Cost Comparison - Optical Fiber vs Copper Cables

The cost of implementing a fiber optic network has dropped significantly over the past few years, so that revealing comparisons with other transmission lines such as twisted pair and coaxial cable systems are finally possible splicing fiber optic cable.

As long as cameras and monitors are not equipped with both coaxial connectors and optical 'ST' connectors, fiber optic lines will always suffer from additional costs associated with the cost of external components of the path. This is especially true for short-haul communication lines, where the cost of additional switching equipment is a significant proportion of the total. However, for lines longer than a few hundred meters, fiber optic systems are becoming increasingly attractive because the cost of coaxial cabling does not increase in direct proportion - either because of the need to use higher quality cables, or because of route amplifiers, or both.

Thus, there is always a line length, most likely between 500 and 1000 m, above which the use of closed-loop TV systems with fiber-optic communication lines is justified from only one point of view of costs. If the average line length is significantly less, and the minimum cost of the transmission path is your only criterion for choosing a physical transmission medium, then the use of fiber-optic lines is unlikely. On the other hand, if other factors are important, such as image quality, lack of interference and pickup, significantly less problems with drift, then why not consider using optical fiber in your system? You might be pleasantly surprised.

Optical Loss Budget

It may seem odd that the optical loss budget is calculated at such a late stage in the development process, but in fact, it can only be calculated with any accuracy after the cabling infrastructure is fully defined. The purpose of the calculation is to determine the loss for the worst-case signal path (usually the longest) and to ensure that the equipment chosen for the transmission path with a reasonable margin fits within the obtained limits.

The calculation is quite simple and consists in the usual summation of the losses in decibels of all components of the path, including the attenuation in the cable (dB / km x length in km) plus both connectors and the joint loss. The biggest challenge is simply extracting the required loss figures from the manufacturer's documentation.

Depending on the result obtained, the equipment selected for the transmission path may need to be reevaluated to ensure acceptable losses. For example, it may be necessary to order equipment with improved optical parameters, and if such equipment is not available, consideration should be given to switching to a transparency window with a longer wavelength, where the losses are less.

System testing and commissioning

Most fiber optic installers provide optical test results for a commissioning fiber optic network. As a minimum, they should include the end-to-end optical power transmission measurements for each fiber optic link - this is equivalent to a continuity check for a conventional copper network with electrical signal multiplexers. These results are reported as line loss in dB and can be directly compared with the technical data for the equipment selected for the transmission path. It is generally considered normal to have a minimum 3 dB loss margin (hardware promised minus measured value) of 3 dB for the inevitable aging processes occurring in fiber lines, especially in transmitters.

Many installers also provide OTDR (Time Domain Reflectometry) test curves - best thought of as a graphical record of the attenuation in each fiber - that can be saved for later comparison and analysis. Measurement graphs give OTDR invaluable information, however, nevertheless, they can only be an addition to measurements on end-to-end transmission of optical power, but not a replacement for the latter. This is due to the fact that the information obtained during reflexometric measurements is too complex for non-specialists to understand, has limited accuracy and is prone to distortion due to various defects in the fiber.

Under normal circumstances, only a minimal set of system acceptance procedures is required to verify that the receivers in the system are providing AGC, thereby eliminating any need for manual gain adjustments.

What's in the title and what's in the certification track? - Cisco Systems - 2021

When I read the "Unofficial" announcement of the new CCNP Wireless, I thought that this is just another area where Cisco, at the moment, is constantly at odds. I joke about it because there are so many classes I teach. In this case, use the "no" command against the "clear" command that you used last. In any case, looking at professional level certificates, you will notice CCNP, CCSP, CCVP, CCIP and probably (based on ads) the new CCNP Wireless network cisco voip certification. 

Could this be inconsistent because of how close CCWP (I think it should be called) would be to close the acronym to neutral CWNP provider certification? I guess that's the point at this point, and we'll have to wait to see what the official announcement on CiscoLive brings. I still have my opinion on the sequence of compositions. CCENT is the beginning. Then CCNA. With CCNA you can go directly to CCNP, but to make CCSP, CCVP or soon become a Wireless Professional, you must specialize in CCNA, CCNA Security, Voice CCNA or CCNA Wireless. 

