I have questions, using mmap for such a system, 1. Do you mmap the whole file into the address space or mmap the database file one page at a time as requested my the access method (a b+tree here)? If the former is the case then I believe, we can not have more than 4GB database on 32 bit systems. 2. What happens when a new page is allocated and the database file expands, if you remap the (assuming you map the whole file) file then all the pointers to the file are now invalid, requiring you to restart the operation. How is this done? I need these answers for a personal project.

Why Doesn’t it have Support for Perl?

Great talk. Hope you are doing fsharp content even this long afterwards. =)

merci internet, grace a cette video QUI DATE DE 2014 je vais pouvoir réaliser mon sujet de grand oral. un grand merci a vous

This is really a great talk but I would love to be able to see the live programming window!

Thank you. So many things I learned in a hour!

mais mais, l url est toujours dispo, on a pas de liens?

Do a couple of projects at the same time you review this video to connect ideas. A lot is going on with Dagger that is important to make as many projects as time allows. Great talk.

 Donner moi un cas pratique pour : Créer une application Big data d'enregistrement de naissance ou de gestion de pharmacie avec ces langages et technologies suivant : JavaScript, HTML,CSS,apache,tomcat,oracle,SQL serveur,mongoDB, postgre sql, hadoop, cloud databases, blockchain databases

🤦‍♂

Great! All true

Might be the worst presentation ive ever seen lol

Can you please Help Me With This CAR please and thank you So Daddy Jesus Christ Can Stop Crying 😭😭😭 he's Sad

The author mentions that LMDB does a lot of IO for writes but since this is append only, its first. But given that it uses free pages first for doing IO, if avilable, wouldnt that lead to randomized IO. Even with mmap, I guess a production system would msync per transaction, so this would slow it down signifcantly?

Great lecture. One of the best out there....But empaths could get stressed out..

Don't believe the comments below. This talk is all over the place and not easy to follow. The descriptions are too abstract and obfuscated. I would be quite discouraged as a beginner to Scala after watching this.

At 33:45 I don't agree with the approach he suggested to use a drawable which uses hardcoded height like the android:bottom="48dp" on the item element. What if the height of the button changes? I think a better approach is to still use the ImageView, remove the LinearLayout and instead of the parent FrameLayout use ConstraintLayout. Using the Drawable like that it's a nice hack, but it's still a hack.

I dont undertand why they put such a bad picture on the left. 😐

great

Rest in peace Bob 🙏🏼 a man ahead of your time who lived life to the fullest. Condolences to your family 🙏🏼

What a shame to lose this smart, logical, thoughtful software engineer to an unhinged killer that lied about being a Berkeley graduate. How does that compute? A fraud, liar, murderer.

Impeccable presentation about a very interesting subject: Software craftsmanship. Thank you Sir! just for fun, didn't know Joey Trebbiani is a Software engineer :)

just by looking at the thumbnail, I agree 100% and how much we failed just because Alan Kay decided to implement the very first version imitating Simula.

28:08 it would actually, fields are initialized first. hope he knows it today

Great talk!

Good presentation, thanks

This is awesome!!!! The tech community should jump on this

Merci pour cette vidéo c'est très bien synthétisé. Je n'ai pas bien compris l'exemple 3 à 00:41:43. D'où vient le "function" en second paramètre de thenCombine ? cet exemple n'est pas très clair. J'aime bien Java mais malheureusement il est en perte de vitesse pour les IHM. Java FX est très mal documenté, j'étais habitué à Swing et je regrette cette époque. Je travaille en l'asynchrone avec les Promisse de Javascript (je n'aime pas JavaScript) et l'API Java8 y ressemble beaucoup. Je n'aime pas vraiment les expression lamba : bien utilisées, elle rendent le code lisible justement dans le cas des chainages de fonction (en évitant les "new", les parenthèses, les closures, certaines déclarations de variables locales temporaires) mais malheureusement beaucoup en abusent dans d'autres cas et ça rend illisible la lecture de code d'exemples qu'on peut trouver sur le net.

Apres avoir implémenté le "afterTest", il ne faut pas virer le "clear()" ds le 1er test ?

I am a bit confused when researching - the SecurityManager is deprecated, and yet the OCAJP IZO-819 exam has questions centric to granting permissions via the policy file

Great talk.. Thank you

un lien sur l'article "the most dangerous code" ?

Thanks for the explanation you made it pretty simple in video

Hey bro! I need soone who know After effects. Can you help?

You should be my maths teacher

Guys my GMS softs like a dead rat! How can i change it to the one that he has?

je serai curieux de savoir comment sont scorées les vraies grilles de sorties lors des tirages réelles ? chaque mardi et vendredi soir puis scorées les grilles par exemple des gagnants de la super cagnottes ???

c'est quoi l'intérêt de faire du java au lieu de ruby sur puppet? j'ai vu un type qui faisait tourner çà avec du java, pourquoi je sais pas es ce que c'est mieux je sais pas non plus...

can i pls get his code ?

this video is great. Thanks!

j'ai vraiment aimé cette vidéo et j'aimerais avoir plus d'explication sur influxdb

Amazing presentation

Merci pour cette présentation qui a été si enrichissante.

Aren't sum types EXCLUSIVE ors?
