The story begins as Don Vito Corleone, the head of a New York Mafia family, oversees his daughter's wedding.
His beloved son Michael has just come home from the war, but does not intend to become part of his father's business.
Through Michael's life the nature of the family business becomes clear. The business of the family is just like the head of the family,
kind and benevolent to those who give respect,
but given to ruthless violence whenever anything stands against the good of the family.

@Jalex Stark Not that I now of. At some point @Ben McDonnell worked on it a bit.
But that shouldn't stop you at all from attacking it.
Note that we would first need that basics which shouldn't be done for finite groups, but just in general.

You might not like my suggestions. That's okay. But you still have to figure out how this principle applies to your situation. ---
Summary: Eric claims that if ISVs are unwilling to trust their customers, then they won't have any.
Reminding my readers once again that I am not a Microsoft employee, I observe that over the last year or two, the world has seen a different posture from the developer tools groups at Microsoft. They've opened up. The buzzword for this movement is "transparency". Some folks have told me that the leadership driving this concept comes straight down from Eric Rudder, Senior Vice President in charge of Servers and Tools.
This concept of transparency is visible in many different ways, including their Community Technology Previews and the Product Feedback Center. But perhaps the most obvious change is the ubiquity of weblogs by Microsofties of all kinds. Not that long ago I was habitually reading every weblog written by a Microsoft employee, every day. Today there are so many Microsoft weblogs I just can't begin to read them all. Only Scoble can read that much stuff. :-)
In this column, I want to closely examine this concept of transparency and talk about why it is so important, even for a small ISV.
If you really think about the nature of an ISV, selling software is an amazing thing. Throughout recorded history, most products have been tangible. When I buy land, I can plant corn on it. When I buy a table saw, I can use it to rip a board down its length. When I buy an orange shirt, I can be properly attired for an Illinois basketball game. These products are tangible.
 In fact, here at SourceGear, most of our sales never involve anything physical at all. Money flows in our T-1 line and products flow out. Sometimes it seems like magic. Customers are buying something completely intangible, and they're giving us real money for it!
However, as the old saying goes, money doesn't grow on trees. Whether the customer is buying software or guns or butter, all product buyers need to have a certain level of confidence and trust before they can make the difficult decision to part with their money. Speaking as a consumer, I need to feel different levels of trust for different kinds of products. Buying a car is a very high-trust deal. Buying paper clips? Not so much.
I observe that buying software is closer to the "high trust" end of the spectrum. When people buy software from your ISV, they are expecting a lot from you, both now and in the future:
So, by asking customers to pay for your software, you are asking a lot. You are expecting them to trust you. But how much do you trust them?
Declaring my intention not to stretch this metaphor too far, I compare the ISV/customer relationship to a relationship between two people. Relationships don't work without mutual trust. If one side expects trust but is unwilling to give it, the relationship will simply fail.
So often I see software entrepreneurs who don't want to trust their customers at all. It is true that trusting someone makes us vulnerable. Just as in a human relationship, trust is a risk. We might get hurt. But without that trust, the relationship isn't going to work at all.
Transparency is an ISV's way of trusting your customers. By letting your customers see behind the corporate veil, you extend them your trust, making it easier for them to trust you in return.
Here in the Midwest there is a restaurant chain called Steak-n-Shake that seems to understand transparency. Their slogan is "In Sight It Must Be Right". The idea is that if you let your customers watch you prepare their food, you can't slip anything funny into the burger.
If this doesn't make sense yet, please bear with me. In the following sections I will discuss eight ways that ISVs can trust their customers by being transparent.
When I am a customer of another ISV, I want to see weblogs:
Weblogs give me a way to see the people behind the products.
Noting that weblogs come in all flavors, I want to clarify what I mean. Lots of weblogs are written by individuals who feel compelled to tell the world what they had for breakfast and whether they found a way to get laid last night. Others keep a weblog to write about their religious or political views, or to provide extended family with daily pictures of their kids. These are not the kinds of "blogs" I have in mind.
The style I am recommending here is what most people would call a "corporate weblog". The goal is to give the world a personal glimpse of the people behind the product, but not to get too personal. Let people see who you are, but stay mostly on topic. The point is to write about your company and your products, not about the arcane details of your life.
