Capacity Provisioning for Server Farms

由 浪子不回头ぞ 提交于 2020-01-16 17:07:52
问题 Suppose I have N M/M/1 queues in parallel where an arriving job is equally likely to join one of the N queues. We want to keep the probability for a job to wait less than 0.2. Given that we have an arrival rate of 400 jobs/second, and a processing times are exponentially distributed with mean 1 second, how many servers would be required? So my take on the question so far is: \lambda = 400 jobs/second \mu = 1 second \rho = (\lambda)/(k\mu) since we want to keep the probability of waiting less

How do I add another developer's certificate to the iOS provisioning portal?

由 帅比萌擦擦* 提交于 2020-01-12 07:06:13
问题 I've been trying to enable another developer on my team to build an iPad app that we are creating for a client, but am having no luck getting his development certificate uploading into the provisioning portal. I'm starting to think I'm missing something simple. My assumption is that each developer needs to have their own certificate listed on the Certificates -> Development page. Is that right, or are we supposed to be using only one certificate? We tried setting him up with the certificate

浅谈分布式存储之SSD基本原理

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 前言 随着制造工艺的不断进步，SSD(Solid State Drive)性能和容量不断突破，价格不断降低，迎来了快速的发展，目前已经是商用服务器、高性能存储服务中非常流行的存储介质。作为开发人员，需要了解SSD的基本原理，以便开发时能更好地发挥其优势，规避其劣势。本文章基于末尾所列参考文献整理而来。 目录 SSD简介 闪存基础 存储原理 读写流程 GC机制 Trim机制 Bit-Error Read-Disturb Program-Disturb Wear-Leveling IO抖动因素 SSD简介 SSD诞生于上世纪70年代，最早的SSD使用RAM作为存储介质，但是RAM掉电后数据就会丢失，同时价格也特别贵。后来出现了基于闪存(Flash)的SSD，Flash掉电后数据不会丢失，因此Flash-SSD慢慢取代了RAM-SSD，但是此时HDD已经占据了大部分的市场。到本世纪初，随着制造工艺的不断进步，SDD迎来了长足的发展，同时HDD在工艺和技术上已经很难有突破性的进展，SSD在性能和容量上还在不断突破，相信在不久的将来，SSD在在线存储领域会取代HDD，成为软件定义存储(SDS)的主流设备。 闪存基础 SSD主要由SSD控制器，Flash存储阵列，板上DRAM(可选)以及跟HOST接口(SATA、SAS

Developing for iOS on multiple computers, testing on a single device, advice?

由 微笑、不失礼 提交于 2020-01-10 06:17:06
问题 I was looking for some advice on provisioning profiles / certificates etc... I use an iMac at work to develop on, and I also sometimes find myself checking out my code from git onto my MacBook Pro at home but I always run into issues when I want to test on my iPhone from another computer. Obviously my provisioning profiles on the device match the certificate issued to my iMac from work, so from my laptop, I can't test on the device because the provisioning profile doesn't match a certificate.

Why I can't add APNs Development iOS typed certificate to provisioning profile

由 女生的网名这么多〃 提交于 2020-01-01 06:49:06
问题 I am trying to implement APNS for my App. I created APP id and was able to generate an SSL certificate for my App (the type is shown to be APNs development IOS). However, when I try to generate a provisioning profile, following the screen where I choose the AppID of my app, I do not see the SSL certificate I generate for this app. In the certificates list, I only see certificates of type 'IOS development' that were created previously. 回答1: The APNs certificate that you created is used by what

Provisioning Profiles Can Be Installed Using MDM

由 杀马特。学长 韩版系。学妹 提交于 2020-01-01 05:42:06
问题 Apple's Mobile Device Management Protocol Reference states on page 44 at the bottom Third-party enterprise applications require provisioning profiles in order to run them. You can use MDM to deliver up-to-date versions of these profiles so that users do not have to manually install these profiles, replace profiles as they expire, and so on. To do this, deliver the provisioning profiles through MDM instead of distributing them through your corporate web portal or bundled with the application.

Set Expiration of Provisioning Profile

由 六眼飞鱼酱① 提交于 2019-12-31 01:51:47
问题 Is it possible to set the expiration date of a Provisioning Profile? I am having an internal trial within the company and I would like to set the expiration date to be the end of the trial; instead of just being a year from the creation date. Is it possible or is it always going to be one year from the creation date? Also, if its not possible to set the expiration date, is it possible to kill the provisioning profile from the portal that way the application itself will expire and not be able

Pass command line argument to vagrant shell script provisioner

问题 Similar to this question: Passing variable to a shell script provisioner in vagrant I want to pass variables to a shell script provisioner but I want to set these variables on the command line when I call the provisioner. Is this possible? 回答1: This is what I would try - I guess there are possibilities as Vagrantfile is a ruby script, you can use most of ruby possibilities Be careful though as vagrant might need to check for variables, for example when doing vagrant up arg1 arg2 , it expects
