Q: A friend I know moderately but not terribly well sends me messages via every available medium – text message, messaging app, email and Facebook – far more often than I want to respond. How do I get her to back off without being rude? A: I think what you’re asking is how to de-escalate the friendship without losing the friend, and the answer is it may not be possible. It’s a problem I think about relatively frequently, because it’s tricky, and it feels disloyal, and love and friendship are two of the most important things in life and we reject them at our peril. On the other hand: what you’re talking about – shy of stalking, but a bombardment that suggests a disparity in you and your friend’s relative needs – is difficult and something that the internet has only made worse. Where and when it’s OK to ignore someone and when it isn’t has always been hard to work out, but trying to parse which messaging service is optional and which entails an obligation to reply isn’t straightforward. I think a lot of it depends on how sensitive this person is to your nonverbal cues. (And, I would add, it might depend also on where you are coming from. I am an English person who is very much in favour of passive aggression and will take almost any steps to avoid confrontation. You, on the other hand, may be American and regard this as a form of time-wasting cowardice. Let’s address both.) The passive-aggressive response is, as with Pavlov’s dog, to try to mould this person’s expectations to suit your desired response. So you wait a couple of days before replying to a message and, if it has been sent across multiple mediums, you pick the one that is least likely to generate an automatic reply (avoid IM and text messages at all costs unless you are ready to have a conversation). That leaves email, now the lumbering old lady of digital communication, and thank God we still have it. Ignore chasers of the “Are you there?” / “Everything all right?” kind. After a couple of days, send a cheerful, short response, either giving a reason why you’ve been out of touch, or not – there’s an argument that you shouldn’t have to explain yourself, but this always feels too harsh to me – and promising to catch up soon. I’m trusting that this person is neither having a nervous breakdown nor is in need of genuine help. We’re talking about the kinds of people – and there is one in every social group – who send out 25 phishing texts declaring themselves to be in need of a chat and are happy with whatever comes in. They don’t need you, they need a warm body who will listen and be vaguely sympathetic. I’m not talking about narcissists either, who do all of this but with an added layer of malevolence. There’s no manipulation here other than to get you to respond. And it is probably the case, since you don’t want to lose the friendship, that once you have them on the line, you have a lovely chat. You just don’t want to speak to them every night. What we’re talking about here is over-communicators who have been unleashed and emboldened by the vast number of new channels of communication available to them. Now, you, the person who doesn’t want to be in touch every two days, looks like the freak. This brings me to another point. You can decide that the aggravation isn’t worth it. It’s a strange thing that people whom you rarely see have the power to invade your consciousness more frequently than the people you love. I came late to this realization a couple of years ago when I realized I was spending minutes of every day scorning the line drawings of unicorns and mad screeds put by a second cousin on Facebook. I was giving her more thought than my nearest and dearest and promptly unfollowed her. There is often a performance aspect to over-communicators who, in my experience, operate under a well developed persona, one that requires a lot of feeding. That’s passive aggression. Sometimes people can be trained, and sometimes they can’t, in which case, you may have to graduate to the more grown up and very un-English way to proceed, which is to send one of those emails I instinctively dislike but that I can see are more evolved in their way. These are the ones that start, “Don’t take this the wrong way” or “I’m having trouble bearing up under my weight of correspondence” (although perhaps not phrased as if you have a stick up your bum) or “I’m just giving you a heads up so you’re not offended if I don’t immediately respond.” Maybe it’ll work. Maybe it’ll just prolong the agony. Maybe the friend will think, wow, why am I friends with this person in the first place? I think my main point is that you don’t have to sign up to a schedule of frequency set down by somebody else. (Unless it’s your mum). And while this problem has given rise to a language I hate, there is just no other way to say it. Be polite, be firm and – deep breath – assert your boundaries!

Effective 100Gb/s single-mode optical transmission can be achieved over 100m of multimode fiber by using advanced modulation schemes and digital-signal processing. Global data traffic is increasing at an unprecedented rate. This increase is due in large part to the rise of cloud computing services, multimedia web applications, and Internet-of-Things technologies. Indeed, the bandwidth requirements imposed by these applications are expected to double network traffic in data centers within five years.1 To cope with these demands, the viability of using new photonics technologies and approaches to improve the performance (i.e., to increase the capacity and reduce the latency) of data-center interconnects must be explored. Furthermore, these new approaches must ensure a reduced carbon footprint and lower operating costs.2 A large amount of research has recently been carried out on vertical-cavity surface-emitting lasers (VCSELs) with the aim of meeting these requirements. VCSELs represent one of the most appealing technologies for application to optical interconnects because of the advantages that they provide (e.g., low power consumption, reduced fabrication cost, the feasibility of on-wafer testing, and high coupling efficiencies).3 Additionally, the rapid development of electronics has led to the increased efficacy of advanced modulation techniques over larger bandwidths, thereby significantly increasing the spectral efficiency of communications systems. Combining these new photonics technologies with advanced modulation formats has enabled the development