I personally would like to see a certain sequence. Allow the CCNA routing and switching required before CCNP to be set. You can focus more on networking solutions, as it applies to Cisco solutions, as well as unified communications, mobility, and security. If you are unfamiliar, the following link shows the solution on the Cisco website. 

Cisco Network Systems Solutions However, if you take a closer look, you'll find products that are detailed in the Network Systems solution, including routers, switches, network management and iOS software. All of this is important for a CCNP candidate because the track focuses on routers, switches, and IOS software functionality. Another key aspect of the associated specialization is that they not only cover Enterprise-class devices that would be ISR routers and local / fixed LAN switches for CCNP, but they also cover devices designed to deploy small branches. 

With CCNA routing and switching, you can cover fast series switches as well as 500 series routers. All are designed as part of the Smart Business communications system. Again, these are my personal thoughts, but anyway I'm going with the tide. I think the Learning @ Cisco people are doing a great job of bringing the curriculum to market, as complete as it is. I look forward to the official announcement on CiscoLive

What are the differences with a patrimonial civil society?

By definition, a patrimonial civil society is a civil society whose corporate purpose is the management and transmission of heritage . This can be in the form of real estate or securities.

The various forms of civil society discussed above have notable differences with what is called a patrimonial civil society or SC Pat.

If a classic SCI allows for example to carry out activities of management of real estate assets, a patrimonial SC makes it possible to extend the corporate object to the management of transferable securities which have a patrimonial character , that is to say , which can be transmitted between associates. The latter can be part of the same family, as in the case of a classic SCI.

Thus, the activities of a patrimonial SC can extend to the following areas : freelance engineering

Sale of real estate with a view to making investments or investments (financial assets, etc.);

Investments in the capital of other companies ;

Transmission of securities and real estate assets within the framework of a succession.

In short, a patrimonial SC is differentiated by the fact that it offers partners the possibility of carrying out other activities in addition to the management of real estate. These activities must however remain in the civil domain . On the other hand, we can say that a SC Pat is similar to a civil holding company .

Procedures and formalities for the creation of a civil society

There are preconditions for the creation of a civil society, and which mainly concern the number of partners , the share capital , the nature of the activities ( corporate purpose ), but also the constitution of funds ( contributions ).

What are the conditions for creating a civil society?

Whatever its legal form (SCI, portfolio SC, property SC, SCCV or even professional SC…), creating a civil society requires a certain number of very specific steps and formalities . Before taking these steps and formalities, discover the various provisions relating to the creation of a civil society:

A civil society is made up of at least two partners ;

The number of partners is not limited , except in the case of a professional civil society whose partners are all physicians, and whose number cannot exceed 8 partners;

The partners can be of different nationalities , and be legal or natural persons ;

A share capital shall consist in the creation of a civil society, but without minimum required;

Each partner must make a contribution which can be either in cash (in money or cash), or in kind (material goods, assets, etc.), or even in industry (knowledge, etc.);

The share capital is divided between the partners in equal shares , and any transfer of shares can only be done with the approval of the majority;

The duration of existence of a civil society cannot exceed 99 years ;

The establishment must have one or more managers who can also be partners;

Each of the managers is representative of the company vis-à-vis third parties or establishments , and if the manager is a legal person, he must have a legal representative to replace him if necessary;

Each partner can decide to withdraw from the structure, partially or totally;

The partners adopt all measures and decisions concerning civil society during general meetings , or following a written vote;

What is Data Engineering?

Using data can help in many things, from personalized marketing campaigns to driving self-driving cars. Data processing specialists are responsible for analyzing the data and using it for various purposes.

However, they need good quality data to perform complex tasks such as predicting business trends. This is where data engineers come in.

Data engineering is the science of collecting and validating information (data) that data scientists can use what does an engineer do.

Role of Data Engineer: -

Data Engineers are the people who create the information infrastructure on which data science projects depend. These professionals are responsible for designing and managing data flows that combine information from various sources into a common pool (such as a data warehouse) from which it can be retrieved for analysis by data scientists and business intelligence analysts. Typically this involves implementing data pipelines based on some form of ETL model (extract, transform, and load) .

To create this information architecture, data engineers rely on a variety of programming and data management tools to implement ETL, manage relational and non-relational databases, and build data warehouses. Let's take a quick look at some of the most popular tools.

