3 tips for preparing wireless networks for IoT

To summarize :
  • Taking care of security
  • Track IoT Traffic
  • Use your IoT network data to create business value information
Most business leaders believe that the Internet of Things (IoT) offers a tremendous opportunity for their organizations to promote new business models, improve customer relationships, increase efficiency and productivity . An Oxford Economics study shows that 72% of organizations believe that IoT is essential to their competitive advantage.
But success with the IOT requires attention to networks, especially wireless networks. According to an IDC survey published last February Wi-Fi and Bluetooth Low Energy (BLE) are the main competitors to implement IoT connectivity. What should administrators and network managers do to prepare their wireless networks for the IoT? Here are three good tips.

1. Take care of safety

Last year the emergence of the Mirai botnet awakened organizations to the possibility that IoT devices could be used in cyber attacks. Network administrators must therefore ensure that attackers do not use IoT devices in an organization to enter systems or integrate IoT devices into botnets to attack other networks.
The most common error is to allow connected objects to access networks using a weak password or a single PSK (Pre-Shared Key). This is an important point because many Wi-Fi hotspots are currently set to default either in WPA in shared key mode (PSK) with TKIP encryption, or in WPA2 in shared key mode with CCMP encryption.
It is therefore recommended to use more advanced security solutions to validate IoT devices and provide visibility into what is connected to the network. This visibility can also help to better manage networks.

2. Track IoT traffic

Not only do network professionals need to secure their WLANs, they must also be able to control the IoT devices that connect to Wi-Fi, the amount of bandwidth and other resources they consume.
One of the biggest problems for network administrators is that they do not know how many IoT devices are on their network. Often employees add devices to the network without any specific knowledge of computing and its security and management constraints. The ISD must therefore ensure that it has network management and monitoring tools that will enable it to identify the connected devices and with whom they communicate. From this point of view identity is really the main focus of any security and management policy.

3. Use your IoT network data to create business value information

For many companies, IOT projects must collect data that will help them gain commercial benefits in one way or another. In this perspective the data of the network as well as the data of the IoT sensors can make it possible to generate knowledge. For example, in a store or restaurant, data on the number of smartphones and other devices connecting to the wireless network can help determine when more cases should be opened.
By using location, presence, configuration and identity via APIs over the WiFi network, it is possible to create important information to guide the business.

5 tricks to kill e-mails that do not work in business

To summarize :
  1. Do not get emails in the morning
  2. Four sentences (or less)
  3. Organize stand ups
  4. Use the walls
  5. An internal blog
We hate the heaps of email that kill our inboxes in the morning. Especially when shippers sit a few meters from our office. Some organizations are trying to suppress what many of us consider a nuisance. Without real success.
While accepting it as a necessary evil, here are 5 ways (and yes, we voluntarily slack Slack, because everyone knows this type of solution) to reduce the bureaucracy of e-mail, make office life more Supportable, and your organization more efficient.

1. Do not get emails in the morning

A tip of method to get started. What do you do as soon as you arrive at the office in the morning (or as soon as you look at your smartphone)? You check your mail. Of course. What if you did something else instead?
A good hour of work can be carried out before the consultation of the mails: read files, write documents, ... There is so much to do. Then, put yourself in mail. It is even possible that your morning work helps you better respond to e-mail requests.

2. Four sentences (or less)

This is an arduous rule to follow but which must make it easier to read e-mails. Http:// is a simple method that is inspired by SMS and Twitter: four sentences per answer to a mail, bar. The aim is to increase the effectiveness of communication.
Anyone who sends and receives information from their computer or smartphone on a daily basis knows just how simple this rule can help. For the most radical, you can look here: or there: . And for those who are reticent, here is what to find (a little) more flexibility: . Of course, the brevity of a message can not escape the essential rules of grammar and courtesy.