of single-polarization and single-wavelength intensity modulation/direct detection (IM/DD) high-speed links. A number of recent research efforts have achieved effective bitrates of close to 100Gb/s using VCSELs. Specifically, effective bitrates of 94Gb/s over 2m of OM4 multimode fiber (MMF) with an 850nm VCSEL, 95.8Gb/s with a 1550nm VCSEL, and 71Gb/s over 7m of OM3 MMF with an 850nm VCSEL were achieved by means of, respectively, four-level pulse amplitude modulation,4 discrete multitone (DMT) modulation,5 and non-return-to-zero direct modulation.6 By exploiting the versatility of a multiband approach (i.e., carrierless amplitude phase modulation, CAP),7 we have successfully transmitted an effective bitrate of over 100Gb/s through 100m of OM4 MMF.8Multiband CAP modulation provides the same advantages that are characteristic of DMT modulation (i.e., bit and power loading), but with a lower peak-to-average power ratio. These features allow the non-flat frequency response of the transmission channel to be mitigated and the spectral efficiency to be maximized. Additionally, as a result of recent developments, single-mode-operation VCSELs are now available (see Figure 1).9 These enhanced laser sources reduce the transmission impairments that typically arise as a result of intermodal dispersion. As a result of this, their bit-error-rate (BER) performance is below forward-error-correction (FEC) thresholds, and longer links are achieved. In our experimental study, we generated a multiband CAP signal consisting of 10 bands—each with a baud rate of 2.5Gbaud—to modulate the 850nm single-mode VCSEL. By employing bit- and power-loading techniques, we assigned modulation schemes to the bands, ranging from a 64-symbol constellation (64-CAP) to a 4-symbol constellation (4-CAP). We carried this assignment out according to the signal-to-noise ratio of each frequency band to ensure a BER below the 7% overhead FEC threshold (i.e., 3.8×10−3) for all bands. Figure 2 shows the received electrical spectrum—and the corresponding symbol constellation and error vector magnitude—of each band after transmission over 100m of OM4 MMF. By adding the bitrate of each band, we calculated that information was transmitted at a total bitrate of 107.5Gb/s. Furthermore, after removing FEC redundancy, we achieved an effective bitrate of 100.47Gb/s. The central frequencies of each band were separated from their neighbors by 2.55GHz, and the first band had a central frequency of 1.3125GHz. The total bandwidth occupied by all bands was 25.5GHz, resulting in a spectral efficiency of 4.21bit/s/Hz. We were also able to increase the resilience of the transmission to optical-link impairments by reducing the modulation order of the bands and, consequently, decreasing the total bitrate. Such a reduction enables longer links to be reached. Using this scheme, we achieved a maximum total bitrate of 112.5Gb/s in back-to-back tests. Furthermore, by decreasing the total bitrate to 85Gb/s, we achieved transmission over 1km of OM4 MMF with a BER below the 7% FEC threshold (see Figure 3). The bitrates that we achieved over different MMF lengths, and the corresponding modulation schemes of all bands, are shown in Table 1. Table 1. Set of modulation schemes for each multimode fiber (MMF) length tested (i.e., 0, 100, 200, 600, and 1000m) using 2-, 4-, 16-, 32-, and 64-CAP modulation.7 Data transfer carried out using a VCSEL. (Click on table to enlarge.) In summary, we have experimentally validated the feasibility of achieving 100Gb/s short-range links with cost-effective MMF and 850nm VCSELs. The flexibility provided by our multiband CAP-modulation approach enables transmission rates to be maximized with limited power and bandwidth resources. The advanced digital-signal processing techniques and high-order modulation schemes (i.e., that give rise to rates of over 100Gb/s) are enabled as a result of the increased processing capabilities of today's electronics. In our future work, we will focus on assessing and implementing the necessary analog and digital technologies to enable these high-speed optical links in real time.

According to several independent reports from insiders in South Korea, Samsung expects the Galaxy S8 and Galaxy S8+ to be its best-selling smartphones of all time. Sales of last year’s Galaxy S7 and S7 edge have reportedly topped 52 million units so far, which makes that quite a tall order. Considering how much buzz Samsung managed to stir up despite its Note 7 debacle, and considering how incredibly impressive the new Galaxy S8 and S8+ are, the company’s supposed 60 million unit target could be well within reach. And needless to say, these high-priced, high-margin phones will do wonders for Samsung’s bottom line. But Samsung is much more than just a smartphone maker, and the company has one of its other key divisions to thank for the remarkable Q1 earnings it just reported. Don't Miss: After two weeks with the Galaxy S8, I still think the iPhone 7 Plus is the world’s best phone Samsung on Thursday announced its audited first-quarter earnings, and they were nothing short of explosive. On the back of a huge performance boost in the company’s massive components division, Samsung posted a net profit of 7.68 trillion South Korean won (US$6.8 billion), a 46% increase from the year-ago quarter. In fact, Q1 2017 marked Samsung’s most profitable quarter in three years. Revenue was up slightly to 50.55 trillion won in the March quarter, while operating profit ballooned to 9.90 trillion won, a 48% increase over the same quarter last year. The company’s semiconductor division found the most success in Q1, raking in an operating profit of 6.31 trillion won on consolidated revenue totaling 15.66 trillion won. Samsung said improved sales of its NAND flash storage modules and DRAM memory chips had a big impact on Q1 performance, and it expects its semi business to continue to grow in the second quarter. Strong demand for Samsung’s display panels also contributed 1.30 trillion won in Q1 operating profit on 7.29 trillion in sales. Samsung’s Mobile Communications and Networks Businesses, which now comprise its IM Division, pulled in 2.07 trillion won in operating profit on the back of revenue totaling 23.50 trillion won. Considering the April launch of its new Galaxy S8 and S8+ flagships in addition to continued strength in the company’s semi business, things may be looking even brighter for Samsung in Q2 2017.
