادم في الخلفية. كما أنه خفيف الحجم إلى حد ما ويفعل ما ستفعله دون حدوث أي خلل.
 
4. Prettier
كما يوحي الاسم، يجعل Prettier الشفرة تبدو جميلة ويحسن إمكانية القراءة عن طريق تنسيقها بشكل صحيح وفقاً للمعايير الرسمية ومعايير الصناعة. بعد تثبيت الإضافة، يمكنك إمّا تهيئة الرمز الخاص بك عن طريق الضغط على اختصار لوحة المفاتيح أو تهيئة
 

 

Did you know New Data shows for the month of April, Google Chrome is the only web browser that hasn’t observed a major drop in its market share

Mozilla Firefox used be our go-to web browser for a really long time. It was released in September of 2002 and people who used the internet went to this web browser for their daily surfing. Google released its own web browser called the Google Chrome in 2008, and since then there has been no looking back for this browser as the success it was able to achieve in a really short amount of time is something which hasn’t yet been observed from any other browser. Microsoft released its web browser called Microsoft Edge in 2015 for Windows 10, in 2017 for Android and IOS devices and for macOS in 2019. Then finally it was released as a preview for Linux in October of 2020.

If there is any browser that was able to compete up to Google Chrome, then it has to be Microsoft Edge. Mozilla Firefox lost its thunder soon as Google Chrome started to rise, even though Firefox was used by many users worldwide, the web browser wasn’t able to come to Google Chromes level. Microsoft Edge too started off with a bang giving a tough competition to Google Chrome, but according to recent reports, Microsoft Edge and Mozilla Firefox are losing their market share, and Google Chrome is apparently having a major increase in its market shares. Google Chrome has never for once taken a break, the browser has always come up with new and innovative features that attracts majority of the users online. Hence the ever increasing results always.

StatCounter published the market share data for the month of April of this year. According to the data it can be seen that Google Chrome is a browser that hasn’t dropped a single percent in its market share, the web browser had around 67.55 percent of desktop browser market share, an increase from 67.14 percent which the browser observed in March 2021. Edge saw decrease with 8.03 percent in March, the market share dropped to 7.96 percent in April, and Firefox went from 7.95 percent in March to 7.78 percent. Safari which is the web browser made specifically for macOS, dropped from 10.11 percent in March to 9.85 percent in April.

Safari remains the second most used browser followed by Microsoft Edge as the third most used browser. The data shows how much Google Chrome represents the market share and this speaks high volumes as to the user experience which Google Chrome is able to bring for its users.

Did you know Twitter is rolling out its new “Tip Jar” feature that will allow users to donate to their favorite influencers, but for now only a few accounts are able to receive money

Twitter is one of the biggest micro-blogging platforms in the world where many users can also run their business, learn something, and create content for others. This could be great news for the content creators that Twitter has officially introduced the next stage of its creator’s payment program in the form of a new feature “Tip Jar” in which users will be able to send money or donate to their favorite influencers as a mean to support their efforts that they put in while making the content. However, only a few accounts are able yet to receive the money from the users, but the users who are using this platform in the English language can now send their funds to their favorite accounts.

Twitter decided to test this feature in favor of creators because they were linking their PayPal accounts and adding $Cashtags and Venmo handles with their profile so that people support them financially. The idea is beyond just becoming a follower or tweeting or liking their accounts. Other platforms like YouTube have also this feature in which the subscribers can donate the creators through Super Chat while they are live streaming, and this is the best idea to support their work. Many youngsters are getting inspiration to create their own content, especially during the quarantine situation.

This feature will be rolled out on mobile apps of Android and iOS devices and this will be easy to use. In the beginning, only a selected group including creators, journalists, and non-profits can turn on the Tip Jar feature to accept the donations from the users. To turn this feature on, you can go to the option of Edit Profile on Twitter for iOS and Android app, then click the Tip Jar feature, and then go to the setting, tap on the allow tips on and then select the third-party service that you would like to get. But one thing you must keep in mind that when you try to add a third-party payment service to your profile, your username on that service will be publicly connected to the account of Twitter.

There are some issues that are highlighted by Rachel Tobac that sending funds through PayPal using the feature of Tip jar currently permits whoever is sending the money to see the recipient’s address, which is fretting security issue that PayPal and Twitter will solve soon. The support center of Twitter accepted the issue and tweeted that it was updating our tipping prompt and Help center to make it transparent that other apps may share information between people sending or receiving the funds are as per the terms.

Apart from this, YouTube has also announced some new tools in its Shorts feature which will be launching really soon. These include the ability to record for 60 seconds though there are speculations that if you record a video with music from the YouTube library the recording will be capped at 15 seconds, though how true is this will only be confirmed once this feature is launched. Apart from this, color-correcting filters that will live both within the recording and editing screens; and auto-generated or self-supplied, manual captions are also being launched.

The company in order to make Shorts more discoverable and easy to be accessed by the users is also bringing along changes in the mobile app of YT where a new “Shorts” tab will be added at the bottom of its mobile home screen alongside ‘Home’, the create button, ‘Subscriptions’, and ‘Library’ as well as Shorts will replace the ‘Explore’ tab, YouTube says, which will now appear as the first bubbled topic at the top of the home feed.

Shorts have proven to be a great feature for YouTube and the company has a lot of expectations from it. We cannot wait to see when the tech giant will launch this feature globally.