Data Engineering Tools: -

Pace Hadoop is the fundamental data engineering foundation for storing and analyzing large amounts of information in a distributed processing environment. Hadoop is not a single unit, but a set of open source tools such as HDFS (Hadoop Distributed File System) and MapReduce distributed processing engine.

Pace Spark is a Hadoop-compatible data processing platform that, unlike MapReduce, can be used for real-time stream processing as well as batch processing. He was almost in 100 times faster than the MapReduce, and seems to displace it in the Hadoop ecosystem. Spark offers APIs for Python, Java, Scala, and R, and can run as a stand-alone platform independent of Hadoop.

Pache Kafka is the most widely used data collection and food intake tool today. Kafka is an easy to configure and use high performance platform that can transfer large amounts of data very quickly to a target such as Hadoop.

Apache Cassandra is widely used to manage large amounts of data with lower latency for users and automatic replication to multiple sites for fault tolerance.

S QL and NoSQL (relational and non-relational databases) are fundamental tools for data engineering applications. Historically, relational databases like DB2 or Oracle have been the standard. But with today's applications increasingly processing huge amounts of unstructured, semi-structured, and even polymorphic data in real time, non-relational databases are now coming into their own.

What Are The Similarities Between Computer Science And Mechanical Engineering?

Computer Science and Mechanical science have very few similarities. However, one obvious subject area they possess accurate knowledge in is Mathematics.

Generally, computer scientists and mechanical engineers design, develop and test equipment that will be publicly used. They identify and solve problems using systems, modelling and mathematics.

What Are The Best Schools For Computer Science?

Most times, the length to which you can go in any career path is influenced by your choice of school. When choosing a school to go and study computer science, you can’t just make an abstract choice. You must be calm, do your complete research and then make a choice computer science average salary.

Do you need experience to find a job?

There's just one problem: Every position you come across for an "entry level" job requires two years of experience. How are we supposed to get the experience to step into the field of our dreams when we need prior experience, even for an entry level position? Welcome to the job seeker's dilemma.

Of course, you can still get an internship, but you have bills to pay. Paid internships are rare and those that exist do not usually pay well.

Whether you are entering the labor market for the first time or changing careers, contract work can help you overcome the barrier of two years of experience for entry-level jobs. Here's how : highest paying careers

1. Contract work enhances your CV

Applying for jobs that interest you can be exhausting and overwhelming. Instead of scrambling to fill out multiple job applications that may be outside of your level of experience, imagine landing a contract that will help you gain experience and skills.

Employers looking for contract help are more likely to recognize the value of your skills, training, and education. That's because hiring contract workers gives them the flexibility to try their luck with untested talent. And a good recruiter can also help them see what you have to offer beyond years of experience, like transferable skills, an eagerness and aptitude for learning, and a work ethic of being able to achieve.

Upon successful completion of contract tasks, you ':

Increase your skills and experience

Expand your CV

Network and meet people who do what you want to do

Obtain new professional references in the field of your choice that can demonstrate your abilities and past performance

Contract work can also lead to a permanent job offer depending on your (exceptional!) Performance, the employer's needs' or a contractual placement .

2. An experienced contract recruiter knows the market

Working with an experienced recruiter at a reputable staffing agency gives you access to something that you may not have with your own connections.

The best recruiters take the time to learn about your strengths and abilities and can promote you. They can get you through the door when your resume alone wouldn't do. And, if you land on a date, they can help you prepare for it.

Good recruiters also know employers. They understand that some employers are strict about the experience requirement, while others simply use it as a filter when they receive too many job applications.

3. You will get help to develop a career plan

Remember, recruiters are successful when you are successful. This means that they are committed to your short and long term success.

The best recruiters will work with you to develop a concrete career plan. They also have reliable information on available positions which do not require prior experience, but which will count towards that requested experience threshold of two years.

Have you ever thought that your perfect career might be the one you don't even know? Working in contract assignments allows you to discover a variety of jobs, industries and types of employers, giving you valuable insight into your strengths and what you love. You might stumble upon the career of your dreams as you develop the skills and experience that allow you to pursue it.

The WLAN indicator on the router is off. No wifi network

Today I decided to write an article on a very popular problem, when the WLAN light on the router is off and there is no Wi-Fi network. That is, when the router stopped broadcasting the Wi-Fi network. Owners of routers from different manufacturers face this problem: TP-Link, ASUS, D-Link, ZyXel, Tenda, Netis, etc. What kind of router you have is not important. If the Wi-Fi (WLAN) indicator on it has stopped lit and the Wi-Fi network has disappeared, now we will try to deal with this problem wlan.

