Microsoft SQL Server Express Edition (SQL Server Express) supports the user instance feature, which is only available when using the .NET Framework Data Provider for SQL Server (SqlClient). A user instance is a separate instance of the SQL Server Express Database Engine that is generated by a parent instance. User instances allow users who are not administrators on their local computers to attach and connect to SQL Server Express databases. Each instance runs under the security context of the individual user, on a one-instance-per-user basis.
User Instance Capabilities
User instances are useful for users who are running Windows under a least-privilege user account (LUA). Each user has SQL Server system administrator (sysadmin) privileges over the instance running on their computer without needing to run as a Windows administrator as well. Software executing on a user instance with limited permissions cannot make system-wide changes because the instance of SQL Server Express is running under the non-administrator Windows account of the user, not as a service. Each user instance is isolated from its parent instance and from any other user instances running on the same computer. Databases running on a user instance are opened in single-user mode only, and it is not possible for multiple users to connect to databases running on a user instance. Replication and distributed queries are also disabled for user instances.
Enabling User Instances
To generate user instances, a parent instance of SQL Server Express must be running. User instances are enabled by default when SQL Server Express is installed, and they can be explicitly enabled or disabled by a system administrator executing the sp_configure system stored procedure on the parent instance.
SQL
-- Enable user instances.
sp_configure 'user instances enabled','1'
-- Disable user instances.
sp_configure 'user instances enabled','0'
The network protocol for user instances must be local Named Pipes. A user instance cannot be started on a remote instance of SQL Server, and SQL Server logins are not allowed.
There are so many things to remember to bring with you on a Whistler skiing trip; therefore, here is a reminder of some of the items you will need.
Hat – perfect to hide your hat hair for apres-ski activities. My favourite hats are from Roots – purchase your Roots hat here
Thermals – bring plenty of layering options to regulate your perfect temperature. My thermals are from Mountain Warehouse.
Backpack – use it as your plane carry-on and then repurpose it as your day bag while skiing. You will need plenty of things during the day, such as your hat, extra layers, water, snacks etc. My backpack is from The North Face or consider this Osprey backpack
Snow pants – this is one of the most essential items to bring for Whistler skiing or snowboarding. I recently bought snow pants from Helly Hansen and I love them.
Ski coat – again, another obvious, must-have item. If you want to fit in with the crowd at Whistler, bring an Arcteryx ski coat – you will see so many people wearing them. There is also an Arcteryx outlet store in North Vancouver.
Blundstone boots – these are one of my favourite winter clothing items in winter. Blundstones work well for après ski and travelling. Buy Blundstones here
Swimwear – many accommodations have hot tubs, so do not miss out on the fun by forgetting your swimwear.
Spare jacket – it is not necessarily an essential item, but nice to have. You may want to bring a second coat to travel in and wear around Vancouver. I brought my North Face raincoat because it was raining in Vancouver in winter.
Ski or snowboard equipment – if you are bringing it with you, make sure you have a helmet, skis, poles, ski boots or whatever equipment is relevant for you.
Multi-tenancy is an architecture in which a single instance of a software application serves multiple customers. Each customer is called a tenant. Tenants can be given the ability to customize some parts of the application, such as the color of the user interface or business rules, but they can't customize the application's code.
In a multi-tenant architecture, multiple instances of an application operate in a shared environment. This architecture is able to work because each tenant is integrated physically but is logically separated. This means that a single instance of the software will run on one server and then serve multiple tenants. In this way, a software application in a multi-tenant architecture can share a dedicated instance of configurations, data, user management and other properties.
Multi-tenancy applications can share the same users, displays, rules and database schemas. Users can customize the rules to an extent and the database schemas.
Importance of multi-tenancy
Multi-tenancy is an old idea and traces its roots to classical mainframe architectures where many apps and users shared a common computing hardware platform. With the reintroduction and broad adoption of modern hardware-assisted virtualization, the ability to share hardware among multiple software instances -- such as virtual machines (VMs) and their applications -- placed a new emphasis on multi-tenancy capabilities. The technique gained popularity across local data centers and within hosted infrastructures normally associated with colocation and other shared IT services -- all enabling many users to share limited or common hardware infrastructure.