If you are working in a small ISV, consider writing a weblog, but please do go into this challenge with your eyes open. Writing a good weblog is harder than it looks. It takes a lot of time and effort. But when it's done right, a weblog can be an excellent way to make your company a bit more transparent.
Together, you and your customers form a community. What kind of community do you want to be? Do you want to live in a neighborhood where everybody stays in their house to watch "Law and Order" reruns? Or would you rather get outside, enjoy the air, compliment your neighbor's lawn, and commiserate about the price of gas?
One of the easiest and best things you can do for your customers is to give them a place to talk. People like to talk, especially when they have something in common. A simple Web-based discussion forum can provide a place for this to happen.
The great thing about this kind of forum is that it allows two kinds of communication to take place:
When everything works out just right, the result can be a huge benefit for you and your customers. An active community will increase the overall gravity of your products.
However, real community is a strange thing. You cannot really force it to happen, but you can definitely prevent it from happening. The basic guidance is to provide the infrastructure and clear the obstacles:
By the way, this seems like a great place to insert a gratuitous plug for my good friends over at Telligent Systems. If you need good software for weblogs or discussion forums, they've got what you need. (I have no connection to the company.)
Give your customers a place to talk about your product, even if you don't always like what they say. This is a great way to extend them your trust.
As I mentioned above, software customers usually want to know that a product will be steadily improved in the future.
There are exceptions to this rule of course. Last week I purchased a computer Scrabble game for about $20. In this case, future upgrades are not very important for me. I just want to play the game in its current form. Unless I find some horrendous bug, I don't really expect this vendor to ever provide me with an upgrade.
But most software products aren't like that. When people buy Vault from us, they often ask questions about the future of the product. They plan to be using our product for a long time, and they just want to know that we will be continually improving it along the way.
But not only do users want you to keep improving your product, they usually care about specifically how the product grows and matures. They want to be reassured that your product will be growing deeper, not just wider. I define these terms like this:
The usual way to make a product wider is to add more features. Reaching an entirely new segment of customers often means adding entirely new capabilities to the product. For example, we are currently in the process of adding Eclipse integration as a feature for Vault. While it is true that some of our existing customers have requested this feature, the primary motivation here is to reach out to new customers.
The problem is that ISVs can easily fall into the bad habit of always making their product wider without making it deeper. The connection between "new features" and "new revenue" is easy to see, but it's harder to make a business case for doing things that simply make your existing customers happy.
Yet, we know intuitively that if our customers are unhappy, we're going to be in trouble. So it is critical that you find time in your small ISV to do the things that keep your current customers happy:
So what's my point? Here it is: Companies that try to hide their product's problems are usually the ones that never fix them.
No software product is perfect. All products have problems. The only question is whether the vendor is fixing them or not. By being open about the problems in your product, you identify yourself as a company who is willing to be held accountable for getting those problems fixed. That's the kind of company that customers can trust.
First let me clearly say that I do believe it makes sense for most ISVs to implement some sort of mechanism to help users be compliant with the licensing terms of their product. I will call this mechanism "license enforcement code".
But let's not sugarcoat anything here. License enforcement code is a terrible waste. We spend time and money to design, implement and test it, just like any other feature of the product. However this "feature" adds no benefit for the user.
I therefore believe it is critically important to never go too far when including license enforcement code. The goal should simply be to "keep honest people honest". If we go further than this, only two things happen:
It makes sense to optimize your product for the honest users, since they are by far the most common case. License enforcement code should be simple and minimalist. By including license enforcement code, you are telling your customer that you do not trust them. Don't shout this message -- whisper it. Since it adds no value to the honest user, the best you can do is to cause them no harm.
All SourceGear products use a simple serial number scheme for basic license enforcement. We try to make this functionality completely painless. But I'll confess that we had to walk somewhat of a winding journey to get here.
When we released Vault 1.0, we included a "product activation" system that was designed to prevent people from using the same Vault serial number on two servers. We figured that even though everybody hates product activation, we could get away with it because Microsoft is doing it. ("It's not our fault! Microsoft started it!")
But things didn't turn out the way we expected. First of all, the Microsoft product activation scheme doesn't seem to work as badly as I thought. I still hate the idea in principle, but I have to admit that Microsoft's product activation has never caused me any real inconvenience. A few months ago I built a new PC for my home. I bought new copies of Windows and Office, and in both cases, the product activation Just Worked.