Perhaps you have a slightly different problem when there is a Wi-Fi network, but the Internet does not work. In this case, see the article The router does not distribute the Internet via Wi-Fi. What to do?

And a separate article on Wi-Fi problems on TP-Link -  https://help-wifi.com/tp-link/tp-link-ne-rabotaet-wi-fi-router-ne-razdaet-wi-fi- set /

The WLAN indicator looks different on different routers (different manufacturers and models) . But almost every router has it. It usually blinks when wireless data is being transmitted. The bulb itself can be labeled "Wi-Fi", "2.4GHz", or "5GHz". Or maybe just an icon Wi-Fi indicator on the router

In any case, when the WLAN indicator on the router is off or flashing, this is no longer normal. As you already understood, WLAN is Wi-Fi. Wireless network.

The WLAN (Wi-Fi) lamp on the router is off

Most often, the problem is as follows:

Accidentally pressed a button to turn off Wi-Fi, which is found on many routers. After pressing it, the router stops distributing the Wi-Fi network, and of course the WLAN light does not light up. At the same time, the router continues to work, distributes the Internet via cable. But the device no longer sees the Wi-Fi network, since it does not exist.

Some kind of software glitch. In this case, rebooting, resetting, or flashing the router helps. Also, you need to check the Wi-Fi settings in the router control panel.

Broken router. I have already seen cases when the router stopped distributing the Wi-Fi network due to a technical breakdown. If all else fails, the Wi-Fi indicator is still off, then you need to carry the router for repair (possibly under warranty) , or buy a new one. If you have such a case, then see the article on choosing a router for your home .

Let's check this very button that turns off Wi-Fi on the router. We'll also check what's in the control panel. Since the problem is most often this.

The WLAN light is off, the router is not distributing Wi-Fi. What to do?

First of all, we take our router in hand and look for a button on it that is responsible for enabling / disabling the wireless Wi-Fi network. Usually, this button is labeled as "Wi-Fi", "Wireless On / Off", or simply with a wireless network iconWi-Fi indicator on the router

Button to turn off Wi-Fi on the router.  When the WLAN lamp is off

Some routers do not have this button.

If you find this button, then just click on it once. Wait a little and look at the WLAN indicator, it should light up. If this does not happen, then restart the router (turning off the power for a couple of minutes) , and try pressing the button again. You can press and hold for three seconds. It all depends on the router and settings. Anyway, this should help, and the router should be distributing Wi-Fi.

Checking the status of the Wi-Fi network in the settings

If you did not find the button, or after clicking on it the WLAN network did not appear, you can also check the status of the wireless network in the control panel of the router.

We connect to our router via cable, there are no options here, and go to the settings. If you do not know how to do this, then see the instructions for entering the settings of different routers . It may be that you will not be able to enter the control panel, in which case, look at this article. If you can't log in, and the recommendations do not help, then most likely the router just broke down.

If you are lucky and the control panel has opened, then look for the "Wireless network", "Wi-Fi", "Wireless" tab and open it. It all depends on the model of your router. Let's take a look at the most popular ones.

TOP-5 REASONS FOR REFUSAL TO DRAW UP TECHNICAL SPECIFICATIONS BY THE CUSTOMER

Are you still accustomed to working “verbally”: not to write down the technical assignment, but to decide everything in a 5-minute telephone conversation?

I bet that you associate the poor quality of the work with the unqualified performer, and not with the lack of technical specifications dark fiber.

This chapter is for you.

Despite the fact that we live in an era of simplification and rejection of bureaucratic procedures, we should not neglect the preparation of terms of reference for your contractors.

Let's take a look at the TOP-5 reasons for refusing to draw up a technical specification by a customer:

“I don’t even know what it is and how to draw up your TK”

This article has been written especially for you. Also, for beginners in the preparation of technical specifications, there is an alternative option.

Almost every freelancer has a brief - a questionnaire that gives an idea of ​​the job and requirements.

By filling out the brief in detail, you can kill two birds with one stone: and give the performer an exact understanding of what they want from him, and write the first terms of reference in life, the main thing is as detailed as possible.