A database is crucial in the development of a software, which helps to store and retrieve data while working with an application. One of the most widely used databases is Microsoft SQL Server. Microsoft has released many variants of its SQL Databases that cater to the requirements of different users. However, the major question is that how will users decide which SQL environment is perfect for them? In this blog, we will outline the differences between SQL Server, SQL Express and SQL Azure. If their features can be understood distinctly, users will be able to make an informed decision about which software to opt for.
Introduction
Each software needs a database which will be best suited for it. A number of SQL supported databases are available for use. Users prefer to use Microsoft SQL database management systems because they are robust, and reliable. The most commonly used MS DBMS are SQL Server, SQL Express and SQL Azure. MS SQL Server primarily stores and retrieves data from a database. It has different versions, like Enterprise, Standard, Web, etc., that support varying workloads.
SQL Server Express, on the other hand, is a free database management system, which is a subset of SQL Server. It works well with small-scale or embedded applications.
The latest offering, SQL Azure is the cloud database for app developers. It is encrypted, scalable, and more productive. It comes with smart analytics, can recognize patterns, and adapted features for increased reliability.
Further differences between SQL Server, SQL Express, and SQL Azure are enlisted in the following section.

No matter which version of Windows you’re using, this article gives you a complete and step-by-step guideline on how to install IIS on Windows 10 and other platforms such as Windows server 2019, 2012, and 2012.
Microsoft has hit the tech market with its excellent IIS service, which has topped all the rivals and been the most popular web server for Windows. You can make sure of your web application and website’s high performance after installing IIS on your Windows server. As the name gives us a hint, IIS works best on Windows OS. However, you could use it on other platforms like Linux, but it won’t give you reliable performance.
What is IIS?
Internet Information Services (IIS) is a flexible and standard web server from Microsoft that runs on Windows systems to serve the requested pages or HTML files. The IIS server runs on the Microsoft .NET platform on Windows OS.
The IIS server receives requests from remote computers and, in return, responds with the correct response. That allows web servers to share and transmit data to all local and online networks.
Information sent to users is displayed in many ways, such as static web pages, through file exchanges such as downloads and uploads, and text, images, and more.
How Does IIS Work?
IIS operates with the help of standard protocols and programming languages. For things like text, buttons, image insertion, direct link/character, and hyperlinks, IIS uses HTML. HTTP is used to exchange information between a web server and a user.
HTTPS – HTTP over Secure Sockets Layer (SSL) uses Transport Layer Security or SSL to encrypt additional data security communications. File Transfer Protocol (FTP), or its secure alternative, FTPS, can transfer files. Additional supported agreements include Simple Mail Transfer Protocol (SMTP), sending and receiving email. The processes mentioned above and other languages and conventions together form an appropriate IIS package.
Fundamental analysis evaluates securities by attempting to measure their intrinsic value. Technical analysis differs from fundamental analysis, in that traders look to statistical trends in the stock's price and volume. Both methods are used for researching and forecasting future trends in stock prices.
I should get back into SABR position with three good chances from Nov. 29, 2021 to Jan. 13, 2022. I like to write down and think about more carefully later.
From Nov. 29 - Dec. 29, 2021
1. Buy low and sell high, I sold $5.87/ share 6000 shares, and I had chance to get back in $5.5/ share
2. SABR went up $6.8 in short time and then swinged down
3. SABR went down $5.5 again the second time - Do not aim too high, if I can save $1800 us dollars, but I Got 6000 shares back, and then invest $1800 on NCLH stock, it is a good deal
3. I had chance to get back in at $6.10 when it had loss over 11%, and then it rebounded $6.5, and then rebounded $6.8
4. Overall, it is in a bear market; I should not waste the opportunity of rally.

The new Elizabeth Holmes? Forbes 30-Under-30 winner duped JP Morgan into buying 'Amazon for higher education' startup for $175 million by making up millions of fake users to bolster credibility, lawsuit claims
Charlie Javice, 30, allegedly created false customers to complete the sale
JPMorgan bought the entrepreneur's education start up for $175M in 2021
The bank alleges she fabricated data for four million fake student customers
Javice is being sued by JPMorgan, who she claims is trying to 'retrade the deal'
A 30 year-old entrepreneur is being sued by JPMorgan, which claims it was misled into buying her education startup for $175million.