On the other hand, SourceGear's experience with product activation was very unsatisfying. The "feature" worked most of the time, but it was really frustrating in those times when it did not. On several occasions I found myself on the phone trying to help a customer who was having trouble with activation. It is one thing to have a customer who can't get the product installed because of a goofy configuration. But it is ten times worse to have a customer who can't install the product because of a glitch in our license enforcement code. Sometimes it felt really embarrassing.
Product activation increased our technical support load, annoyed our customers, and gave us more code to maintain. If we received any benefits from product activation, they were invisible. We ripped it out for the Vault 3.0 release. Not only does it make more sense to trust our customers, it's a lot less work.
This is so standard nowadays that I feel silly mentioning it: Provide a demo download so people can try your product before they buy it. I doubt that any serious ISV today would try to implement a policy where customers must always pay before even seeing the product.
Nonetheless, although there should be no question about "if" you have a demo download, there are good questions to be asked about "how" you manage it. The high-trust path looks like this:
The way you handle your online demo is another opportunity to express trust in your customer.
Perhaps the ultimate expression of trust for an ISV is a money-back guarantee. If for some reason they change their mind after making a purchase, they stop using the product and you give them back their money. It is typical to give them 30 days after the sale to make this decision, sometimes more. The motivation for this kind of policy is very simple: You are making it easier for customers to enter into a relationship with your ISV by eliminating all of their risk.
A money-back guarantee dramatically increases the transparency of your company. Now your prospective customer can see everything a customer can see. They can taste the product, sample the technical support and smell the purchasing process. If any of it displeases them, then they can just hit "Undo" and get a refund.
This kind of policy seems very risky, but anecdotal evidence consistently suggests that it's really not. I have spoken with quite a few ISVs who offer a money-back guarantee, and they all say the same thing: Very few people ever ask for the refund, but lots of people experience greater confidence about their purchase.
When I buy software from a small ISV, I usually wish I could know all kinds of things about the company's financials:
I suppose I am nosier than most. I know how the guts of an ISV work, so I always find myself wondering about all the gory details.
I am not suggesting that you divulge all of this information. However, sharing a few select tidbits can sometimes increase confidence for your customers. Lots of software companies don't survive. Customers want to know if your firm will be around for a while. If your firm is conservatively managed and operating profitably, let people know.
Conventional wisdom says you should never make a promise you cannot keep. That's good advice, and I agree with it 100%.
But some interpret this advice to mean that you should never make any promises at all. I believe we can do better. Customers really want to know about your future plans. They want to know what new improvements will appear in the next release and when that release will be available. When they ask these questions, surely there is something you can say?
Just remember to always under-promise and over-deliver. As long as you carefully stay within this boundary, consider talking with your customers about your plans for future releases.
Thus far, I have described a level of trust and vulnerability that may seem outrageous. In response to those who might (perhaps understandably) diagnose me as a raving idiot, I would say two things:
First, I don't necessarily expect every ISV to implement every suggestion I listed above. As always, please use common sense to figure out the degree to which my advice is a good fit for your situation.
Second, I don't expect any ISV to be completely transparent. Even if you act on all of the points above, there are still a lot of things that you probably want to hold private.
For example, customers don't need to know your actual revenue and income numbers. They don't need access to the internal databases you use for tracking work items or technical support tickets. They don't need to listen in when your team argues about the priority to place on a bug they reported.
Just as relationships do not function without mutual trust, they also do not function without healthy boundaries.
As I wrote this article, I had a crisis of conscience. I can honestly say that SourceGear today would score very well on 7 out of the 8 points above. However, the other one haunted me as I wrote this piece.
Since founding the company in 1997, we have been selling software products with a stated policy of "no refunds". We encourage our prospective customers to take full advantage of our 30-day demo period, liberally extending it when they need more time. We prefer that people spend plenty of time evaluating before their purchase so that we don't have to fiddle around with the hassle of refunds.
In general, this approach has worked, but it's not perfect. We occasionally get somebody asking for a refund even though our Web site clearly explains our "no refunds" policy. And the truth is that despite our apparently strict policy, we don't want money from anybody who doesn't love our products. We don't get many requests for refunds, but I can't think of a situation where we refused a customer who asked for their money back within a reasonable amount of time.