“Why complicate your life? We will quickly discuss everything on the phone and continue to work "

This is the road to nowhere. Firstly, you will not have a file with all the requirements that you set for the performer.

Secondly, memory is a very tricky thing. You (or even worse, the performer) can simply forget everything that you asked for during the conversation.

Plus, you have no guarantee that the employee you are hiring for the project work will be close to you and will be able to come to the organizational meeting.

The world is gradually moving to remote work.

Your performer may be on the other side of the ocean, and correspondence with a discussion of all the working moments sometimes lasts months.

Unlike the TK, which is drawn up in half an hour and does not require clarification.

"I don't have time for all this bureaucracy."

In fact, only you need the terms of reference. After all, the performer does not care whether the work will sell him, whether it will increase the recognition of YOUR brand.

This is your project, your responsibility and your face, so it is worth finding a little time to get the result you want, and in the long run achieve the goals that you have set for yourself.

“We worked before without any technical specifications and everything was fine”

There are only 2 options here: either you are incredibly lucky, or your views coincide 100% with the vision of the artist.

In both the first and second cases, I recommend not to lose the contractor, because this happens very rarely.

"First you need to know the price of work, and not throw off the TK for everyone."

Not a single contractor will be able to tell you the exact price if he does not know the details of the work.

For example, you are looking for a person who will write the text and ask for a price.

The topic, volume, requirements for uniqueness, semantic load - all this affects the cost of the text.

Therefore, I recommend throwing off the TK to all candidates for the role of the executor. So you will receive prices, and the performers, in turn, will know whether the task is within their power or not.

How to avoid mistakes in the preparation of technical specifications

How to find a sample site

Before filling out the technical assignment for the development of a site, the customer is recommended to analyze the sites of competitors in order to get a more accurate and broad understanding of the tasks to be solved. You can also familiarize yourself with ready-made website templates for the desired topic. They can be taken as a basis for developing algorithms for your own site.

In addition to online stores, there are other types of sites: business cards, blogs, portals, etc. It is on the basis of the type that the design should be chosen.

If you need a business card site, pay attention to the sites of private specialists in different areas. For example, to this website of an accounting services company: sow meaning

Sample Accounting Company Website

The site is made in a minimalistic design. Light colors and shades are used, key elements are blue. All together looks harmonious and does not interfere with acquaintance with information. The page contains important menu items: "Services", "Cases", "About us". You can also find answers to frequently asked questions and get advice by ordering a call or by calling yourself.

In addition to competitors' sites, look for interesting examples of layout and design on thematic resources.

So, the TemplateMonster website contains a large number of templates. Among them, you can find a suitable one and indicate it in the TK as an example:

Website templates at TemplateMonster

The Timeweb site also contains many examples of blogs, business cards, online stores, and other types of sites. To get acquainted with the demo version, just click on the corresponding icons from the list:

How to describe site design

First of all, the customer needs to decide what type of site is needed. The scope of the designer's work and the style of the site depend on this. For example, if you are planning to create a corporate website, then the design will be simple, in the corporate style of your company. For blogs and business cards, it is important to attract the attention of the audience, therefore, the design of these sites has a place for interesting animation and interactive elements.

It is important to convey to the designer your vision of the future site and all its elements as accurately as possible. To do this, you need to describe in the TK your preferences regarding the appearance of the site, namely the following information:

main palette (light or dark),

background color (or example image),

the need to follow the corporate identity of the company,

fonts.

The designer will do his job much faster and more accurately if the appearance of each element of the site is disassembled in the TK:

navigation tools,

hats,

menu,

text blocks, etc.

So, for example, you can specify the preferred shape, color and how to expand the navigation bar

Navigation elements are usually located in the header of the page. It is here that the individuality of the site is formed in the eyes of the user. According to the design canons, the header should occupy a space in the range from 200 to 300 pixels.

In the corresponding column of the technical assignment, you also need to place samples of the company logo and indicate corporate fonts.

Light colors are often chosen for the background of the site. The reason for this decision, as a rule, is that it is more convenient for the user to read text, view images and study other content on a light background.

Text blocks should be designed in accordance with the overall design of the site. At the same time, it is important that the visitor does not have any difficulties in reading the text. In terms of fonts, if the customer doesn't have specific preferences or corporate fonts, Tahoma, Verdana and Arial are the most commonly used ones. The optimal size is from 12 to 16 px. In the TK, you can also indicate how the customer sees the headings. They should be in harmony with the main text, attract the user's attention, but at the same time not interfere with reading.