3. Organize stand ups

And if less email went through more face-to-face meetings? We do not advocate the meeting, consequence of a deleterious governance and comfortable chairs. Our developer team meets every morning standing and cup of coffee in hand in a corner of the open space. Objective: that everyone says in 30 seconds where he is on his project or projects in progress. What to shun number of unnecessary emails in a few words.
Little joke, no gossip, no digression. Sharing useful information about sprints in progress at the navel, simply a sharing of jobs, work to be done and everything related to current projects or sprints. This type of meeting in "standup" mode is quite characteristic of agile teams.

4. Using walls

Whether they are leprous or white as snow, the walls of your premises are spaces to occupy. Places where you can view the status of your projects and display the most important information for employees. That's enough to spare some emails there too.

5. An internal blog

But if the walls have the floor, hard to make them bear a conversation. Hence the numberless "reply" that blister the mail boxes. And the confidentiality of e-mail is a problem in itself. Difficult to look in the history, difficult to follow the evolution of a project by consulting the mails.
Automattic (the parent company of WordPress) uses an internal blog to manage projects. A blog ? Not just any blog. The P2 theme ( to try here ) is a kind of in-house microblogging, with comment and search features included. What to keep a history of a draft also.
And if you really care, then yes you can use Slack , or Microsoft Teams .

What are the 5 things to know to create a new Wi-Fi network in business?

To summarize :
  1. Put the price or you will pay the consequences
  2. It is still relevant to plug in some equipment
  3. Professional equipment if nothing
  4. Test before beginning to attach equipment to walls and ceilings
  5. Schedule scalability
The loyal readers know that I am equipping the PC Doctor HQ with a new Wi-Fi system. The old one was aging, worn and rudimentary, over-tapped from old hardware, with routers Plugged into other routers and a hodgepodge of Wi-Fi repeaters added to the set for good measure.
Five years ago, this system was fine, but as it became increasingly popular and the number of customers exploded, it began to crumble under the weight of demands Addressed and it was time to do something. So I picked up the sleeves and got on with the task. I have already mentioned here some of the equipment I installed (I will come back to shortly), but today I wanted to share some lessons I learned while creating the network.

1. Put the price or pay the consequences

As the old adage says, you have the choice between enduring once the payment of a good tool or suffer the consequences whenever you use a cheap tool. We spend thousands of dollars in smartphones, tablets and PCs, but then we rely on a cheap router for the internet connection.
After spending years tweaking using spare routers as access points and trying to eliminate Wi-Fi breakpoints using repeaters and these horrible CPL adapters (keep your money, they are not worth Nothing, you will thank me later for this good advice), I must admit today that the result of this infrastructure tinkered is a poor network. In addition to the poor performance, it becomes very painful to try to manage such a network.

2. It remains relevant to connect certain equipment

Although today, almost everything is wireless, it remains relevant to use Ethernet connections on devices that need to handle high-throughput loads, such as NAS enclosures and some desktop PCs. Not only does it reduce the load on the wireless network, it also gives these devices a more reliable connection (even if your Wi-Fi network should be relatively stable).
My main workstation is connected via Ethernet, as are my NAS enclosures and my Apple Time Capsule. If you do not want to have Ethernet cables that run anywhere in your office, home office or home, the easiest way is to place your wired device near your router or gateway.

3. Professional equipment if nothing

The professional wireless hardware beats the consumer material to flat stitching. There is no comparison, not only in terms of performance and reliability, but also support and updates.
I am very satisfied with the hardware I have installed. I am particularly impressed with the access points. The coverage offered far exceeds that of routers even of commercial quality. Moreover, these access points can be mounted on a wall or ceiling, powered by the Ethernet cable using a switch or an Ethernet power adapter (PoE); In other words, no additional power supply is required. In addition, the configuration and monitoring software allows you to configure the channels, signal strength and packets sent and received on each access point. You can also keep an eye on clients connected to the network.
These access points can also perform spectrum analysis to detect interference and find the best channels to operate on.