So our policy is inconsistent with our practice, and when refunds do happen, there is no standard procedure for handling them in a consistent manner. Furthermore, our stated "no refunds" policy just doesn't make us look very friendly. I suspect that for some people it raises questions about our trustworthiness.
It is time for us to change. Effective immediately, SourceGear's policy is to offer a 30-day money back guarantee. I won't bore my readers here with the details, all of which can be found on our company Web site. I share this story merely because my own journey on the subject of transparency may be instructive to readers.
After publishing an article, I often hear from people who want to discuss it with me. This time I would like to try and guide that discussion traffic into the right places:
I will close with one final piece of advice. Quibble over the details if you like, but don't avoid the main point of this article: You cannot expect your customers to trust you if you are unwilling to trust them. You might not like my suggestions. That's okay. But you still have to figure out how this principle applies to your situation.

Every day, people send 500 million tweets. Impressive, right? And that is just Twitter! In this immense volume of data generated on social media, there are mentions of products or services, stories of customer experiences and interactions between users and brands. For companies, following these conversations is vital to get real-time actionable insights from customers, address potential issues or anticipate a crisis. However, analyzing this data manually is not a feasible task. Topic analysis allows you to automatically add relevant context to the data obtained through social media, in order to understand what people are actually saying about your brand.
Organizations generate a huge amount of data every day. In this context, knowledge management aims to provide the means to capture, store, retrieve and share that data when needed. Topic detection has enormous potential when it comes to analyzing large data sets and extracting the most relevant information out of them. This could transform industries like healthcare, where tons of complex data is produced every second ? and it is expecting to see an explosive growth in the next few years ? but is hard to access it at the right time.
This is the era of data. Collecting and analyzing data from different sources (the so-called Business Intelligence) creates unique opportunities for businesses. By taking advantage of insightful and actionable information, companies are able to improve their decision-making processes, stand out from their competitors, identify trends and spot problems before they escalate. When it comes to market research and competitive analysis, artificial intelligence (AI) can come to the rescue! You can use topic analysis to sift through product reviews of your brand and compare them with those that mention your competition.
Teamwork is the ability to work together toward a common vision. The ability to direct individual accomplishments toward organizational objectives. It is the fuel that allows common people to attain uncommon results.

South Africa: Complete update of all national-level protected area records. This update has resulted in an increase in the quality of data for South Africa, including the reclassification of eight biosphere reserves as UNESCO Man and Biosphere Reserves, which were previously listed as nationally designated protected areas.
Togo: Update of protected areas attribute information for several site.
Myanmar: Complete update of all national-level protected areas. This is the first comprehensive update of Myanmar's protected area records since 2011, resulting in 12 new polygon and four new point records being added to the country's protected area network. The current information stored in the WDPA for Myanmar was also reviewed and updated to ensure an accurate representation of the country's protected areas.
Malawi: Partial update to protected area records for Malawi, resulting in updated boundaries for nine polygon records and updated data for one point record. This is the first update of National Parks and Wildlife Reserves since 2002.
Swaziland: Complete update involving the addition of one polygon record and updated boundaries for 20 polygon records. The new polygon record is for Lomati Nature Reserve (WDPA_ID = 555626094), which represents an area of 6.63 km2.
Finland: Added one new site, Linnunsuo which is a Private Nature Reserve , which is an example of a protected area conserved by a local community in Finland. The site is owned by a local NGO, but managed by the local community in collaboration with a government agency.
Ramsar Sites, Wetlands of International Importance: Addition of new Ramsar sites for France and Poland with updated Rasmar sites for Argentina, Myanmar and Swaziland. This update is part of a series of updates on Ramsar data within the WDPA, resulting from enhanced data flows between UNEP-WCMC, the Ramsar Secretariat and member states.
Spain: Update of IUCN Management category and Management Agency for nearly 4,000 sites.
We updated the "Sub Location" (SUB_LOC) field to standardised the field to use just semicolons (removing commas and spaces). We also corrected several errors in the assigning of the "Parent Country" (Parent_ISO3) for example several sites in Greenland were incorrectly attributed.