If the site contains large articles, we recommend that you consider the design of the content block. It is needed for more convenient familiarization with the information and easy transition to certain blocks of the article. To do this, the content points must be made anchors to certain subheadings of the text. Their design may differ from the rest of the links in the text or on the page as a whole.

At the last stage of approval, the developer usually offers the client samples of website designs of the same or related topics, as well as sketches of page elements. The customer can make his own adjustments. After agreeing on all the nuances, stages of work, the method of payment and the timing of the project, the customer approves the TOR, and the developer accepts the order.

How to avoid mistakes in the preparation of technical specifications

When compiling and checking the terms of reference for the development of a site, it is important to take into account even the smallest nuances. Otherwise, you can make such mistakes:

contradictions in requirements,

unclear wording,

principle "2 in 1",

lack of a clear deadline,

responsible persons are not indicated,

too high level of detail,

too many terms

lack of information.

The terms of reference should not contain contradictory statements. For example, if it is assumed that the site will be modernized or modified, then it is not worth prescribing in the technical specification the preparation of those elements that cannot be changed. Make sure that the specified items are not mutually exclusive.

Requirements for the site being developed and the process of its creation should be described in detail, but concisely. Remove vague and incorrect wording from the text.

It is important to prescribe not only the main deadline, but also the deadline for each stage. This will make it easier for both parties to regulate processes.

Indicate in the TOR the employees responsible for each stage of development. For example, the programmer Ivan Petrov is responsible for the technical implementation, and the designer Elena Kuznetsova is responsible for the appearance. Each specialist, according to the document, is responsible for the quality performance of his work on time.

An overly detailed description can be confusing for both the developer and the customer. There is a possibility that the extra information will raise a number of additional questions from the contractor. As a result, everyone runs the risk of wasting time and effort figuring out unnecessary details.

The TK should be clear to both the customer and the contractor. Therefore, the document should be drawn up in a language understandable to both parties. We recommend avoiding professional terms or using them only when absolutely necessary.

Although some columns in the TK are optional, we advise customers, if possible, to fill in everything and indicate comprehensive information for each requested item. This approach helps both parties: the customer - to more clearly imagine the desired result, the performer - to perform his work as efficiently as possible.

The Creative Problem Solver’s Guide to the IT Help Desk

IT is a profession that’s built around the hard science of computing, so for those casual users who haven’t spent much time investigating the ins and outs of computers, it might sound a little dry. Or intimidating. But while there’s plenty to learn about the way computers and networks function in order to manage the technology in a professional environment, hard facts are hardly the half of it. A help desk technician or technical support specialist who’s been in the game for even just a little while can tell you that there’s an art to IT: the better part of providing high-quality service is bringing knowledge to life with creative thinking comptia jobs.

Every help desk ticket poses its own unique challenges, so being able to think on your feet and use creative problem-solving skills is a key to success in IT at every step of the game. This is why the latest update of CompTIA A+, the foundational entry-level IT certification, tests as heavily on the ability to think through problems as it does on the knowledge it takes to recognize them.

If you’re considering IT as a career path, don’t fear that you might be setting yourself up for something boring. Help desk-level IT work is anything but that. To understand how, take a look at the following ways creative problem-solving skills come into play, every day, at the help desk.  

Figuring Out What an End User Means Versus What They Say  

For the tier 1 help desk technician, simply figuring out what the problem is can take a lot of creative horsepower. That’s because, depending on the end user’s technical abilities, what they ask is not always what they mean.

One of the most common things a help desk pro hears is, “My computer doesn’t work.” This could mean a lot of things – and drilling down to figure out the simplest problem can be a complicated process.

For instance, if an end user complains about a cursor that won’t move around on the screen, that could indicate a computer that has momentarily locked up, a USB mouse that’s not plugged in or even the presence of malware.  Help desk pros even run into people who confuse an internet browser window with network connectivity.

It’s all part of the gig, and managing it requires IT pros to be able to put themselves in the shoes of the less tech-savvy – to think broadly about what’s happening on the other end of the call or chat, reverse-engineer the thought process and figure out what’s actually going on, and then communicate a solution in the way that makes the most sense.