4. Test before beginning to attach equipment to walls and ceilings

Test the locations for Wi-Fi hotspots and routers before you begin to drill holes, pull cables, and ultimately make your installation permanent. Do this even if it involves running temporary cables on site to get an idea of ​​the strength of the signal before you start drilling holes all over the place.
It's strange how moving an access point about 30 centimeters can make a big difference on the signal in adjacent rooms or even change the coverage so you will need fewer access points (I discovered that I could cover the rooms on two floors using the same access point, whereas before I had to manage the floors separately).

5. Plan for scalability

If you want your network to last a few years, you should plan for scalability right now. This involves not only ensuring that you have free Ethernet ports on the switches, but also the ability to allow new wireless devices to connect to the access points.
Even the access points you chose to install are important. If you use PoE technology to power the devices, consider the load your switches will absorb. It is generally cheaper to buy a better device today than to have to trade all your equipment for a more recent equivalent in the future.
If you are using cables, ask yourself if you would be better off drawing category 7 cables today to ensure the durability of your installation. In the long run, you will save time and money.

Additional advice: give yourself plenty of time

Setting up a new Wi-Fi network takes time, so try to find a period of time when you are not under heavy pressure. If possible, deploy the Wi-Fi network in parallel with your existing installation, so that you will not be deprived of internet connection in the meantime.
You also commit to the tedious reset of all your devices (use this opportunity to change the Wi-Fi passphrase), which will give you the impression of being interminable (especially if you have The internet of the objects because they can be very troublesome to connect to a new network).
Believe me, when I tell you, there will be nothing good to show too much haste.

Although good security practices recommend that you have the latest versions of the software installed, the computer history sometimes forces you to bring out an old program or drivers for antique hardware. Where to find computer antiques? Here are five ways to help you.

OldApps: the must

Offering download files for software and operating systems for machines running macOS, Windows or even Linux, OldApps offers to find the applications of your choice by a clever search bar.

The home page, which is very dated as well as on all of this type of site, is well organized in categories regrouping versions of operating system, versions of web browsers, applications of utility type or even of various drivers. Offering several sources of downloads on most files available, its enormous catalog makes it a must.

The OldApps website

OldVersion: the alternative

OldVersion is a suite of files to download, even if there is little language to translate. Offering software on Windows, Mac or Linux, the site also allows to find old games and rarity, old versions Android.

Offering free download of almost 2000 programs, you can recover the majority of files from different sources (and multiply the chances of not having links obsolete). With a search bar as well as a classification by category and operating system, you will surely find here the application you were looking for.

The site of OldVersion

Apple: download at source

If you are using an older Apple product, you may be interested in purchasing directly from the source by going to the brand support. Indeed, you will find numerous updates of software produced by the firm dating after 1998 on the official website of the latter. ITunes, Mac OS, Pages and other iPhoto will be found through a search bar.

The only downside, the non-exhaustive nature of the site, but the reliability of the downloads will ensure you do not open a corrupted file. The ability to retrieve old specialized software like Final Cut Studio is a plus.

The Apple site for support

Download-Freeware: the French version

As its name suggests, Download-Freeware is a site for downloading free old versions of free applications and other open source and abandonware software. With a catalog less supplied than its competitors, the main advantage of this page is to be entirely in French and to offer more software in French version (which is more rare when it comes to old versions of applications ).

A description describes the function of the application, the operating system required and various links or information about the application. The site also has a forum even if the latter is somewhat abandoned.


MSDN: the key to your PC!

Belonging to Microsoft, MSDN proposes essentially manages relationships and interactions with various developers. In addition to downloading old versions of Windows and development tools from the firm, you will have the option to download official keys and patches to install these.

Today renamed Visual Studio, you will have to go through the old platform of the site to download these development tools. In any case, it will take a subscription to start the download, but you can do it from the free subscription Visual Studio Community.