new MyAnalysis()
This file is a template for writing a custom Jalangi 2 analysis. Simply copy this file and rewrite the callbacks that you need to implement in your analysis. Other callbacks should be removed from the file.
In the following methods (also called as callbacks) one can choose to not return anything. If all of the callbacks return nothing, we get a passive analysis where the concrete execution happens unmodified and callbacks can be used to observe the execution. One can choose to return suitable objects with specified properties in some callbacks to modify the behavior of the concrete execution. For example, one could set the skip property of the object returned from MyAnalysis#putFieldPre to true to skip the actual putField operation. Similarly, one could set the result field of the object returned from a MyAnalysis#write callback to modify the value that is actually written to a variable. The result field of the object returned from a MyAnalysis#conditional callback can be suitably set to change the control-flow of the program execution. In MyAnalysis#functionExit and MyAnalysis#scriptExit, one can set the isBacktrack property of the returned object to true to reexecute the body of the function from the beginning. This in conjunction with the ability to change the control-flow of a program enables us to explore the different paths of a function in symbolic execution.
Note that if process.exit() is called, then an execution terminates abnormally and a callback to MyAnalysis#endExecution will be skipped.
An analysis can access the source map, which maps instruction identifiers to source locations,
using the global object stored in J$.smap
. Jalangi 2
assigns a unique id, called sid
, to each JavaScript
script loaded at runtime. J$.smap
maps each sid
to an object, say
iids
, containing source map information for the script whose id is sid
.
iids
has the following properties: "originalCodeFileName"
(stores the path of the original
script file), "instrumentedCodeFileName"
(stores the path of the instrumented script file),
"url"
(is optional and stores the URL of the script if it is set during instrumentation
using the --url option),
"evalSid"
(stores the sid of the script in which the eval is called in case the current script comes from
an eval
function call),
"evalIid"
(iid of the eval
function call in case the current script comes from an
eval
function call), "nBranches"
(the number of conditional statements
in the script),
and "code"
(a string denoting the original script code if the code is instrumented with the
--inlineSource option).
iids
also maps each iid
(which stands for instruction id, an unique id assigned
to each callback function inserted by Jalangi2) to an array containing
[beginLineNumber, beginColumnNumber, endLineNumber, endColumnNumber]
. The mapping from iids
to arrays is only available if the code is instrumented with
the --inlineIID option.
In each callback described below, iid
denotes the unique static instruction id of the callback in the script.
Two callback functions inserted in two different scripts may have the same iid. In a callback function, one can access
the current script id using J$.sid
. One can call J$.getGlobalIID(iid)
to get a string, called
giid
, that statically identifies the
callback throughout the program. J$.getGlobalIID(iid)
returns the string J$.sid+":"+iid
.
J$.iidToLocation(giid)
returns a string
containing the original script file path, begin and end line numbers and column numbers of the code snippet
for which the callback with giid
was inserted.
A number of sample analyses can be found at ../src/js/sample_analyses/. Refer to ../README.md for instructions on running an analysis.

Previous: Examples of NAMED clause, Up: Miscellaneous Clauses
The initially and finally constructs evaluate forms that occur before and after the loop body.
The initially construct causes the supplied compound-forms to be evaluated in the loop prologue, which precedes all loop code except for initial settings supplied by constructs with, for, or as. The code for any initially clauses is executed in the order in which the clauses appeared in the loop.
The finally construct causes the supplied compound-forms to be evaluated in the loop epilogue after normal iteration terminates. The code for any finally clauses is executed in the order in which the clauses appeared in the loop. The collected code is executed once in the loop epilogue before any implicit values are returned from the accumulation clauses. An explicit transfer of control (e.g., by return, go, or throw) from the loop body, however, will exit the loop without executing the epilogue code.
Clauses such as return, always, never, and thereis can bypass the finally clause.
return (or return-from, if the named option was supplied)
can be used after finally to return values from a loop.
Such an explicit return
inside the finally clause takes precedence over returning the accumulation from clauses supplied by such keywords as collect, nconc, append, sum, count, maximize, and minimize; the accumulation values for these preempted clauses are not returned by loop if return or return-from is used.

This tool determines the watershed, or upstream contributing area, for each point in your input layer.
For example, suppose you have point features representing locations of waterborne contamination and you want to find the likely sources of the contamination. Since the source of the contamination must be somewhere within the watershed upstream of the point, you would use this tool to define the watersheds containing the sources of the contaminant.