JPMorgan Chase says that Charlie Javice created four million fake users to increase the credibility of her fintech company Frank when she sold it to the bank in 2021.
Javice started the company in 2019 at 24 and was listed on the Forbes 30-under-30 list in 2019.
Frank offers software to improve the student loan application process for Americans seeking financial aid and it was once branded 'the Amazon of higher education.'
Javice and another executive at the company, Olivier Amar, allegedly paid a data scientist $18,000 to create a list of fake customers when its own employee refused, the lawsuit alleges.
Javice, who is the daughter of a successful investment manager based in New York, purchased an apartment in Miami Beach in May 2021 for just under $1.5million, according to Miami-Dade property records.
She started Frank a few years after graduating from Wharton business school, she revealed during an interview about her entrepreneurial success with a former tutor, which the school uploaded to its YouTube channel.
In the lawsuit, filed in a US District Court in Delaware last year, JPMorgan said that it was pitched the company by Javice on a 'lie' that more than four million users had signed up to use the tool.
After the bank asked for proof of that claim while carrying out due diligence, she and Amar allegedly fabricated a database of names, addresses, schools and dates of birth for fictitious students.
The data suggested Frank had around 4,265,000 customer accounts - in reality fewer than 300,000 of those were legitimate, it's claimed. The bank says the scheme unraveled when it tried to email those users and 70 percent of its emails bounced back, the Wall Street Journal reported.
Javice made $10million as part of the merger with JPMorgan, with a $20million bonus to follow at a later date. Amar made $5million from the deal, with a similar $3million bonus, Forbes reported. Both joined JPMorgan after the acquisition, according to their LinkedIn profiles.
The court filing includes alleged email exchanges between the hired data scientist and Javice in which they explain the methodology behind the fraud.
'Our plan was to sample first name and last name independently and then ensure none of the sampled names are real,' the lawsuit alleges they said to her.
The lawsuit also accuses Javice of initially trying to dodge the bank's request for that customer information. 'Javice first pushed back on JPMC's request, arguing that she could not share her customer list due to privacy concerns,' it said.
'After JPMC insisted, Javice chose to invent several million Frank customer accounts out of whole cloth,' it added. Included in the complaint were screenshots of presentations Javice gave to the bank making the false claims about its number of users.
JPMorgan has come under criticism recently for a spending spree during which it has failed to carry out proper due diligence, Bloomberg noted.
'This raises to the fore questions about whether JPMorgan is spending too much too fast,' Mike Mayo, an analyst at Wells Fargo told Bloomberg.
'The purchase price is less than half of 1 percent of this year's earnings, but it still stands as a potential microcosm of a broader issue that perhaps JPMorgan is wasting more money than desired as it pursues such aggressive spending,' he added.
Javice filed her own lawsuit against JPMorgan in the same week it filed theirs. She accused the bank of conducting 'a series of groundless investigations' into her conduct, saying it 'manufactured a for-cause termination in bad faith' in order to deprive her of a proper payout and 'retrade the deal.'
'After JPMC rushed to acquire Charlie's rocketship business, JPMC realized they couldn't work around existing student privacy laws, committed misconduct and then tried to retrade the deal,' Javice's lawyer, Alex Spiro, wrote in a statement to Forbes. 'Charlie blew the whistle and then sued. JPMC's newest suit is nothing but a cover.'
Frank's practices, however, have been called into question before. In 2020 Congress members wrote a letter to the Chairman of the Federal Trade Commission claiming that its standardized form for applying for federal relief funds would not be viable.
Specifically, it accused Frank of 'creating false hope and confusion for students while contributing to unnecessary extra work for financial aid administrators.'
It also made mention of the value of user information and data. 'We further suspect that the company may be using the data collected from misled students to make a profit by selling data to third party advertisers,' the Congress members wrote.
'In short, this tool does not make it any easier for students to get relief funds and appears instead to be a way for Frank to mine and exploit students' data for profit,' the letter concluded.
The development comes after the bank sued Frank's founder Charlie Javice and chief growth officer Olivier Amar. According to JPMorgan, the fintech firm tricked it into believing it had a client base of almost 4.3 million when in reality it had less than 300,000 clients.