Digital transformation at the service of energy transition

This week we could not miss Viva Technology, which, for its second edition, returned to vibrate innovation and global technology in the heart of Paris, with still a majority of French nuggets.
But technology is nothing without usages , even if it is a fireworks display.
It was easy to forget it by going through these paths occupied by robots, drones, the craziest applications of virtual reality or listening to the hubbub of the promises of the Artificial Intelligence. As for a July 14, it was a parade of innovation and technologies that demonstrates France's ability to mobilize around digital.
Now, let's imagine this surge of innovations, technologies, and energy of our young starters , to address a concrete problem that will concern more than 70% of the world population in 2050, city dwellers . It is said that nothing can resist him.
This problem is that of the environment and the energy transition which is before us but the first signs are already visible: traffic congestion, air pollution, energy bulimia ... as many common problems as the big ones Cities will have to resolve.
The troops mobilized to solve it are those of DataCity , coordinated by NUMA , to mobilize the intelligence and innovation of small and large companies in order to reinvent cities by exploiting their data.
The data is being discussed all the time - and nobody will dispute the entry into the data economy era - but how to collectively mobilize them for a common cause is the less trivial question that this program.
DataCity , an open innovation program, is therefore the simple idea that the sharing of data at the level of a city makes it possible to reinvent it by developing new services and optimizing its overall functioning.
For example, the analysis of the location of tweets at night, or anonymous data from operators to optimize urban lighting where it is needed, or to identify nightlife Adapt the security offer to these areas. Another example is that when individual traffic is down in the city, this benefit is offset by the 15% annual increase in e-commerce and deliveries, which are increasingly rapid. How to optimize these deliveries?
Generally speaking, cities need to know more about urban flows in real time and in the long term , thereby opening up new ways of managing and organizing services to optimize these flows, but also to deliver new services to the inhabitants Like being able to tell them if it is already too late to leave their trash bin or if the truck has not yet passed.
On 6 June, Anne Hidalgo , the mayor of Paris, opened the "Datacity Demo Day", a ceremony held in the festive hall of the town hall (over 600 people). Motivated all these teams for 8 months to come on this day proudly present their results.
Projects that combine all the available technologies and all the data of the operators of the city, for new uses that reinvent mobility in the city or the energy efficiency of buildings and the city as a whole. Within these projects were startups who have chosen to confront their innovations and technologies with concrete cases and to meet the challenges posed in each area by 9 large companies. The latter are operators or developers of the city (5 for the first edition in 2015), such as Bouygues Energie Services , La Poste , Nexity , RATP or Suez .
A way of moving from technology to use and aligning challenges to the greater cause of city sustainability, to make everyone contribute to that common goal. 

At the end of these prototype tests by startups, companies and the city of Paris benefit from the solutions, and the industrialists plan to deploy these systems in other cities where they are present.
The global economy of the given does not stop at the great gate of the city.
To invent urban services, it is now necessary to analyze large databases, public or private, with a lot of local data. This is where new "machine learning" technologies become more important.
But the challenges to this approach are enormous, such as the protection of personal data, respect for the general interest.
And at the same time, the salaries of datascientists are flying and economies of scale are likely to bring out only a few (global?) Global platforms that will only have the most advanced algorithms. 
But the challenge is met by the cities and a collective and cooperative approach with the operators is certainly a response to this challenge. This DataCity approach goes beyond the only logic of opendata generally implemented, because it couples to an approach of open innovation and it seeks an economic model.
This DemoDay could not better fall just after the announcement, challenged throughout the World, of the American President, not to implement the Paris agreement on climate. The C40, which brings together the 40 largest cities in the world, including the Mayor of Paris, currently holds the presidency, has decided to retaliate and maintain its commitments for Climate. In the tools at their disposal, the DataCity program, already replicated in Casablanca, will therefore be brought to be deployed in these cities .
The way data - and all digital - can be mobilized to help achieve environmental goals is not new, but GreenSI thinks it is now better perceived by all.
Digital technology is the engine that makes a set of solutions emerge in mass , without, however, finding their origin in the response to a common problem. A "cacophony technological" more and more palpable through the press and the specialized salons.
Moreover, digital has even more potential with the transition from the known Internet to that of connected objects and the mass analysis of the data by algorithms allowing analyzes to become faster and more predictive .
The energy transition is a common challenge , sometimes lacking a driving force to build answers. International agreements are essential to start this engine and cities are taking over.
Digital technology is therefore undoubtedly one of the driving forces behind the ecological transition.
But digital will also have to respond to the problem it creates itself in terms of electronic waste and energy consumption.
To do this,  digital technology will have to become greener (Green IT) , a subject for GreenSI not yet enough in the spotlight of the press nor taught in schools, and especially by putting its technologies at the service of a more efficient and sustainable management Of resources (IT for green) as DataCity demonstrated twice that it was possible.
What we observe with this approach, beyond technology, is the emergence of equally essential ecosystems that work together and coordinate. The digital roadmap in the city should therefore be built around three axes to "motorize" the energy transition:
  • Open data , to find a collective utility and concrete services, beyond the discourses of sovereignty and egos sometimes carried by the open data.
  • Smart "tools , which rely on this data to optimize processes and imagine new uses. The collaborative economy has shown the way and already changed the way to move with car-pooling.
  • But above all "agile" and thus iterative approaches at the local level, in response to the complexity and interdependence of the ecosystems concerned. It will certainly be necessary to invent a new urbanism to reconcile long-term planning with short-term agility.
The city of tomorrow will necessarily be sustainable and digital transformation is already at its service to meet the challenge. Let us hope she succeeds.