The location of your input points is important. If they are not located precisely on a drainage line, the resulting watersheds may be very small and not useful for your analysis. The Search distance to nearest drainage can be used to adjust the location of your input points so they fall precisely on a drainage line in order to find the watershed that flows into the point located on the drainage line. The adjusted locations used to find the watersheds are written to the output layer—your input points are not modified.
The result is a group layer containing two layers: the watersheds and the adjusted points used to compute the watersheds.
The resulting watersheds will have all of the attributes of your input points as well as these additional attributes:
If Use current map extent is checked, only the features in the current map extent will be used to compute watersheds. If unchecked, all features in the input layer will be analyzed, even if they are outside the current map extent.
A watershed (the upstream contributing area) will be calculated for each point.
In addition to choosing a layer from your map, you can select Choose Living Atlas Analysis Layer or Choose Analysis Layer found at the bottom of the drop-down list. This opens a gallery containing a collection of layers useful for many analyses.
If your input points are located away from a drainage line, the resulting watersheds are likely to be very small and not of much use in analysis, such as determining the upstream source of contamination. In most cases, you want your input point to snap to the nearest drainage line in order to find the watersheds that flows to a point located on the drainage line. To find the closest drainage line, specify a search distance. If you do not specify a search distance, the tool will compute and use a conservative search distance.
To use the exact location of your input point, specify a search distance of zero.
For analysis purposes, drainage lines have been precomputed by Esri using standard hydrologic models. If there is no drainage line within the search distance, the location containing the highest flow accumulation within the search distance is used.
This is the name of the layer that will be created in My Content and added to the map. The default name is based on the tool name and the input layer name. If the layer already exists, you will be asked to provide another name.
Using the Save result in drop-down box, you can specify the name of a folder in My Content where the result will be saved.

Explaining Your PostgreSQL Data
I’ve written a bit before about understanding the output from EXPLAIN
and EXPLAIN ANALYZE
in PostgreSQL. Though understandably getting a grasp on execution plans could probably use some more guidance.
Getting at the Data
The first small thing you can do is actually retrieve the data in JSON form. By adding in (format json)
right after your EXPLAIN
or EXPLAIN ANALYZE
command it’ll as you’d expect return it in JSON. To give an example:
# EXPLAIN SELECT * FROM users LIMIT 1;
QUERY PLAN
--------------------------------------------------------------
Limit (cost=0.00..0.03 rows=1 width=812)
-> Seq Scan on users (cost=0.00..1.50 rows=50 width=812)
(2 rows)
Then in JSON format:
EXPLAIN (format json) SELECT * FROM users LIMIT 1;
QUERY PLAN
------------------------------------------------
[ +
{ +
"Plan": { +
"Node Type": "Limit", +
"Startup Cost": 0.00, +
"Total Cost": 0.03, +
"Plan Rows": 1, +
"Plan Width": 812, +
"Plans": [ +
{ +
"Node Type": "Seq Scan", +
"Parent Relationship": "Outer",+
"Relation Name": "users", +
"Alias": "users", +
"Startup Cost": 0.00, +
"Total Cost": 1.50, +
"Plan Rows": 50, +
"Plan Width": 812 +
} +
] +
} +
} +
]
(1 row)
While its on my list to build some interesting apps by pulling in the JSON input, others may be equally as interested in taking advantage of this data in its JSON form. If you take a shot at building something with this output, as always I’d love to hear about it –<EMAIL_ADDRESS>Despez
Of course if you’re itch isn’t in better tools for Postgres, you may just want to have a solution that works today. While its not perfect, one of the best ones out there is Dezpez’s explain tool. You can take any execution plan and paste it in and get some better visual representation of the result. You can also share them as well.


Xiaomi Redmi Note 8’s best feature isn’t its quad-camera setup — it’s the battery
by Ivan MehtaXiaomi‘s Redmi series of phones have been its main money-maker in India. The company now sits at top of the Indian smartphone chart thanks to spectacular sales of devices released in this series.
It released its marquee Redmi Note 8 Pro last month with a quad-camera setup led by a 64-megapixel sensor.
Specifications
- Screen: 6.53-inch full HD+ display
- Processor: MediaTek Helio G90T
- RAM: 6/8GB
- Rear camera: 64–megapixel + 8-megapixel wide sensor+ 2-megapixel depth sensor + 2-megapixel macro camera
- Front camera: 12-megapixel sensor with f/2.0 aperture
- Internal storage: 64/128GB
- Battery: 4,500 mAh
- Software: Android 9.0 Pie with MIUI 10
Just so you know, I’m using the 8GB+128GB version for this review.
What has changed?
Xiaomi has traditionally relied on a mid-range Qualcomm processor for its Redmi series in India. However, the company switched it up this time with a newly launched gaming-focused MediaTek Helio G90T processor.
The Redmi Note 8 Pro has a completely revamped camera setup as compared to the Redmi Note 7 Pro with dual camera. The 48-megapixel main sensor is replaced by a 64-megapixel main sensor. And instead of a single 5-megapixel depth sensor, there is a 2-megapixel depth sensor. The device also gains a wide-angle and a macro sensor.
What’s good?
First things first. I absolutely love this device’s battery life. If you use it moderately, you can easily get two days of usage with a single charge. I regularly play Pokemon Go, which drains a lot of battery. Despite that, I regularly got more than a day’s battery life out of it. Thankfully, Xiaomi includes an 18W charger in the box. So, you can quickly top up the charge at any point.
I quite like the phone’s design and color of my forest green variant.  Performance-wise, MediaTek’s Helio G90T does its job. It held up well when I played games such as Call of Duty Mobile or Pokemon Go. There was no major problem when I was switching between apps, surfing the web, or streaming videos.
The phone’s 64-megapixel main sensor captures a good amount of detail if there’s adequate lighting. The colors are not always oversaturated – a tendency that previous Redmi smartphone cameras had developed. The phone shoots decent portrait shots and good selfies if you turn off the beautification filters.
What can be improved?
Despite having impressive hardware, Xiaomi‘s phones can be annoying to use sometimes. And MIUI’s inconsistencies are a big factor contributing to that. When you boot up your device for the first time, you’ll find a ton of pre-installed apps. While you can uninstall most of them, it’s hard to find them once your apps also sync up. It would be useful if Xiaomi organized them into a folder at startup.
As I mentioned in my review of the Redmi K20 Pro, MIUI doesn’t do a good job at filtering out notifications. Sometimes, I don’t get notifications on time, while other times, there is a trove of notifications that are of no use. Then there are a couple of annoying notifications that are pinned to the tray. For instance, I use my phone as a hotspot when I’m on the move. Due to how MIUI is designed, the hotspot notification plays a tone every time when a device is tries to connect with it, and I can’t even swipe it off.
I also wasn’t impressed with how the phone handled automatic brightness. It can be just my review unit, but often I found the phone didn’t turn up the brightness when I was out or screen visibility was low.
Let’s talk about cameras. While four cameras provide great versatility and options, wide-angle and macro camera fail to produce expected results often. The former struggles in anything but daylight. These photos might fly on social media when you apply a couple of filters, but if you’re a keen observer, you’ll see saturated colors and loss of details. The macro camera can be fun to use, but it’s hit or miss in terms of getting the focus and details of the object in your viewfinder right.
Who’s it for and what’s the competition?
The Redmi series of phones have been reliable purchases for those looking for the best things a smartphone has to offer at a pocket-friendly price. The Redmi Note 8 provides great performance and killer battery life. And if you’re not a stickler for amazing photography, it gives you decent enough options to shoot versatile photos.
At the moment, only RealMe XT sports a 64-megapixel sensor other than the Note 8 Pro. However, The Vivo Z1 Pro with a hole-punch selfie camera and 5,000 mAh battery can also give some tough fight to the device.

General State-Space Controller class.
See "example_StateSpaceController.cpp.example" to have an implementation example.
Assuming K is the controller:
K: | x_{i+1} = A*x_i + B*e_i | u_i = C*x_i + D*e_i with e_i = r_i - y_i
QSMatrix class can be totally unused by user if a data file is generated to import the controller matrices. See loadControllerData() or StateSpaceController::StateSpaceController() for file format and more details.
This class can be used as a state space controller alone or coupled with a comparator to generate the error vector by using overloaded member functions.