Fairphone launches open version of Android 6

The Dutch manufacturer Fairphone launches Fairphone Open, an open version of Android 6 Marshmallow. It says that this version of Android, with open source code, is delivered without the Google mobile services (Google Mobile Services, GMS) while the standard operating system of Fairphone comes with these options.

"Fairphone Open relies on the same support modalities, regular updates and security guarantees as the standard Fairphone OS."

Choosing apps and services

The company intends to leave "the choice of users between two operating systems developed by Fairphone, allowing everyone to freely choose the applications and services they want to benefit from." By publishing the source code, Fairphone encourages free participation in The Fairphone 2 ecosystem. This has already enabled the Fairphone community to rally various operating systems on the Fairphone 2 independently, including Lineage OS (with Android 7), Sailfish OS, Firefox OS and Ubuntu Touch from UBports.
Fairphone launched in early 2016 , a website in open source and development containing the code for the Android open version of the Fairphone OS. Henceforth the site hosts the code for the latest Android 6 Open operating system. "
The company also announces its partnership with the French search engine Qwant , "which protects the privacy of its users by refusing any tracing device for advertising purposes", to integrate it into its model " Fairphone 2. " Designed and Developed in France, Qwant offers a more ethical search engine and does not keep track of queries carried out, "said the manufacturer.

Little Thumb 

Launched in 2013 , Fairphone is campaigning for a "fairer electronics", sourcing metals from conflict zones and having its machines manufactured in a Chinese factory with the right wages. In this way, the company wants to act against the backdrop of major manufacturers whose behind-the-scenes are often not very environmentally or socially sound .
(Tout) Tiny Thumb in the smartphone sector, Fairphone said it has sold more than 130,000 smartphones to the European market so far. In a worldwide market of about 1.5 billion units a year, it is obviously tiny, but the company has a militant as much if not more than economic goal: it was born from a campaign in 2010 of associations On the origin of ores used in aircraft, often coming from war zones and financing conflicts.
According to Fairphone, the complexity of smartphones makes its task difficult ( Le Monde diplomatique in March 2016 devoted a major article to the difficulties of the company especially in labeling), making the "ethical and fair" More than a completed result.
Bibi Bleekemolen, director of Fairphone value chain development, whom I met last year, explained that a smartphone contains about 40 different ores and metals in hundreds of components:

"We know the origin of the raw materials for some of the components, and we are trying to increase their number, and we focus on gold and the three T's, tin [tin] , Tantalum and tungsten. "
